Even the worst mass extinction had its oases

Some earlier plants might not have made it through the extinction since rock layers from the onset of the End-Permian Mass Extinction showed a decrease in pollen and spores, as well as fewer plant species. Other species were scarce because they had not been as well-preserved as others; the team did not automatically assume the scarcity of a plant that did not fossilize meant it had gone extinct.

While there were plant species that ended up being victims of the Great Dying, analysis of species through spore and pollen told the team that only about 21 percent of them succumbed to extinction.

Life will not be contained

The fossils also revealed the presence of plant species known to grow near lakes, which meant an environment that most likely provided drinking water for land-dwelling animals. Fossilized spores farther from what were once the banks of an ancient lake or the edge of a lakeplain suggest it was surrounded by a forest of gymnospermous trees, such as conifers or ginkgo, and ferns.

Because the researchers found so many spores from plant species known to grow in humid climates, they think the regional climate before the extinction was either humid or sub-humid, with plenty of rain. It was a lush environment that would see dry periods during the mass extinction event, but not be completely devastated.

Despite some species of plants vanishing, those that were found to have survived during and after the extinction mostly belonged to conifers and pteridosperms (now-extinct plants similar to ferns), which showed “a remarkable ability to adapt to drought,” as Liu and his team said in the same study.

The drought turned out to be only temporary. Younger rock layers were found to contain a greater abundance of pollen and spores from species that grew during the extinction event. The types of plants represented suggest a climate that had returned to subhumid and was more habitable.

Fossils of animals found at the site support its role as a haven for life. From the herbivorous Lystrosaurus (not a dinosaur), which looked something like a walrus with legs and a shovel face, to the carnivorous chroniosuchians that resembled giant lizards and fed on insects and small amphibians, the refugium in what is now Xinjiang kept life going.

Both flora and fauna would soon spread across terrestrial environments once again. Life on land flourished only 75,000 years after the End-Permian Mass Extinction, so life really does find a way.

People in this career are better at seeing through optical illusions

A hint came from our previous work comparing mathematical and social scientists’ judgements of illusions (we work in universities, so we sometimes study our colleagues). Social scientists, such as psychologists, see illusions more strongly.

Researchers like us have to take many factors into account. Perhaps this makes us more sensitive to context even in the way we see things. But also, it could be that your visual style affects what you choose to study. One of us (Martin) went to university to study physics, but left with a psychology degree. As it happens, his illusion perception is much stronger than normal.

Training your illusion skills

Despite all these individual differences, researchers have always thought that you have no choice over whether you see the illusion. Our recent research challenges this idea.

Radiologists need to be able to rapidly spot important information in medical scans. Doing this often means they have to ignore surrounding detail.

Radiologists train extensively, so does this make them better at seeing through illusions? We found it does. We studied 44 radiologists, compared to over 100 psychology and medical students.

Below is one of our images. The orange circle on the left is 6% smaller than the one on the right. Most people in the study saw it as larger.

Here is another image. Most non-radiologists still saw the left one as bigger. Yet, it is 10% smaller. Most radiologists got this one right.

It was not until the difference was nearly 18%, as shown in the image below, that most non-radiologists saw through the illusion.

Most people get this one right. Credit: Radoslaw Wincza, The Conversation

Radiologists are not entirely immune to the illusion, but are much less susceptible. We also looked at radiologists just beginning training. Their illusion perception was no better than normal. It seems radiologists’ superior perception is a result of their extensive training.

According to current theories of expertise, this shouldn’t happen. Becoming an expert in chess, for example, makes you better at chess but not anything else. But our findings suggest that becoming an expert in medical image analysis also makes you better at seeing through some optical illusions.

There is plenty left to find out. Perhaps the most intriguing possibility is that training on optical illusions can improve radiologists’ skills at their own work.

So, how can you learn to see through illusions? Simple. Just five years of medical school, then seven more of radiology training and this skill can be yours too.The Conversation

Old Bolt, new tricks: Making an EV into a backup power station with an inverter


Putting big batteries to use

Using a custom kit to make a budget EV offer some emergency power.

Back when EV enthusiasm was higher, there were fits and starts of vehicle-to-home concepts and products. If EVs and their ginormous batteries are expensive, resource-intensive purchases, the thinking went, maybe we should get something more out of them than just groceries and school pick-ups. Maybe we could find other things for that huge battery to do during the 95 percent of time it spends parked in or near our homes.

An EV powering your whole home, or even pushing power back to the grid, is something higher-end EVs might do at some point with some utilities. I have a Chevy Bolt, an EV that does not have even a three-prong 110 V plug on it, let alone power-your-home potential. If I wanted to keep the essentials running during an outage, it seemed like I needed to buy a fuel-based generator—or one of those big portable power stations.

Or so I thought, until I came across inverter kits. Inverters take the direct current available from your vehicle’s 12V battery—the lead-acid brick inside almost every car—and turns it into alternating current suitable for standard plugs. Inverters designed for car batteries have been around a long time (technically, the “cigarette lighter” port on a car is an inverter), opening up both novel and emergency uses. The catch is that you have to start the car’s gas engine often enough to keep the battery charged.

What’s different about this Bolt-specific kit is that, as the inverter pulls power from the 12 V battery, the car’s larger battery, the high-voltage one that makes it actually drive, steadily refills it. And given that it’s an EV without emissions, it’s OK to keep it running in the garage. It’s by no means a whole-home solution—my kit maker, EV Extend, recommends drawing just 1,000 watts of continuous power so as not to drain the battery too far or damage the electronics. But it’s certainly better than having only flashlights, USB battery packs, and the power utility’s website open on your phone.

What can you do with 1,000 W, plus a bit of “surge” overhead for devices that kick on strong, like a refrigerator? I can’t run my home’s central HVAC system, so an outage in the depths of a DC summer, or the occasionally painful winter, would still be unpleasant. There are only three plugs, and they’re inside the car hood, so everything that needs power has to be reached by extension cord (and you don’t want to go too far with those). The car is also unlocked and running, with its key fob nearby, so it can’t be left alone.

But for backup power I never planned to have, in an area where outages are less frequent, I have something like minimum viable backup power. With properly rated extension cords, I could run fans, a small space heater, or a single-room-sized window A/C unit for a day or two on conservative settings. I could, if my fiber provider is still up, keep the Internet and router running. At a minimum, I could keep a lot of distraction devices running with the Bolt’s 64–66 kW battery (assuming I fully charged it before an outage).

I have not had a chance to really test this inverter, as the residential power in Washington, DC has been stubbornly reliable since I bought it. But I did run it for about an hour mid-day to try out some of my assumptions.

What’s in the kit

I bought a $444 kit from EV Extend, which specializes in inverter packages for the non-flashy and early adopter EVs: Chevy Bolts and Volts and Nissan Leafs. I opted for a 1,500 W pure sinewave inverter, capable of briefly handling surges of up to 3,000 W. The inverter itself is a commodity, and you can find it lots of places. The things I was really buying with this kit were:

  • Quick connect/disconnect couplings for attaching to the 12V battery
  • A safety fuse between the 12 V battery and inverter
  • Cables and connectors, cut and crimped and soldered specifically for the angles and spaces of the Bolt’s front compartment
  • Detailed instructions on how to attach, run, fit, and use everything

The owner of EV Extend makes a point of not offering his instruction manuals publicly. This is in part for “low-volume niche market” reasons. But it’s also because of a real concern that folks will see EV Extend setups, do some “I could rig that together” thinking, and expose themselves to a whole bunch of electrical, mechanical, or safety problems. He’s not opposed to DIY-ers, he writes, so much as he’s concerned about wiring quality and bad assumptions.

From the images on EV Extend’s site and various Reddit installs, you can get the gist. A big brick of an inverter, with two thick cables running to a gray plug, and another gray plug running out from the 12 V battery area, easily tucked away (with velcro) when not in use. You can buy more or less surge protection, opt to skip pure sinewave inversion (not a great idea if you’re powering electronics), or upgrade and get a remote switch. But they are all largely the same.

Among the frequently asked questions on the product page is “will this void my warranty?”

The answer: No, it should not, because the Magnuson-Moss Warranty Act still exists, so there needs to be proof that this damaged your 12 V system. But there is also the unwritten caveat that it can still be very painful if your car maker or dealer is not up on their consumer rights laws.

Just a little 12-hour vehicle panic attack

My installation took about 20 minutes. It involved some socket-wrenching, and I had to saw off an inconvenient but inessential plastic bit. The toughest part involved fishing some stiff, thick wire through a space between the coolant tank and a metal bracket (which the manual warned about).

That night, I plugged in the inverter, turned on the Bolt, flipped on the inverter, and plugged in a USB-C wall plug. I connected an iPad, it started charging, and I felt a weird sense of accomplishment at having found one of the most expensive and inefficient ways to watch YouTube. For a few hours, I held some project-completing pride.

Later that night, the myChevrolet app flung about a dozen notifications at me. The gist: Every single system on the Bolt was failing, I needed to have it towed to a dealer, and I was wrong to try and redistribute its precious electrons. These were bad messages to receive in the middle of brushing my teeth, and sleep did not come easy.

Why the panic? The majority of EVs, however sophisticated, are heavily dependent on their old-fashioned 12 V batteries. This is due in part to how many of an EV’s ancilliaries—locks, lights, infotainment, power steering, and more—are designed to run at 12 V, in common with the rest of the auto industry. But it’s also because when an EV’s higher-voltage traction battery is off, it needs to be fully off and de-energized, and the 12 V helps switch it off and keep residual systems running (Inside EVs has a good explainer on this). Disconnecting my 12 V battery, even for just a minute to attach a connector, gave the car fits about lacking this crucial reserve of juice.

It’s weird, and it can be quite frustrating in the wrong circumstances. But the next morning, I started the Bolt, let it idle for a few minutes, and all the divinations of doom disappeared from the Chevy app. Six months later, I have yet to see any others. I’ve taken my car in for a general check-up since, and the mechanic made no note of my velcro-anchored connector.

A deeper test: Pretend office outage

The inverter hook-ups were set, but household power remained stubbornly stable for months, so I decided to stage a pretend outage. Could the Bolt keep me and my wife reasonably comfortable in my office, the next room over from the garage? Could I keep a space heater or window air conditioning unit running, with occasional kick-on surges? What about the fridge? And how annoying would it be to have the car running in neutral in my garage the whole time?

Here’s what I figured could fit into 1,000 W from the inverter and its three plugs, using appropriately sized and rated extension cords:

  • At their lowest settings, either a bigger space heater (750 W), or a 15,000 BTU window unit (350–450 W, running roughly 50 percent of the time)
  • The fiber optic network terminal (ONT) and my Ubiquity network gear (Dream Machine Pro and two power-over-Ethernet access points)
  • My whole working desk setup: monitor, M2 MacBook Air, Sonos speakers, too many peripherals
  • If possible, the refrigerator (typically 60 W, with surges up to 1,200 W and defrost cycles at 240 W)
  • A bit of overhead, should I need to run anything else, like lamps, off my desk’s power strip

I unplugged the Bolt, opened the hood, placed the inverter on a reasonably flat part of the compartment (next time, I will have a flat piece of wood to place there), turned on the car, and flipped on the inverter. So far, so good!

Because the car was in park, it would automatically shut itself off after two hours. A number of committed campers and preppers on Reddit have suggested putting the car in neutral, engaging the parking brake (or putting chocks behind the rear wheels), and exiting the car from the passenger side (as opening the driver side door can make the car auto-shift for safety). Because it’s not in park at a low speed, the Bolt will make a whirring noise for pedestrian safety. I could temporarily cancel it by pulling the right fuse from the engine compartment box, so long as I left a note for myself with big letters to put it back in.

I first plugged in my desk and all its accompaniments, then nudged and woke up my laptop and monitor: 14.7 watts. That seemed a bit low, given that monitors are typically more than 20 watts, but the inverter is perhaps slow to report the full draw. Still, there was lots of headroom remaining.

Adding in the fiber optic modem, the Dream Machine Pro router (specified at a 50 W maximum power draw), and its PoE-based devices boosted the number to 90 watts. That left 910 watts, which felt like a lot until I plugged in the big space heater and set it to its lowest setting. Once the heater had been on for a bit, I was at 850–860 watts, combined with the other gear. I knew space heaters were inefficient in a broad sense, but now that fact is burned into my brain in little red digits.

All three plugs in—desk, networking gear, space heater—and the 850 watts the inverter eventually settled at once the heater ran a while.

All these things ran off the inverter for about 30 minutes (I wrote the previous two paragraphs with mostly inverter power), floating between 810 and 920 watts, and I saw the car’s projected mileage dip one mile when I checked on it. If I had the Bolt fully charged, I might get a maximum of 60 hours of this, or 48 hours at my typical 80 percent charge, give or take some resistance and use variables. Given what I learned, I would need to use a smaller space heater or very light air conditioning if I also wanted to keep the fridge running without nervous monitoring (and make up for some loss to an extension cord). That, or hope the power only goes out during comfortable temperatures.

But I’m using the Bolt and inverter as a just-in-case option, not something I would lean on if regular multi-day outages were occurring. It would also be quite useful for car camping, though I can’t speak to that personally. The process has, like most DIY projects, taught me some things: about power draw, EVs, and my priorities. If you have a similarly nifty but not exactly new EV, consider checking out your inversion options for it—after you fully understand the limits and know-how required.

Behind the scenes of The Electric State

The directors adopted more of a colorful 1990s aesthetic than the haunting art that originally inspired their film. While some fans of Stålenhag’s work expressed disappointment at this artistic choice, the artist himself had nothing but praise. “When you paint or draw something, you can do anything,” Stålenhag has said. ‘There are no constraints other than the time you spend painting. To see a live action movie make something I painted and to see it so truthfully translated impressed me on all levels.”

Bringing a vision to life

The task of bringing that aesthetic to the screen fell to people like Oscar-winning production designer Dennis Gassner, whose many credits include Barton Fink, Bugsy, The Hudsucker Proxy, The Truman Show, Blade Runner 2049, Skyfall, Quantum of Solace, Spectre, Into the Woods, and Big Fish. (In fact, there’s a carousel featured in the design of the Happyland amusement park that Gassner first used in Big Fish.) He and Richard L. Johnson (Pacific Rim, The Avengers) led a team that not only designed and constructed more than 100 sets for the film, but also created a host of original robot characters to augment the ones featured in Stålenhag’s book.

On set during filming of The Electric State Netflix

All the robots featured in the film have their own stories, “distinct personalities and emotional arcs,” per Anthony Russo. The directors wanted the robots to “feel authentic to the alternate 1990s but still had roots in recognizable designs,” according to Joe Russo—the kinds of things one would see in vintage commercials, shopping malls, corporate branding, and so forth. “Everything is story,” Gassner told Ars. “Story is paramount. What story are you telling? Who are the characters in this story? What are their environments? How do they feel within the environments?”

Gassner’s team designed about 175 robots all told, selecting their favorites to be featured in the final film. “It’s like a great casting call,” Gassner said. “So we played a lot, there was a long time of development in the art department between myself and a vast team of artists. We worked very closely with the visual effects department, but what the characters look like are part of the art department, and our collaboration with Joe and Anthony Russo on the study of characters. That was the fun part, getting the shape right, the character right, the color right, the clothing right.”

i-threw-away-audible’s-app,-and-now-i-self-host-my-audiobooks

I threw away Audible’s app, and now I self-host my audiobooks


Stream your DRM-free audiobooks to devices yourselves, without the cloud’s chains.

We’re an audiobook family at House Hutchinson, and at any given moment my wife or I are probably listening to one while puttering around. We’ve collected a bit over 300 of the things—mostly titles from web sources (including Amazon’s Audible) and from older physical “books on tape” (most of which are actually on CDs). I don’t mind doing the extra legwork of getting everything into files and then dragging-n-dropping those files into the Books app on my Mac, but my wife prefers to simply use Audible’s app to play things directly—it’s (sometimes) quick, it’s (generally) easy, and it (occasionally) works.

But a while back, the Audible app stopped working for her. Tapping the app’s “Library” button would just show a spinning loading icon, forever. All the usual troubleshooting (logging in and out in various ways, removing and reinstalling the app, other familiar rituals) yielded no results; some searching around on Google and DuckDuckGo led me to nothing except a lot of other people having the same problem and a whole lot of silence from Audible and Amazon.

So, having put in the effort to do things the “right” way and having that way fail, I changed tacks and fixed the problem, permanently, with Audiobookshelf.

Audiobookshelf

Audiobookshelf is a self-hosted audiobook and podcast server, and after two weeks of use, so far it works vastly better than trying to stream within Audible’s app. My wife can now actually listen to audiobooks instead of staring at a spinning loading icon forever.

To get Audiobookshelf running, you need something to run it on—a spare desktop or other computer you’re not using should fit the bill, as Audiobookshelf’s requirements are relatively meager. You can either install it via a Docker image, or on bare metal on Windows or several different Linux distros. (The Linux distro installations include a repository for handling updates via your system’s update method, so you won’t have to be manually installing releases willy-nilly.)

Since I already have a Proxmox instance up and running on my LAN, I chose to install Audiobookshelf inside an Ubuntu 24.04 LXC container using the “bare metal” method. It’s not particularly resource-intensive, using about 150MB of RAM at idle; as noted above, if you don’t have a server handy, running Audiobookshelf via Docker on your desktop or laptop shouldn’t be much of a burden on your memory or CPU. (It does suck up a fair amount of processing power when it’s bulk-importing or matching books in your library, but these aren’t things you’ll be doing terribly often.)

Getting it going

Once you’ve got Audiobookshelf installed via your preferred method, your next stop is creating and then populating your library. You can do this directly in the application’s web interface, if desired:

Screenshot of Audiobookshelf upload page

I chose to do it the old-fashioned way and copy files into the library location myself, which also works.

There are a number of ways to make sure Audiobookshelf properly ingests and categorizes your books; first, it is aware of and respects metadata tags if your books have them. If your files lack tags, the Audiobookshelf docs provide several other methods of organization using file and directory structure. Between tags and being able to just name things per the guide, I had no problem uploading all 300-ish of my books into Audiobookshelf, with no misses or mismatches.

Of course, this all presupposes that you’ve got some DRM-free audiobooks. There are plenty of sources where you can get books free of charge—like Librivox, for example. If you’re using pay sites like Audible, you’ll want to actually log in to your library via a web browser and download each audiobook locally; this will give you a pile of files in .AAX format or something similar—which leads to a significant caveat.

The DRM elephant in the room

While books that come on audio CDs don’t have DRM embedded in them, files downloaded from Audible or other for-pay sources often do. Audiobookshelf won’t play books with DRM, which means you need a method of stripping that DRM out.

Unfortunately, here’s where we run into a problem: removing DRM from your audiobooks is not universally legal. “In the US, the law against ‘circumventing’ effective DRM has no personal-use exemption. In Europe, it varies by country,” explained the Electronic Frontier Foundation’s Competition and IP Litigation Director Mitch Stoltz when Ars reached out for advice. “That’s as silly as it sounds—stripping DRM from one’s own copy of an audiobook in order to listen to it privately through different software doesn’t threaten the author or publisher, except that it makes it harder for them to charge you twice for the same audiobook. It’s another example of how anti-circumvention laws interfere with consumers’ rights of ownership over the things they buy.”

And that means you’re kind of on your own for this step. Should you live in a jurisdiction where DRM removal from audiobooks for personal use is legal—which includes some but not all European countries—then sites like this one can assist in the process; for the rest of us, the only advice I can give is to simply proceed in a legal manner and use DRM-free audiobooks to start with.

Playing things

Once you’ve got Audiobookshelf set up and your DRM-free books stuffed into it, the last piece of the puzzle is an app to actually listen to books with. There is an official Audiobookshelf app, and if you’re an Android user you can grab it right here. The iOS app is perpetually stuck in beta and requires Test Flight, but there are third-party alternatives.

Personally, I’ve been using Plappa, and I’ve found it to be not just perfectly acceptable, but also more responsive and less prone to crashing than Apple’s own Books app (not to mention there’s no annoying in-app audiobook store page always trying to get in my face!).

Administrating things

Audiobookshelf itself has plenty of tunable options for the home system administrator who just can’t leave well enough alone; I’ve found most of the defaults are exactly what I want, but there’s tons of stuff to tweak if you want to do the tweaking.

Notably, Audiobookshelf supports multiple libraries if you want more organizational options. It has accounts you can set up for different listeners, logging options, notification options, RSS support, and a whole mess of other things I honestly haven’t even looked at yet. The good news for me is that you don’t have to look at any of that stuff if you don’t want to—Audiobookshelf is set up to be workable right out of the box.

But what if I’m not home?

Sharper readers might already have spotted a major problem with self-hosting audiobooks on one’s LAN: How do you listen when you’re not on the LAN?

This is probably worth another article, but the way I’m tackling this particular problem is with a local instance of Wireguard and a VPN profile on my mobile devices. When I’m out and about or in the car or whatever, I can tap the “VPN” shortcut on my iOS home screen, and boom—Plappa is now able to see Audiobookshelf, and streaming works just as well as it does at home.

One potential concern for doing this is cellular data usage, but this fear seems minor. The biggest audiobook I’ve got is a cool multicast recording of Frank Herbert’s Dune, which weighs in at about 2.4GB—so, the most data I’m going to transfer even for my biggest audiobook is 2.4GB max, and that’d only be if I listened to all hillion-jillion hours of Dune at the same time. And depending on the app you’re using for playback, you’ll likely also have the option to download the books to your device and listen to them locally, without streaming. (This is true for Plappa, at least.)

Self-hosting happiness achieved

I glossed over a lot of the setup steps to keep this a relatively short piece, but even so, getting Audiobookshelf going is a relatively simple self-hosting task, as self-hosting tasks go.

We also haven’t talked about Audiobookshelf’s other major feature: podcast hosting. I’m not a big podcast kind of guy (I tend to prefer audiobooks if I have time to listen to something), but Audiobookshelf is also (purportedly) great for hosting a giant pile of podcasts. If those are your jam, then that’s another point for Audiobookshelf.

I can’t vouch for the podcasting bits, but I can say that it’s gratifying to have solved a problem—especially one that was driving my wife crazy, and any day I can solve a problem for her via nerdery and server-wrangling is a good day. At least as of right now, the Audible app on her phone remains nonfunctional for reasons that are beyond me, but with luck—and a bit of ongoing care and maintenance for the server in the closet where this stuff all lives now—neither of us will ever have to deal with that app again.

The same day Trump bought a Tesla, automaker moved to disrupt trade war


Tesla hopes to slow down Trump’s tit-for-tat tariffs amid financial woes.

Elon Musk’s Tesla is waving a red flag, warning that Donald Trump’s trade war risks dooming US electric vehicle makers, triggering job losses, and hurting the economy.

In an unsigned letter to the US Trade Representative (USTR), Tesla cautioned that Trump’s tariffs could increase costs of manufacturing EVs in the US and forecast that any retaliatory tariffs from other nations could spike costs of exports.

“Tesla supports a robust and thorough process” to “address unfair trade practices,” but only those “which, in the process, do not inadvertently harm US companies,” the letter said.

The carmaker recommended that the USTR—in its ongoing review of unfair trade practices and investigation into harms of non-reciprocal trade agreements—”consider the downstream impacts of certain proposed actions taken to address unfair trade practices.”

According to Tesla, the current process to address unfair trade threatens to harm its more than 70,000 employees, and more broadly could trigger job losses and revenue dips in the US auto industry. It could also disrupt supply chains, as Tesla claims that even its best efforts prove it would be “impossible” to source all parts from the US currently.

“Even with aggressive localization of the supply chain, certain parts and components are difficult or impossible to source within the United States,” the letter said, asking the USTR to “evaluate domestic supply chain limitations.”

If left unchanged, the process could make the US less competitive in global auto markets, Tesla warned, recommending that the “USTR should investigate ways to avoid these pitfalls in future actions.”

Moving forward, Tesla recommends that the USTR “take into account” how the trade war could hurt US exporters, as “US exporters are inherently exposed to disproportionate impacts when other countries respond to US trade actions.”

In the letter, Tesla appears to suggest that Trump’s tariffs were rushed, suggesting that “US companies will benefit from a phased approach that enables them to prepare accordingly and ensure appropriate supply chain and compliance measures are taken.”

Tesla was not alone in submitting comments to the USTR. So far, hundreds of companies have chimed in, many hoping to push back on Trump’s aggressive tariffs regime.

Among them was a trade group representing major foreign automakers like BMW, Honda, and Toyota—Autos Drive America—which agreed with Tesla that the USTR should slow Trump down and require considerations about long-term impacts of sudden actions to address unfair trade. They similarly warned that imposing “broad-based tariffs will disrupt production at US assembly plants,” Reuters reported.

“Automakers cannot shift their supply chains overnight, and cost increases will inevitably lead to some combination of higher consumer prices, fewer models offered to consumers and shut-down US production lines, leading to potential job losses across the supply chain,” the group said.

Disrupting Trump trade war may be tough

Last week, Trump’s 25 percent tariffs on Canada and Mexico took effect, likely frustrating Tesla, which relies on a small parts manufacturer in Canada, Laval Tool, to source parts for the already costly molds for its Cybertrucks. Those tariffs threatened to spike costs beyond the current rate of nearly $500,000 per mold at a time when the Cybertruck hasn’t been selling well, InsideEVs reported. And for Tesla, Trump’s China tariffs may hit even harder, as China is Tesla’s second biggest market.

On the day that those tariffs kicked in, the head of the Alliance for Automotive Innovation—which represents all the major US automakers, except Tesla—John Bozzella warned that “all automakers will be impacted by these tariffs on Canada and Mexico,” Reuters reported. He joined others predicting price hikes on cars coming soon, perhaps as high as 25 percent.

Tesla’s letter to the USTR is notably unsigned, despite CEO Musk’s close allyship with Trump as a senior advisor in his administration—suggesting Musk may be hesitant to directly criticize Trump’s trade war or his opposition to EVs.

Many have questioned how long Musk’s friendship with Trump can possibly last, given their strong personalities and seeming unwillingness to bend to critics. At the beginning of this administration, Musk seemed unafraid to question Trump despite teaming up with him. Perhaps most notably, Trump’s team was supposedly “furious” after Musk trashed Trump’s $500 billion “Stargate” project with OpenAI, Politico reported, which Trump had hyped as “tremendous” and “monumental.”

“It’s clear he has abused the proximity to the president,” a Trump ally granted anonymity told Politico. “The problem is the president doesn’t have any leverage over him and Elon gives zero fucks.”

Officially, Trump downplayed Musk’s public criticism of his major announcement, seeming to understand that Musk views OpenAI CEO Sam Altman—whom Musk is suing for making a “fool” out of him—as an enemy.

“He hates one of the people in the deal,” Trump told a reporter who asked if Musk’s comments had bothered him, confirming, “it doesn’t.”

Despite a long history of harsh comments about EVs, Trump has recently hyped Tesla cars, which Tesla noted in its letter to the USTR, further its mission “to accelerate the world’s transition to sustainable energy.” The BBC noted Tesla’s letter was sent the same day that Trump hosted a White House event where the president vowed to purchase a Tesla in defiance of Tesla boycotts and protests that some believe are driving a steep Tesla stock fall and even degrading the price of used Teslas. In a Truth Social post, Trump claimed that he was buying a Tesla to support “one of the World’s great automakers” and “Elon’s ‘baby,'” alleging that protests and boycotts were somehow illegal.

The Hill suggested that their friendship isn’t likely to end soon, even though Trump has supposedly complained in private about taunts suggesting that Musk is really the president or somehow pulling the strings, The Independent reported.

Musk may be settling into a good dynamic with Trump after spending ample time at the president’s side, reportedly even joining meetings and sensitive calls. Or perhaps Musk is giving Trump space to call the shots, after Musk’s Department of Government Efficiency’s aggressive cuts at federal agencies sparked backlash that finally pushed Trump to rein in Musk’s power a little.

Musk’s proximity to Trump was predicted to be a boon to his businesses, but Tesla has been stuck in a slump that seemingly some Trump allies think Trump might fear makes him look weak, The New Republic reported. But Trump has made tariffs the core of his trade policy, hoping aggressive taxes will force more industry into the US, and it’s hard to see how Musk could easily influence him to shift gears.

In Tesla’s letter, the automaker told the USTR that it was “essential to support US manufacturing jobs” by ensuring that cost-prohibitive tariffs or other import restrictions don’t disrupt critical auto industry supply chains. For Tesla, the stakes couldn’t be higher, as the company reminded the USTR that “Tesla was ranked as the world leader in the transition to vehicle electrification,” manufacturing “the best-selling car in the world (EV or otherwise).”

“Tesla’s US facilities support over 70,000 employees and are responsible for billions of dollars of US investment and economic activity each year,” Tesla’s letter said.

Scoop: Origami measuring spoon incites fury after 9 years of Kickstarter delay hell


The curious case of the missing Kickstarter spoons.

An attention-grabbing Kickstarter campaign attempting to reinvent the measuring spoon has turned into a mad, mad, mad, mad world for backers after years of broken promises and thousands of missing spoons.

The mind-boggling design for the measuring spoon first wowed the Internet in 2016 after a video promoting the Kickstarter campaign went viral and spawned widespread media coverage fawning over the unique design.

Known as Polygons, the three-in-one origami measuring spoons have a flat design that can be easily folded into common teaspoon and tablespoon measurements. “Regular spoons are so 3000 BC,” a tagline on the project’s website joked.

For gadget geeks, it’s a neat example of thinking outside of the box, and fans found it appealing to potentially replace a drawer full of spoons with a more futuristic-looking compact tool. Most backers signed up for a single set, paying $8–$12 each, while hundreds wanted up to 25 sets, a handful ordered 50, and just one backer signed up for 100. Delivery was initially promised by 2017, supposedly shipping to anywhere in the world.

But it’s been about nine years since more than 30,000 backers flocked to the Kickstarter campaign—raising more than $1 million and eclipsing Polygons’ $10,000 goal. And not only have more than a third of the backers not received their spoons, but now, after years of updates claiming that the spoons had been shipped, some backers began to wonder if the entire campaign might be a fraud. They could see that Polygons are currently being sold on social media and suspected that the maker might be abusing backers’ funds to chase profits, seemingly without ever seriously intending to fulfill their orders.

One Kickstarter backer, Caskey Hunsader, told Ars that he started doubting if the spoon’s designer—an inventor from India, Rahul Agarwal—was even a real person.

Ars reached out to verify Agarwal’s design background. We confirmed that, yes, Agarwal is a real designer, and, yes, he believes there is a method to the madness when it comes to his Kickstarter campaign, which he said was never intended to be a scam or fraud and is currently shipping spoons to backers. He forecasted that 2025 is likely the year that backers’ wait will finally end.

But as thousands of complaints on the Kickstarter attest, backers have heard that one before. It’s been two years since the last official update was posted, which only promised updates that never came and did not confirm that shipments were back on track. The prior update in 2022 promised that “the time has finally arrived when we begin bulk shipping to everyone!”

Hunsader told Ars that people seem mostly upset because of “bullshit,” which is widely referenced in the comments. And that anger is compounded “by the fact that they are producing, and they are selling this product, so they are operating their business using funds that all these people who were their first backers gave them, and we’re the ones who are not getting the product. I think that’s where the anger comes from.”

“It’s been years now, and [I’ve] watched as you promise good people their products and never deliver,” one commenter wrote. “Wherever you try… to sell [your] products, we will be there reminding them of the empty orders you left here.”

“Where is my item? I am beyond angry,” another fumed.

Those who did receive their spoons often comment on the substantial delays, but reviews are largely positive.

“Holy crap, folks,” a somewhat satisfied backer wrote. “Hell has frozen over. I finally got them (no BS).”

One backer was surprised to get twice as many spoons as expected, referencing an explanation blaming Chinese New Year for one delay and writing, “I can honestly say after 8 years… and an enormous amount of emails, I finally received my pledge. Except… I only ordered 3… and I received 6. I’d be inclined to ship some back to Polygons… bare with me… I’ll return them soon… I appreciate your patience… mebbe after Chinese New Years 2033…”

Agarwal agreed to meet with Ars, show us the spoon, and explain why backers still haven’t gotten their deliveries when the spoon appears widely available to purchase online.

Failing prototypes and unusable cheap knockoffs

As a designer, Agarwal is clearly a perfectionist. He was just a student when he had the idea for Polygons in 2014, winning design awards and garnering interest that encouraged him to find a way to manufacture the spoons. He felt eager to see people using them.

Agarwal told Ars that before he launched the Kickstarter, he had prototypes made in China that were about 85 percent of the quality that he and his collaborators at InventIndia required. Anticipating that the quality would be fully there soon, Agarwal launched the Kickstarter, along with marketing efforts that Agarwal said had to be squashed due to unexpectedly high interest in the spoons.

This is when things started spiraling, as Agarwal had to switch manufacturers five times, with each partner crashing into new walls trying to execute the novel product.

Once the Kickstarter hit a million dollars, though, Agarwal committed to following through on launching the product. Eventually, cheap knockoff versions began appearing online on major retail sites like Walmart and Amazon toward the end of 2024. Because Agarwal has patents and trademarks for his design, he can get the knockoffs taken down, but they proved an important point that Agarwal had learned the hard way: that his design, while appearing simplistic, was incredibly hard to pull off.

Ars handled both a legitimate Polygons spoon and a cheap knockoff. The knockoff was a flimsy, unusable slab of rubber dotted with magnets; the companies aping Agarwal’s idea are seemingly unable to replicate the manufacturing process that Agarwal has spent years perfecting to finally be able to widely ship Polygons today.

On the other hand, Agarwal’s spoon is sturdy, uses food-grade materials, and worked just as well measuring wet and dry ingredients during an Ars test. A silicon hinge connects 19 separate plastic pieces and ensures that magnets neatly snap along indented lines indicating if the measurement is a quarter, half, or whole teaspoon or tablespoon. It took Agarwal two and a half years to finalize the design while working with InventIndia, a leading product development firm in India. Prototyping required making special molds that took a month each to iterate rather than using a 3D-printing shortcut whereby multiple prototypes could be made in a day, which Agarwal said he’d initially anticipated could be possible.

Around the time that the prototyping process concluded, Agarwal noted, COVID hit, and supply chains were disrupted, causing production setbacks. Once production could resume, costs became a factor, as estimates used to set Kickstarter backer awards were based on the early failed Chinese prototype, and the costs of producing a functioning spoon were much higher. Over time, shipping costs also rose.

As Kickstarter funds dwindled, there was no going back, so Agarwal devised a plan to sell the spoons for double the price ($25–$30 a set) by marketing them on social media, explaining this in a note to backers posted on the Polygons site. Those sales would fund ongoing manufacturing, allowing profits to be recycled so that Kickstarter backers could gradually receive shipments dependent on social media sales volumes. Orders from anyone who paid extra for expedited shipping are prioritized.

It’s a math problem at this point, with more funding needed to scale. But Agarwal told Ars that sales on Shopify and TikTok Shop have increased each quarter, most recently selling 30,000 units on TikTok, which allowed Polygons to take out a bigger line of credit to fund more manufacturing. He also brought in a more experienced partner to focus on the business side while he optimizes production.

Agarwal told Ars that he understands trust has been broken with many Kickstarter backers, considering that totally fair. While about 38 percent of backers’ orders still need filling, he predicts that all backers could get their orders within the next six to eight months as Polygons becomes better resourced, but that still depends on social media sales.

Agarwal met Ars after attending a housewares show in Chicago, where he shopped the spoons with retailers who may also help scale the product in the coming years. He anticipates that as the business scales, the cost of the spoons will come back down. And he may even be able to move onto executing other product designs that have been on the backburner as he attempts to work his way out of the Kickstarter corner he backed himself into while obsessing over his first design.

Kickstarter problem goes beyond Polygons

Hunsader told Ars there’s a big difference “in a lie versus bad management,” suggesting that as a business owner who has managed Kickstarter campaigns, he thinks more transparency likely could’ve spared Polygons a lot of angry comments.

“I am not sitting here with a dart board with [Agarwal’s] face on it, being like, when am I going to get my damn spoons?” Hunsader joked. But the campaign’s Kickstarter messaging left many backers feeling like Polygons took backers’ money and ran, Hunsader said.

Unlike people who saw the spoons going viral on social media, Hunsader discovered Polygons just by scrolling on Kickstarter. As a fan of geeky gadgets, he used to regularly support campaigns, but his experience supporting Polygons and monitoring other cases of problematic Kickstarters have made him more hesitant to use the platform without more safeguards for backers.

“It’s not specifically a Polygons problem,” Hunsader told Ars. “The whole Kickstarter thing needs maybe just more protections in place.”

Kickstarter did not respond to Ars’ request to comment. But Kickstarter’s “accountability” policy makes clear that creators “put their reputation at risk” launching campaigns and are ultimately responsible for following through on backer promises. Kickstarter doesn’t issue refunds or guarantee projects, only providing limited support when backers report “suspicious activity.”

Redditors have flagged “shitty” Kickstarter campaigns since 2012, three years after the site’s founding, and the National Association of Attorneys General—which represents US state attorneys general—suggested in 2019 that disgruntled crowdfunding backers were increasingly turning to consumer protection laws to fight alleged fraud.

In 2015, an independent analysis by the University of Pennsylvania estimated that 9 percent of Kickstarter projects didn’t fulfill their rewards. More recently, it appeared that figure had doubled, as Fortune reported last year that an internal Kickstarter estimate put “the amount of revenue that comes from fraudulent projects as high as 18 percent.” A spokesperson disputed that estimate and told Fortune that the platform employs “extensive” measures to detect fraud.

Agarwal told Ars that he thinks it’s uncommon for a campaign to continue fulfilling backer rewards after eight years of setbacks. It would be easier to just shut down and walk away, and Kickstarter likely would not have penalized him for it. While the Kickstarter campaign allowed him to reach his dream of seeing people using his novel measuring spoon in the real world, it’s been bittersweet that the campaign has dragged out so long and kept the spoons out of the hands of his earliest supporters, he told Ars.

Hunsader told Ars that he hopes the Polygons story serves as a “cautionary tale” for both backers and creators who bite off more than they can chew when launching a Kickstarter campaign. He knows that designers like Agarwal can take a reputational hit.

“I don’t want to make somebody who has big dreams not want to dream, but you also, when you’re dealing with things like manufacturing technology, have to be realistic about what is and is not accomplishable,” Hunsader said.

Polygons collaborators at InventIndia told Ars that Agarwal is “dedicated and hard-working,” describing him as “someone deeply committed to delivering a product that meets the highest standards” and whose intentions have “always” been to “ship a perfect product.”

Agarwal’s team connected with Hunsader to schedule his Kickstarter reward shipment on Friday. Hunsader told Ars he doesn’t really care if it takes another nine years. It’s just a spoon, and “there are bigger fish to fry.”

“Listen, I can buy that narrative that he was somebody who got totally overwhelmed but handled it in the worst possible way ever,” Hunsader said.

He plans to continue patiently waiting for his spoons.

This story was updated on March 14 to update information on the Polygons Kickstarter campaign.

the-wheel-of-time-is-back-for-season-three,-and-so-are-our-weekly-recaps

The Wheel of Time is back for season three, and so are our weekly recaps

Andrew Cunningham and Lee Hutchinson have spent decades of their lives with Robert Jordan and Brandon Sanderson’s Wheel of Time books, and they previously brought that knowledge to bear as they recapped each first season episode and second season episode of Amazon’s WoT TV series. Now we’re back in the saddle for season three—along with insights, jokes, and the occasional wild theory.

These recaps won’t cover every element of every episode, but they will contain major spoilers for the show and the book series. We’ll do our best to not spoil major future events from the books, but there’s always the danger that something might slip out. If you want to stay completely unspoiled and haven’t read the books, these recaps aren’t for you.

New episodes of The Wheel of Time season three will be posted for Amazon Prime subscribers every Thursday. This write-up covers the entire three-episode season premiere, which was released on March 13.

Lee: Welcome back! Holy crap, has it only been 18 months since we left our broken and battered heroes standing in tableaux, with the sign of the Dragon flaming above Falme? Because it feels like it’s been about ten thousand years.

Andrew: Yeah, I’m not saying I want to return to the days when every drama on TV had 26 hour-long episodes per season, but when you’re doing one eight-episode run every year-and-a-half-to-two-years, you really feel those gaps. And maybe it’s just [waves arms vaguely at The World], but I am genuinely happy to have this show back.

This season’s premiere simply whips, balancing big action set-pieces and smaller character moments in between. But the whole production seems to be hitting a confident stride. The cast has gelled; they know what book stuff they’re choosing to adapt and what they’re going to skip. I’m sure there will still be grumbles, but the show does finally feel like it’s become its own thing.

Lee: Oh yeah. The first episode hits the ground running, with explosions and blood and stolen ter’angreal. And we’ve got more than one episode to talk about—the gods of production at Amazon have given us a truly gigantic three-episode premiere, with each episode lasting more than an hour. Our content cup runneth over!

Trying to straight-up recap three hours of TV isn’t going to happen in the space we have available, so we’ll probably bounce around a bit. What I wanted to talk about first was exactly what you mentioned: unlike seasons one and two, this time, the show seems to have found itself and locked right in. To me, it feels kind of like Star Trek: The Next Generation’s third season versus its first two.

Andrew: That’s a good point of comparison. I feel like a lot of TV shows fall into one of two buckets: either it starts with a great first season and gradually falls off, or it gets off to a rocky start and finds itself over time. Fewer shows get to take the second path because a “show with a rocky start” often becomes a “canceled show,” but they can be more satisfying to watch.

The one Big Overarching Plot Thing to know for book readers is that they’re basically doing book 4 (The Shadow Rising) this season, with other odds and ends tucked in. So even if it gets canceled after this, at least they will have gotten to do what I think is probably the series’ high point.

Lee: Yep, we find out in our very first episode this season that we’re going to be heading to the Aiel Waste rather than the southern city of Tear, which is a significant re-ordering of events from the books. But unlike some of the previous seasons’ changes that feel like they were forced upon the show by outside factors (COVID, actors leaving, and so on), this one feels like it serves a genuine narrative purpose. Rand is reciting the Prophesies of the Dragon to himself and he knows he needs the “People of the Dragon” to guarantee success in Tear, and while he’s not exactly sure who the “People of the Dragon” might be, it’s obvious that Rand has no army as of yet. Maybe the Aiel can help?

Rand is doing all of this because both the angel and the devil on Rand’s shoulders—that’s the Aes Sedai Moiraine Damodred with cute blue angel wings and the Forsaken Lanfear in fancy black leather BDSM gear—want him wielding Callandor, The Sword That is Not a Sword (as poor Mat Cauthon explains in the Old Tongue). This powerful sa’angreal is located in the heart of the Stone of Tear (it’s the sword in the stone, get it?!), and its removal from the Stone is a major prophetic sign that the Dragon has indeed come again.

Book three is dedicated to showing how all that happens—but, like you said, we’re not in book three anymore. We’re gonna eat our book 4 dessert before our book 3 broccoli!

Andrew: I like book 4 a lot (and I’d include 5 and 6 here too) because I think it’s when Robert Jordan was doing his best work balancing his worldbuilding and politicking with the early books’ action-adventure stuff, and including multiple character perspectives without spreading the story so thin that it could barely move forward. Book 3 was a stepping stone to this because the first two books had mainly been Rand’s, and we spend almost no time in Rand’s head in book 3. But you can’t do that in a TV show! So they’re mixing it up. Good! I am completely OK with this.

Lee:What did you think of Queen Morgase’s flashback introduction where we see how she won the Lion Throne of Andor (flanked by a pair of giant lions that I’m pretty sure came straight from Pier One Imports)? It certainly seemed a bit… evil.

Andrew: One of the bigger swerves that the show has taken with an established book character, I think! And well before she can claim to have been under the control of a Forsaken. (The other swerves I want to keep tabs on: Moiraine actively making frenemies with Lanfear to direct Rand, and Lan being the kind of guy who would ask Rand if he “wants to talk about it” when Rand is struggling emotionally. That one broke my brain, the books would be half as long as they are if men could openly talk to literally any other men about their states of mind.)

But I am totally willing to accept that Morgase change because the alternative is chapters and chapters of people yapping about consolidating political support and daes dae’mar and on and on. Bo-ring!

But speaking of Morgase and Forsaken, we’re starting to spend a little time with all the new baddies who got released at the end of last season. How do you feel about the ones we’ve met so far? I know we were generally supportive of the fact that the show is just choosing to have fewer of them in the first place.

Lee: Hah, I loved the contrast with Book Lan, who appears to only be capable of feeling stereotypically manly feelings (like rage, shame, or the German word for when duty is heavier than a mountain, which I’m pretty sure is something like “Bergpflichtenschwerengesellschaften”). It continues to feel like all of our main characters have grown up significantly from their portrayals on the page—they have sex, they use their words effectively, and they emotionally support each other like real people do in real life. I’m very much here for that particular change.

But yes, the Forsaken. We know from season two that we’re going to be seeing fewer than in the books—I believe we’ve got eight of them to deal with, and we meet almost all of them in our three-episode opening blast. I’m very much enjoying Moghedien’s portrayal by Laia Costa, but of course Lanfear is stealing the show and chewing all the scenery. It will be fascinating to see how the show lets the others loose—we know from the books that every one of the Forsaken has a role to play (including one specific Forsaken whose existence has yet to be confirmed but who figures heavily into Rand learning more about how the One Power works), and while some of those roles can be dropped without impacting the story, several definitely cannot.

And although Elaida isn’t exactly a Forsaken, it was awesome to see Shohreh Aghdashloo bombing around the White Tower looking fabulous as hell. Chrisjen Avasarala would be proud.

Andrew: Maybe I’m exaggerating but I think Shohreh Aghdashloo’s actual voice goes deeper than Hammed Animashaun’s lowered-in-post-production voice for Loial. It’s an incredible instrument.

Meeting Morgase in these early episodes means we also meet Gaebril, and the show only fakes viewers out for a few scenes before revealing what book-readers know: that he’s the Forsaken Rahvin. But I really love how these scenes play, particularly his with Elayne. After one weird, brief look, they fall into a completely convincing chummy, comfortable stepdad-stepdaughter relationship, and right after that, you find out that, oops, nope, he’s been there for like 15 minutes and has successfully One Power’d everyone into believing he’s been in their lives for decades.

It’s something that we’re mostly told-not-shown in the books, and it really sells how powerful and amoral and manipulative all these characters are. Trust is extremely hard to come by in Randland, and this is why.

Lee: I very much liked the way Gaebril’s/Rahvin’s crazy compulsion comes off, and I also like the way Nuno Lopes is playing Gaebril. He seems perhaps a little bumbling, and perhaps a little self-effacing—truly, a lovable uncle kind of guy. The kind of guy who would say “thank you” to a servant and smile at children playing. All while, you know, plotting the downfall of the kingdom. In what is becoming a refrain, it’s a fun change from the books.

And along the lines of unassuming folks, we get our first look at a Gray Man and the hella creepy mechanism by which they’re created. I can’t recall in the books if Moghedien is explicitly mentioned as being able to fashion the things, but she definitely can in the show! (And it looks uncomfortable as hell. “Never accept an agreement that involves the forcible removal of one’s soul” is an axiom I try to live by.)

Andrew: It’s just one of quite a few book things that these first few episodes speedrun. Mat has weird voices in his head and speaks in tongues! Egwene and Elayne pass the Accepted test! (Having spent most of an episode on Nynaeve’s Accepted test last season, the show yada-yadas this a bit, showing us just a snippet of Egwene’s Rand-related trials and none of Elayne’s test at all.) Elayne’s brothers Gawyn and Galad show up, and everyone thinks they’re very hot, and Mat kicks their asses! The Black Ajah reveals itself in explosive fashion, and Siuan can only trust Elayne and Nynaeve to try and root them out! Min is here! Elayne and Aviendha kiss, making more of the books’ homosexual subtext into actual text! But for the rest of the season, we split the party in basically three ways: Rand, Egwene, Moiraine and company head with Aviendha to the Waste, so that Rand can make allies of the Aiel. Perrin and a few companions head home to the Two Rivers and find that things are not as they left them. Nynaeve and Elayne are both dealing with White Tower intrigue. There are other threads, but I think this sets up most of what we’ll be paying attention to this season.

As we try to wind down this talk about three very busy episodes, is there anything you aren’t currently vibing with? I feel like Josha Stradowski’s Rand is getting lost in the shuffle a bit, despite this nominally being his story.

Lee: I agree about Rand—but, hey, the same de-centering of Rand happened in the books, so at least there is symmetry. I think the things I’m not vibing with are at this point just personal dislikes. The sets still feel cheap. The costumes are great, but the Great Serpent rings are still ludicrously large and impractical.

I’m overjoyed the show is unafraid to shine a spotlight on queer characters, and I’m also desperately glad that we aren’t being held hostage by Robert Jordan’s kinks—like, we haven’t seen a single Novice or Accepted get spanked, women don’t peel off their tops in private meetings to prove that they’re women, and rather than titillation or weirdly uncomfortable innuendo, these characters are just straight-up screwing. (The Amyrlin even notes that she’s not sure the Novices “will ever recover” after Gawyn and Galad come to—and all over—town.)

If I had to pick a moment that I enjoyed the most out of the premiere, it would probably be the entire first episode—which in spite of its length kept me riveted the entire time. I love the momentum, the feeling of finally getting the show that I’d always hoped we might get rather than the feeling of having to settle.

How about you? Dislikes? Loves?

Andrew: Not a ton of dislikes, I am pretty in the tank for this at this point. But I do agree that some of the prop work is weird. The Horn of Valere in particular looks less like a legendary artifact and more like a decorative pitcher from a Crate & Barrel.

There were two particular scenes/moments that I really enjoyed. Rand and Perrin and Mat just hang out, as friends, for a while in the first episode, and it’s very charming. We’re told in the books constantly that these three boys are lifelong pals, but (to the point about Unavailable Men we were talking about earlier) we almost never get to see actual evidence of this, either because they’re physically split up or because they’re so wrapped up in their own stuff that they barely want to speak to each other.

I also really liked that brief moment in the first episode where a Black Ajah Aes Sedai’s Warder dies, and she’s like, “hell yeah, this feels awesome, this is making me horny because of how evil I am.” Sometimes you don’t want shades of gray—sometimes you just need some cartoonishly unambiguous villainy.

Lee: I thought the Black Ajah getting excited over death was just the right mix of of cartoonishness and actual-for-real creepiness, yeah. These people have sold their eternal souls to the Shadow, and it probably takes a certain type. (Though, as book readers know, there are some surprising Black Ajah reveals yet to be had!)

We close out our three-episode extravaganza with Mat having his famous stick fight with Zoolander-esque male models Gawyn and Galad, Liandrin and the Black Ajah setting up shop (and tying off some loose ends) in Tanchico, Perrin meeting Faile and Lord Luc in the Two Rivers, and Rand in the Aiel Waste, preparing to do—well, something important, one can be sure.

We’ll leave things here for now. Expect us back next Friday to talk about episode four, which, based on the preview trailers already showing up online, will involve a certain city in the desert, wherein deep secrets will be revealed.

Why SNES hardware is running faster than expected—and why it’s a problem


gotta go precisely the right speed

Cheap, unreliable ceramic APU resonators lead to “constant, pervasive, unavoidable” issues.

Sir, do you know how fast your SNES was going? Credit: Getty Images

Ideally, you’d expect any Super NES console—if properly maintained—to operate identically to any other Super NES unit ever made. Given the same base ROM file and the same set of precisely timed inputs, all those consoles should hopefully give the same gameplay output across individual hardware and across time.

The TASBot community relies on this kind of solid-state predictability when creating tool-assisted speedruns that can be executed with robotic precision on actual console hardware. But on the SNES in particular, the team has largely struggled to get emulated speedruns to sync up with demonstrated results on real consoles.

After significant research and testing on dozens of actual SNES units, the TASBot team now thinks that a cheap ceramic resonator used in the system’s Audio Processing Unit (APU) is to blame for much of this inconsistency. While Nintendo’s own documentation says the APU should run at a consistent rate of 24,576 Hz (and the associated Digital Signal Processor sample rate at a flat 32,000 Hz), in practice, that rate can vary just a bit based on heat, system age, and minor physical variations that develop in different console units over time.

Casual players would only notice this problem in the form of an almost imperceptibly higher pitch for in-game music and sounds. But for TASbot, Allan “dwangoAC” Cecil says this unreliable clock has become a “constant, pervasive, unavoidable” problem for getting frame-accurate consistency in hardware-verified speedruns.

Not to spec

Cecil says he first began to suspect the APU’s role in TASBot’s SNES problems back in 2016 when he broke open his own console to test it with an external frequency counter. He found that his APU ran just a bit faster than Nintendo’s specifications, an inconsistency that could cause the console to throw out unpredictable “lag frames” if and when the CPU and APU load cycles failed to line up in the expected manner. Those lag frames, in turn, are enough to “desynchronize” TASBot’s input on actual hardware from the results you’d see on a more controlled emulator.

Unlike the quartz crystals used in many electronics (including the SNES’s more consistent and differently timed CPU), the cheaper ceramic resonators in the SNES APU are “known to degrade over time,” as Cecil put it. Documentation for the resonators used in the APU also seems to suggest that excess heat may impact the clock cycle speed, meaning the APU might speed up a bit as a specific console heats up.

The TASBot team was not the first group to notice this kind of audio inconsistency in the SNES. In the early 2000s, some emulator developers found that certain late-era SNES games don’t run correctly when the emulator’s Digital Signal Processor (DSP) sample rate is set to the Nintendo-specified value of precisely 32,000 Hz (a number derived from the speed of the APU clock). Developers tested actual hardware at the time and found that the DSP was actually running at 32,040 Hz and that setting the emulated DSP to run at that specific rate suddenly fixed the misbehaving commercial games.

That small but necessary emulator tweak implies that “the original developers who wrote those games were using hardware that… must have been running slightly faster at that point,” Cecil told Ars. “Because if they had written directly to what the spec said, it may not have worked.”

Survey says…

While research and testing confirmed the existence of these APU variations, Cecil wanted to determine just how big the problem was across actual consoles today. To do that, he ran an informal online survey last month, cryptically warning his social media followers that “SNES consoles seem to be getting faster as they age.” He asked respondents to run a DSP clock measurement ROM on any working SNES hardware they had lying around and to rerun the test after the console had time to warm up.

After receiving 143 responses and crunching the numbers, Cecil said he was surprised to find that temperature seemed to have a minimal impact on measured DSP speed; the measurement only rose an insignificant 8 Hz on average between “cold” and “hot” readings on the same console. Cecil even put his own console in a freezer to see if the DSP clock rate would change as it thawed out and found only a 22 Hz difference as it warmed back up to room temperature.

Those heat effects paled in comparison to the natural clock variation across different consoles, though. The slowest and fastest DSPs in Cecil’s sample showed a clock difference of 234 Hz, or about 0.7 percent of the 32,000 Hz specification.

That difference is small enough that human players probably wouldn’t notice it directly; TASBot team member Total estimated it might amount to “at most maybe a second or two [of difference] over hours of gameplay.” Skilled speedrunners could notice small differences, though, if differing CPU and APU alignments cause “carefully memorized enemy pattern changes to something else” between runs, Cecil said.

For a frame-perfect tool-assisted speedrun, though, the clock variations between consoles could cause innumerable headaches. As TASBot team member Undisbeliever explained in his detailed analysis: “On one console this might take 0.126 frames to process the music-tick, on a different console it might take 0.127 frames. It might not seem like much but it is enough to potentially delay the start of song loading by 1 frame (depending on timing, lag and game-code).”

Cecil’s survey found variation across consoles was much higher than the effects of heat on any single console.

Cecil also said the survey-reported DSP clock speeds were also a bit higher than he expected, at an average rate of 32,078 Hz at room temperature. That’s quite a bit higher than both the 32,000 Hz spec set by Nintendo and the 32,040 Hz rate that emulator developers settled on after sampling actual hardware in 2003.

To some observers, this is evidence that SNES APUs originally produced in the ’90s have been speeding up slightly as they age and could continue to get faster in the coming years and decades. But Cecil says the historical data they have is too circumstantial to make such a claim for certain.

“We’re all a bunch of differently skilled geeks and nerds, and it’s in our nature to argue over what the results mean, which is fine,” Cecil said. “The only thing we can say with certainty is the statistical significance of the responses that show the current average DSP sample rate is 32,076 Hz, faster on average than the original specification. The rest of it is up to interpretation and a certain amount of educated guessing based on what we can glean.”

A first step

For the TASBot team, knowing just how much real SNES hardware timing can differ from dry specifications (and emulators) is an important step to getting more consistent results on real hardware. But that knowledge hasn’t completely solved their synchronization problems. Even when Cecil replaced the ceramic APU resonator in his Super NES with a more accurate quartz version (tuned precisely to match Nintendo’s written specification), the team “did not see perfect behavior like we expected,” he told Ars.

Beyond clock speed inconsistencies, Cecil explained to Ars that TASBot team testing has found an additional “jitter pattern” present in the APU sampling that “injects some variance in how long it takes to perform various actions” between runs. That leads to non-deterministic performance even on the same hardware, Cecil said, which means that “TASBot is likely to desync” after just a few minutes of play on most SNES games.

The order in which these components start when the SNES is reset can have a large impact on clock synchronization.

Extensive research from Rasteri suggests that these inconsistencies across same-console runs are likely caused by a “very non-deterministic reset circuit” that changes the specific startup order and timing for a console’s individual components every time it’s powered on. That leads to essentially “infinite possibilities” for the relative place where the CPU and APU clocks start in their “synchronization cycle” for each fresh run, making it impossible to predict specifically where and when lag frames will appear, Rasteri wrote.

Cecil said these kind of “butterfly effect” timing issues make the Super NES “a surprisingly complicated console [that has] resisted our attempts to fully model it and coerce it into behaving consistently.” But he’s still hopeful that the team will “eventually find a way to restore an SNES to the behavior game developers expected based on the documentation they were provided without making invasive changes…”

In the end, though, Cecil seems to have developed an almost grudging respect for how the SNES’s odd architecture leads to such unpredictable operation in practice. “If you want to deliberately create a source of randomness and non-deterministic behavior, having two clock sources that spinloop independently against one another is a fantastic choice,” he said.

Crew-10 launches, finally clearing the way for Butch and Suni to fly home

A Falcon 9 rocket launched four astronauts safely into orbit on Friday evening, marking the official beginning of the Crew-10 mission to the International Space Station.

Although any crew launch into orbit is notable, this mission comes with an added bit of importance as its success clears the way for two NASA astronauts, Butch Wilmore and Suni Williams, to finally return home from space after a saga spanning nine months.

Friday’s launch came two days after an initial attempt was scrubbed on Wednesday evening. This was due to a hydraulic issue with the ground systems that handle the Falcon 9 rocket at Launch Complex 39A in Florida.

There were no technical issues on Friday, and with clear skies NASA astronauts Anne McClain and Nichole Ayers, Japanese astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov rocketed smoothly into orbit.

If all goes well, the Crew Dragon spacecraft carrying the four astronauts will dock with the space station at 11: 30 pm ET on Saturday. They will spend about six months there.

A long, strange trip

Following their arrival at the space station, the members of Crew-10 will participate in a handover ceremony with the four astronauts of Crew-9, which includes Wilmore and Williams. This will clear the members of Crew 9 for departure from the station as early as next Wednesday, March 19, pending good weather in the waters surrounding Florida for splashdown of Dragon.

On MAIM and Superintelligence Strategy

Dan Hendrycks, Eric Schmidt and Alexandr Wang released an extensive paper titled Superintelligence Strategy. There is also an op-ed in Time that summarizes.

The major AI labs expect superintelligence to arrive soon. They might be wrong about that, but at minimum we need to take the possibility seriously.

At a minimum, the possibility of imminent superintelligence will be highly destabilizing. Even if you do not believe it represents an existential risk to humanity (and if so you are very wrong about that) the imminent development of superintelligence is an existential threat to the power of everyone not developing it.

Planning a realistic approach to that scenario is necessary.

What would it look like to take superintelligence seriously? What would it look like if everyone took superintelligence seriously, before it was developed?

The proposed regime here, Mutually Assured AI Malfunction (MAIM), relies on various assumptions in order to be both necessary and sufficient. If those assumptions did turn out to hold, it would be a very interesting, highly not crazy proposal.

  1. ASI (Artificial Superintelligence) is Dual Use.

  2. Three Proposed Interventions.

  3. The Shape of the Problems.

  4. Strategic Competition.

  5. Terrorism.

  6. Loss of Control.

  7. Existing Strategies.

  8. MAIM of the Game.

  9. Nonproliferation.

  10. Competitiveness.

  11. Laying Out Assumptions: Crazy or Crazy Enough To Work?.

  12. Don’t MAIM Me Bro.

ASI helps you do anything you want to do, which in context is often called ‘dual use.’

As in, AI is both a highly useful technology for both military and economic use. It can be used for, or can be an engine of, creation and also for destruction.

It can do both these things in the hands of humans, or on its own.

That means that America must stay competitive in AI, or even stay dominant in AI, both for our economic and our military survival.

The key players include not only states but also non-state actors.

Given what happens by default, what can we do to steer to a different outcome?

They propose three pillars.

Two are highly conventional and traditional. One is neither, in the context of AI.

First, the two conventional ones.

Essentially everyone can get behind Competitiveness, building up AI chips through domestic manufacturing. At least in principle. Trump called for us to end the Chips Act because he is under some strange delusions about how economics and physics work and thinks tariffs are how you fix everything (?), but he does endorse the goal.

Nonproliferation is more controversial but enjoys broad support. America already imposes export controls on AI chips and the proposed diffusion regulations would substantially tighten that regime. This is a deeply ordinary and obviously wise policy. There is a small extremist minority that flips out and calls proposals for ordinary enforcement of things like ‘a call for a global totalitarian surveillance state’ but such claims are rather Obvious Nonsense, entirely false and without merit, since they describe the existing policy regime in many sectors, not only in AI.

The big proposal here is Deterrence with Mutual Assured AI Malfunction (MAIM), as a system roughly akin to Mutually Assured Destruction (MAD) from nuclear weapons.

The theory is that if it is possible to detect and deter opposing attempts to developer superintelligence, the world can perhaps avoid developing superintelligence until we are ready for that milestone.

This chart of wicked problems in need of solving is offered. The ‘tame technical subproblems’ are not easy, but are likely solvable. The wicked problems are far harder.

Note that we are not doing that great a job on even the tame technical subproblems.

  1. Train AI systems to refuse harmful requests: We don’t have an AI system that cannot be jailbroken, even if it is closed weights and under full control, without crippling the mundane utility offered by the system.

  2. Prepare cyberattacks for AI datacenters: This is the one that is not obviously a net positive idea. Presumably this is being done in secret, but I have no knowledge of us doing anything here.

  3. Upgrade AI chip firmware to add geolocation functionality: We could presumably do this, but we haven’t done it.

  4. Patch known vulnerabilities in AI developers’ computer systems: I hope we are doing a decent job of this. However the full ‘tame’ problem is to do this across all systems, since AI will soon be able to automate attacks on all systems, exposing vulnerable legacy systems that often are tied to critical infrastructure. Security through obscurity is going to become a lot less effective.

  5. Design military drones: I do not get the sense we are doing a great job here, either in design or production, relative to its military importance.

  6. Economic strength: Improve AI performance in economically valuable tasks: We’re making rapid progress here, and it still feels like balls are dropped constantly.

  7. Loss of control: Research methods to make current AIs follow instructions: I mean yes we are doing that, although we should likely be investing 10x more. The problem is that our current methods to make this work won’t scale to superintelligence, with the good news being that we are largely aware of that.

They focus on three problems.

They don’t claim these are a complete taxonomy. At a sufficiently abstract level, we have a similar trio of threats to the ones OpenAI discusses in their philosophy document: Humans might do bad things on purpose (terrorism), the AI might do bad things we didn’t intend (loss of control), or locally good things could create bad combined effects (this is the general case of strategic competition, the paper narrowly focuses on state competition but I would generalize this to competition generally).

These problems interact. In particular, strategic competition is a likely key motivator for terrorism, and for risking or triggering a loss of control.

Note the term ‘meaningful’ in meaningful human control. If humans nominally have control, but in practice cannot exercise that control, humans still have lost control.

The paper focuses on the two most obvious strategic competition elements: Economic and military.

Economics is straightforward. If AI becomes capable of most or all labor, then how much inference you can do becomes a prime determinant of economic power, similar to what labor is today, even if there is no full strategic dominance.

Military is also straightforward. AI could enable military dominance through ‘superweapons,’ up to and including advanced drone swarms, new forms of EMP, decisive cyber weapons or things we aren’t even imagining. Sufficiently strong AI would presumably be able to upend nuclear deterrence.

If you are about to stare down superintelligence, you don’t know what you’ll face, but you know if you don’t act now, it could be too late. You are likely about to get outcompeted. It stands to reason countries might consider preventative action, up to and including outright war. We need to anticipate this possibility.

Strategic competition also feeds into the other two risks.

If you are facing strong strategic competition, either the way the paper envisioned at a national level, or competition at the corporate or personal level, from those employing superintelligence, you may have no choice but to either lose or deploy superintelligence yourself. And if everyone else is fully unleashing that superintelligence, can you afford not to do the same? How do humans stay in the loop or under meaningful control?

Distinctly from that fear, or perhaps in combination with it, if actions that are shaped like ‘terrorism’ dominate the strategic landscape, what then?

The term terrorism makes an assertion about what the goal of terrorism is. Often, yes, the goal is to instill fear, or to trigger a lashing out or other expensive response. But we’ve expanded the word ‘terrorism’ to include many other things, so that doesn’t have to be true.

In the cases of this ‘AI-enabled terrorism’ the goal mostly is not to instill fear. We are instead talking about using asymmetric weapons, to inflict as much damage as possible. The scale of the damage relatively unresourced actors can do will scale up.

We have to worry in particular about bioterrorism and cyberattacks on critical infrastructure – this essay chooses to not mention nuclear and radiological risks.

As always this question comes down to offense-defense balance and the scale (and probability) of potential harm. If everyone gets access to similarly powerful AI, what happens? Does the ‘good guy with an AI’ beat the ‘bad guy with an AI’? Does this happen in practice, despite the future being unevenly distributed, and thus much of critical infrastructure not having up-to-date defenses, and suffering from ‘patch lag’?

This is a cost-benefit analysis, including the costs of limiting proliferation. There are big costs in taking action to limit proliferation, even if you are confident it will ultimately work.

The question is, are there even larger costs to not doing so? That’s a fact question. I don’t know the extent to which future AI systems might enable catastrophic misuse, or how much damage that might cause. You don’t either.

We need to do our best to answer that question in advance, and if necessary to limit proliferation. If we want to do that limiting gracefully, with minimal economic costs and loss of freedom, that means laying the necessary groundwork now. The alternative is doing so decidedly ungracefully, or failing to do so at all.

The section on Loss of Control is excellent given its brevity. They cover three subsections.

  1. Erosion of control is similar to the concerns about gradual disempowerment. If anyone not maximally employing AI becomes uncompetitive, humans would rapidly find themselves handing control over voluntarily.

  2. Unleashed AI Agents are an obvious danger. Even a single sufficient capable rouge AI agent unleashed on the internet could cause no end of trouble, and there might be no reasonable way to undo this without massive economic costs we would not be willing to pay once it starts gathering resources and self-replicating. Even a single such superintelligent agent could mean irrevocable loss of control. As always, remember that people will absolutely be so stupid as to, and also some will want to do it, on purpose.

  3. Intelligence Recursion, traditionally called Recursive Self-Improvement (RSI), where smarter AI builds smarter AI builds smarter AI, perhaps extremely rapidly. This is exactly how one gets a strategic monopoly or dominant position, and is ‘the obvious thing to do,’ it’s tough not to do it.

They note explicitly that strategic competition, in the form of geopolitical competitive pressures, could easily make us highly tolerant of such risks, and therefore we could initiate such a path of RSI even if those involved thought the risk of loss of control was very high. I would note that this motivation also holds for corporations and others, not only nations, and again that some people would welcome a loss of control, and others will severely underestimate the risks, with varying levels of conscious intention.

What are our options?

They note three.

  1. There is the pure ‘hands-off’ or ‘YOLO’ strategy where we intentionally avoid any rules or restrictions whatsoever, on the theory that humans having the ability to collectively steer the future is bad, actually, and we should avoid it. This pure anarchism is a remarkably popular position among those who are loud on Twitter. As they note, from a national security standpoint, this is neither a credible nor a coherent strategy. I would add that from the standpoint of trying to ensure humanity survives, it is again neither credible nor coherent.

  2. Moratorium strategy. Perhaps we can pause development past some crucial threshold? That would be great if we could pull it off, but coordination is hard and the incentives make this even harder than usual, if states lack reliable verification mechanisms.

  3. Monopoly strategy. Try to get there first and exert a monopoly, perhaps via a ‘Manhattan Project’ style state program. They argue that it would be impossible to hide this program, and others would doubtless view it as a threat and respond with escalations and hostile countermeasures.

They offer this graph as an explanation for why they don’t like Monopoly strategy:

Certainly escalation and even war is one potential response to the monopoly strategy, but the assumption that it goes that way is based on China or others treating superintelligence as an existential strategic threat. They have to take the threat so seriously that they will risk war over it, for real.

Would they take it that seriously before it happens? I think this is very far from obvious. It takes a lot of conviction to risk everything over something like that. Historically, deterrence strikes are rare, even when they would have made strategic sense, and the situation was less speculative. Nor does a successful strike automatically lead to escalation.

That doesn’t mean that going down these paths is good or safe. Racing for superintelligence as quickly as possible, with no solution on how to control it, in a way that forces your rival to respond in kind when previously let’s face it they weren’t trying all that hard, does not seem like a wise thing to aim for or do. But I think the above chart is too pessimistic.

Instead they propose a Multipolar strategy, with the theory being that Deterrence with Mutual Assured AI Malfunction (MAIM), combined with strong nonproliferation and competitiveness, can hopefully sustain an equilibrium.

There are two importantly distinct claims here.

The first claim here is that a suboptimal form of MAIM is the default regime, that costs for training runs will balloon, thus they can only happen at large obvious facilities, and therefore there are a variety of escalations those involved can use to shut down AI programs, from sabotage up to outright missile attacks, and any one rival is sufficient to shut down an attempt.

The second claim is that it would be wise to pursue a more optimal form of MAIM as an intentional policy choice.

MAIM is trivially true, at least in the sense that MAD is still in effect, although the paper claims that sabotage means there are reliable options available well short of a widespread nuclear strike. Global thermonuclear war would presumably shut down everyone’s ASI projects, but it seems likely that launching missiles at a lot of data centers would lead to full scale war, perhaps even somewhat automatic nuclear war. Do we really think ‘kinetic escalation’ or sabotage can reliably work and also be limited to the AI realm? Are there real options short of that?

Yes, you could try to get someone to sabotage, or engage in a cyberattack. The paper authors think that between all the options available, many of which are hard to attribute or defend against, we should expect such an afford to work if it is well resourced, at least enough to delay progress on the order of months. I’m not sure I have even that confidence, and I worry that it won’t count for much. Human sabotage seems likely to become less effective over time, as AIs themselves take on more of the work and error checking. Cyberattacks similarly seem like they are going to get more difficult, especially once everyone involved is doing fully serious active defense and accepting real costs of doing so.

The suggestion here is to intentionally craft and scope out MAIM, to allow for limited escalations along a clear escalation ladder, such as putting data centers far away from population centers and making clear distinctions between acceptable projects and destabilizing ones, and implementing ‘AI-assisted inspections.’

Some actions of this type took place during the Cold War. Then there are other nations and groups with a history of doing the opposite, doing some combination of hiding their efforts, hardening the relevant targets and intentionally embedding military targets inside key civilian infrastructure and using ‘human shields.’

That’s the core idea. I’ll touch quickly on the other two parts of the plan, Nonproliferation and Competitiveness, then circle back to whether the core idea makes sense and what assumptions it is making. You can safety skip ahead to that.

They mention you can skip this, and indeed nothing here should surprise you.

In order for the regime of everyone holding back to make sense, there need to be a limited number of actors at the established capabilities frontier, and you need to keep that level of capability out of the hands of the true bad actors. AI chips would be treated, essentially, as if they were also WMD inputs.

Compute security is about ensuring that AI chips are allocated to legitimate actors for legitimate purposes. This echoes the export controls employed to limit the spread of fissile materials, chemical weapons, and biological agents.

Information security involves securing sensitive AI research and model weights that form the core intellectual assets of AI. Protecting these elements prevents unwarranted dissemination and malicious use, paralleling the measures taken to secure sensitive information in the context of WMDs.

They discuss various mechanisms for tracking chips, including geolocation and geofencing, remote attestation, networking restrictions and physical tamper resistance. Keeping a lockdown on frontier-level model weights also follows, and they offer various suggestions on information security.

Under AI Security (5.3) they claim that model-level safeguards can be made ‘significantly resistant to manipulation.’ In practice I am not yet convinced.

They offer a discussion in 5.3.2 of loss of control, including controlling an intelligence recursion (RSI). I am not impressed by what is on offer here in terms of it actually being sufficient, but if we had good answers that would be a case for moving forward, not for pursuing a solution like MAIM.

The question on competitiveness is not if but rather how. The section feels somewhat tacked on, they themselves mention you can skip this.

The suggestions under military and economy should be entirely uncontroversial.

The exception is ‘facilitate immigration for AI scientists,’ which seems like the most obvious thing in the world to do, but alas. What a massive unforced error.

The correct legal framework for AI and AI agents has been the subject of extended debate, which doubtless will continue. The proposed framework here is to impose upon AIs a duty of reasonable care to the public, another duty of care to the principle, and a duty not to lie. They propose to leave the rest to the market to decide.

The section is brief so they can’t cover everything, but as a taste to remind one that the rabbit holes run deep even when considering mundane situations: Missing here is which human or corporation bears liability for harms. If something goes wrong, who is to blame? The user? The developer or deployer? They also don’t discuss how to deal with other obligations under the law, and they mention the issue of mens rea but not how they propose to handle it.

They also don’t discuss what happens if an AI agent is unleashed and is outside of human control, whether or not doing so was intentional, other than encouraging other AIs to not transact with such an AI. And they don’t discuss to what extent an AI agent would be permitted to act as a legal representative of a human. Can they sign contracts? Make payments? When is the human bound, or unbound?

They explicitly defer discussion of potential AI rights, which is its own rabbit hole.

The final discussion here is on political stability, essentially by using AI to empower decision makers and filter information, and potentially doing redistribution in the wake of automation. This feels like gesturing at questions beyond the scope of the paper.

What would make deliberately pursuing MAIM as a strategy both necessary and sufficient?

What would make it, as they assert, the default situation?

Both are possible, but there are a good number of assumptions.

The most basic requirement is that it essentially requires common knowledge.

Everyone must ‘feel the superintelligence,’ and everyone must be confident that:

  1. At least one other major player feels the superintelligence.

  2. That another state will attempt to stop you via escalation, if you go for it.

  3. That such escalation would either succeed or escalate to total war.

If you don’t believe all of that, you don’t have MAIM, the same way you would not have had MAD.

Indeed, we have had many cases of nuclear proliferation, exactly because states including North Korea have correctly gambled that no one would escalate sufficiently to stop them. Our planetary track record of following through in even the most obvious of situations is highly spotty. Our track record of preemptive wars in other contexts is even worse, with numerous false negatives and also false positives.

Superintelligence is a lot murkier and uncertain in its definition, threshold and implications than a nuclear bomb. How confident are you that your rivals will be willing to pull the trigger? How confident do they need to be that this is it? Wouldn’t there be great temptation to be an ostrich, and pretend it wasn’t happening, or wasn’t that big a deal?

That goes together with the question of whether others can reliably identify an attempt to create superintelligence, and then whether they can successfully sabotage that effort with a limited escalation. Right now, no one is trying all that hard to hide or shield what they are up to, but that could change. Right now, the process requires very obvious concentrated data centers, but that also could change, especially if one was willing to sacrifice efficiency. And so on. If we want to preserve things as they are, we will have to do that deliberately.

The paper asserts states ‘would not stand idly by’ while another was on the ‘cusp of superintelligence.’ I don’t think we can assume that. They might not realize what is happening. They might not realize the implications. They might realize probabilistically but not be willing to move that far up the escalatory ladder or credibly threaten to do so. A central failure mode is that the threat is real but not believed.

It seems, at minimum, rather strange to assume MAIM is the default. Surely, various sabotage efforts could complicate things, but presumably things get backed up and it is not at all obvious that there is a limited-scope way to stop a large training run indefinitely. It’s not clear what a few months of sabotage buys you even if it works.

The proposal here is to actively engineer a stable MAIM situation, which if enacted improves your odds, but the rewards to secrecy and violating the deals are immense. Even they admit that MAIM is a ‘wicked problem’ that would be in an unstable, constantly evolving state in the best of times.

I’m not saying it cannot be done, or even that you shouldn’t try. It certainly seems important to have the ability to implement such a plan in your back pocket, to the greatest extent possible, if you don’t intentionally want to throw your steering wheel out the window. I’m saying that even with the buy-in of those involved, it is a heavy lift. And with those currently in power in America, the lift is now that much tougher.

All of this can easily seem several levels of rather absurd. One could indeed point to many reasons why this strategy could wind up being profoundly flawed, or that the situation might be structured so that this does not apply, or that there could end up being a better way.

The point is to start thinking about these questions now, in case this type of scenario does play out, and to consider under what conditions one would want to seek out such a solution and steer events in that direction. To develop options for doing so, in case we want to do that. And to use this as motivation to actually consider all the other ways things might play out, and take them all seriously, and ask how we can differentiate which world we are living in, including how we might move between those worlds.

Outbreak turns 30


Ars chats with epidemiologist Tara Smith about the film’s scientific accuracy and impact over 3 decades.

Back in 2020, when the COVID pandemic was still new, everyone was “sheltering in place” and bingeing films and television. Pandemic-related fare proved especially popular, including the 1995 medical disaster-thriller Outbreak, starring Dustin Hoffman. Chalk it up to morbid curiosity, which some researchers have suggested is an evolved response mechanism for dealing with threats by learning from imagined experiences. Outbreak turned 30 this week, making this the perfect time to revisit the film.

(Spoilers for Outbreak abound below.) 

Outbreak deals with the re-emergence of a deadly virus called Motaba, 28 years after it first appeared in an African jungle, infecting US soldiers and many others. The US military secretly destroyed the camp to conceal evidence of the virus, a project overseen by Major General Donald McClintock (Donald Sutherland) and Brigadier General William Ford (Morgan Freeman). When it re-emerges in Zaire decades later, a military doctor, Colonel Sam Daniels (Hoffman), takes a team to the afflicted village to investigate, only to find the entire town has died.

Daniels takes blood samples and realizes the villagers had been infected by a deadly new virus. But Ford shrugs off  Daniels’ concerns about a potential global spread, not wanting the truth to come out about the bombing of the village nearly 30 years ago. Daniels alerts his estranged ex-wife, Dr. Roberta “Robby” Keough, who works for the Centers for Disease Control and Prevention, about the virus, and she, too, is initially concerned.

Meanwhile, a local monkey is captured and brought to the US as an exotic pet. A smuggler named Jimbo (Patrick Dempsey)—who works at an animal testing facility—tries to sell the monkey to a pet shop owner named Rudy (Daniel Chodos) in the fictional town of Cedar Creek, California. The monkey bites Rudy. Unable to sell the monkey, Jimbo lets it loose in the woods and flies home to Boston. Both Jimbo and his girlfriend (who greets him at Logan Airport and passionately kisses a feverish Jimbo right before he collapses) die from the virus.

Naturally Keough hears about the Boston cases and realizes Daniels was right—the new virus has found its way to American soil. Initially she thinks there aren’t any other cases, but then Rudy’s demise comes to light, along with the death of a hospital technician who became infected after accidentally breaking a vial of Rudy’s blood during testing. When the virus strikes down a cinema filled with moviegoers, Daniels and Keough realize the virus has mutated and become airborne.

This time Ford and a reluctant McClintock can’t afford not to act as the bodies keep piling up.  The military declares martial law in the town as Daniels and his fellow scientists race to develop a cure, even as the nefarious McClintock schemes to bomb Cedar Creek to smithereens to contain the virus. The deaths of the residents strike him as a necessary cost to preserve his hopes of developing Motaba as a biological weapon; he dismisses them as “casualties of war.”

Outbreak ended up grossing nearly $190 million worldwide when it was released in March 1995, but critical reviews were mixed. Some loved the medical thriller aspects and quick pacing, while others dismissed it as shallow and improbable. Some of the biggest criticisms of the film came from scientists.

A mixed bag

“Honestly, the science, if you look at it broadly, is not awful,” Tara Smith, an epidemiologist at Kent State University in Ohio, told Ars. “They showed BSL-4 facilities and had a little description of the different levels that you work in. The protagonists respond to an outbreak, they take samples, they bring them back to the lab. They infect some cells, infect some animals, they do some microscopy, although it’s not clear that they’re actually doing electron microscopy, which would be needed to see the virus. But overall, the steps are right.”

Granted, there are plenty of things to nitpick. “There’s a lot of playfulness,” said Smith. “Kevin Spacey [who plays military doctor Lt. Col. Casey Schuler] takes out a fake virus tube and tosses it to Cuba Gooding Jr. [who plays another military doctor, Major Salt]. You don’t play in the BSL-4 laboratories. You just don’t. And a lab tech [who becomes infected] is spinning a centrifuge and doing other things at the same time. Then he opens up the centrifuge and just puts his hand in there and everything breaks. That’s how he gets exposed to the virus. I’ve used a centrifuge hundreds of times. You wait until everything is stopped to open it up. As a trained scientist, those are the things you are told over and over not to do. [The filmmakers] exploit those to drive the plot.”

One of the biggest scientific criticisms is the time compression: the virus multiplies in the body within an hour instead of days; Salt eventually synthesizes a cure in under a minute when this would normally take months; and Keough (who has been infected) recovers almost immediately after being injected with said cure. Smith also noted that scientists identify the two Motaba strains using electron micrographs rather than sequencing them, as would normally be required.

And that whole bit about the Motaba virus liquefying organs just isn’t a thing, according to Smith. “If you read The Hot Zone [Richard Preston’s bestselling 1994 nonfiction thriller], or watch Outbreak and take a shot every time you hear ‘liquefying,’ you would be dead by the end,” she said. “I don’t know how that trope got so established in the media, but you see it every time the Ebola comes up: people are bleeding from their eyes, they’re liquefying. That doesn’t happen. They’re horribly sick. It is an awful virus, but people don’t just melt.”

That said, “I think the biggest [scientific] issue with Outbreak was the whole airborne thing,” said Smith. “Realistically, viruses just don’t change transmission like that.”

Influencing public perceptions

According to Smith, Outbreak may have impacted public perceptions of the 2014–2016 Ebola outbreak—the largest yet seen—fueling widespread fear. “There were very serious people in The New York Times talking about Ebola potentially becoming airborne,” she said. “There was one study where scientists had aerosolized the virus on purpose and given it to pigs and the pigs got infected, which was treated as proof that Ebola could be airborne.”

“That idea that Ebola is super contagious and you can spread it by air—that really originates with Outbreak in 1995, because if you look at the science, it’s just not there,” Smith continued. “Ebola is not that easy to get unless you have close, personal, bodily-fluid-exchanging contact. But people certainly thought it was airborne in 2014–2015, and thought that Ebola was going to cause this huge outbreak in the United States. Of course, we just had a few select cases.”

Smith is currently working on a project that reviews various outbreak stories in popular media and their influence on public perception, particularly when it comes to the origins of those outbreaks. “Where does the virus, fungus, or bacteria come from?” said Smith. “So many films and TV series have used a lab leak origin, where something was made in the laboratory, it escapes, and causes a global pandemic. That’s an important narrative when we talk about the COVID pandemic, because so many people jumped on the lab leak bandwagon as an origin for that. In Outbreak it’s a natural virus, not a lab leak. I don’t think you’d see that if it were re-made today.”

Sam and Salt find the information they’re looking for. Warner Bros.

Outbreak is often unfavorably compared to another pandemic movie, 2011’s Contagion, of which Smith is naturally a fan. “Contagion is the gold standard [of pandemic movies],” said Smith. “Contagion was done in very close collaboration with a lot of scientists. One of the scientists in the movie is even named for [Columbia University epidemiologist] Ian Lipkin. Scientific accuracy was more important from the start. And there’s a bigger timeframe. These things happen in months rather than days. Even in Contagion, the vaccine was developed quicker than in the COVID pandemic, but at least it was a little bit more realistically done, scarily so when you think about the Jude Law character who was the blogger peddling fake cures—very similar to Ivermectin during the COVID pandemic.”

One might quibble with the science, but as entertainment, after 30 years, the film holds up remarkably well, despite the obvious tropes of action films of the 1990s. (Sam and Salt defying orders and hijacking a military helicopter, then using it to face-off mid-air against a military aircraft deployed to bomb the town out of existence, is just one credibility-straining example.) The talented cast alone makes it worth a rewatch. And for Smith, it was nice to see a strong female epidemiologist as a leading character in Russo’s Bobby Keough. On the whole, “I honestly think Outbreak was fairly good,” she said.
