Nintendo Switch 2: The Ars Technica review


Nintendo’s overdue upgrade is a strong contender, even amid competition from handheld PCs.

When Nintendo launched the Switch in 2017, the sheer novelty of the new hardware brought the company a lot of renewed attention. After the market disaster of the Wii U’s homebound “second screen” tablet, Nintendo exploited advances in system-on-a-chip miniaturization to create something of a minimum viable HD-capable system that could work as both a lightweight handheld and a slightly underpowered TV-based console. That unique combination, and Nintendo’s usual selection of first-party system sellers, set the console apart from what the rest of the gaming market was offering at the time.

Eight years later, the Switch 2 launched into a transformed gaming hardware market that the original Switch played a large role in shaping, one full of portable gaming consoles that can optionally be connected to a TV. That includes full-featured handheld gaming PCs like the Steam Deck and its many imitators, but also streaming-focused Android-based gaming handhelds and retro-focused emulation machines on the cheaper end. Even Microsoft is preparing to get in on the act, streamlining the Windows gaming experience for an Asus-powered handheld gaming PC that hides the Windows desktop.

Those market changes make the Switch 2 a lot less of a novelty than its predecessor. As its name implies, it is essentially a direct sequel to the original Switch hardware, with improvements to the physical hardware and internal architecture. Rather than shaking things up with a new concept, Nintendo seems to be saying, “Hey, you liked the Switch? Here’s the same thing, but moreso.”

That “moreso” will surely be enough for players who complained about the Switch’s increasingly obvious struggles to play graphically demanding games in the last few years. But in a gaming world full of capable and usable handheld PCs, a “more of the same” Switch 2 might be a bit of a tougher sell.

Joyful Joy-Cons

Let’s start with one feature that the Switch line still can boast over most of its handheld gaming competition: the removable Joy-Cons. The new magnetic slotting system for these updated controllers on the Switch 2 is a sheer joy to use, allowing for easy and quick one-handed removal as well as a surprisingly secure portable mode connection. After a week spent snapping them on and off dozens of times, I still can’t get over how great the design feels.

The new Joy-Cons also ameliorate what was probably the largest complaint about the ones on the Switch: their size. Everything from the overall footprint to the buttons and joystick has been expanded to feel much more appropriate in larger hands. The days of average adults having to awkwardly scrunch their fingers around a Switch Joy-Con in each hand can be relegated to the past, where they belong.

Holding a single Joy-Con in two hands is still not ideal, but it works in a pinch.

Holding a single Joy-Con in two hands is still not ideal, but it works in a pinch.

Like the Switch before it, the removable Joy-Cons can also be used separately, essentially offering baseline purchasers two controllers for the price of one. The added size helps make holding an individual Joy-Con horizontally in two hands much more comfortable, especially when it comes to tapping the expanded shoulder buttons on the controllers’ inner edge. But the face buttons and joystick are still a bit too cramped and oddly placed to make this a preferred way to play for long stretches.

Still, for situations where you happen to have other players around—especially young children who might not mind the smaller-than-standard size—it’s nice to have a feasible multiplayer option without needing to invest in new controllers. And the Switch 2’s seamless compatibility with your old Switch controllers (in tabletop or docked mode, at least) provides even more control flexibility and value for upgraders.

Control compromises

The main problem with the Switch 2 Joy-Cons continues to be their thinness, which is practically unchanged from the original Switch. That’s handy for keeping the overall system profile nice and trim in portable mode, but it means the Joy-Cons are missing the bulbous, rounded palm grips you see on handhelds like the Steam Deck and standard console controllers dating back to the original PlayStation.

Without this kind of grip, the thin, rounded bottom corner of the Joy-Cons ends up wedged oddly between the fleshy parts of your palm. Your free fingers, meanwhile, are either awkwardly wrapped around the edge of the loose Joy-Cons or uncomfortably perched to support the flat back of a portable system that’s a noticeable 34 percent heavier than the original Switch. And while an included Joy-Con holster helps add these rounded grips for tabletop or docked play, the “flat finger” problem is unavoidable when playing the system in portable mode.

The included grip gives your palms a comfortable place to rest when holding the Joy-Cons.

The included grip gives your palms a comfortable place to rest when holding the Joy-Cons.

After spending a week with the Joy-Cons, I started to notice a few other compromises. Despite the added size, the face buttons are still slightly smaller than you’ll find on other controllers, meaning they can dig into the pad of your thumb when held down for extended periods. The shoulder buttons, which have also been expanded from the original Switch, still lack the increased travel and sensitivity of the analog triggers that are standard on nearly every competing controller. And the positioning of the right joystick encroaches quite close to the buttons just above it, making it easy to accidentally nudge the stick when pressing the lower B button.

Those kinds of control compromises help keep the portable Switch 2 notably smaller and lighter than most of its handheld PC competition. But they also mean my Switch 2 will probably need something like the Nyxi Hyperion Pro, which I’ve come to rely on to make portable play on the original Switch much more comfortable.

Improvements inside and out

Unlike the controllers, the screen on the Switch 2 is remarkably low on compromises. The full 1080p, 7.9-inch display supports HDR and variable refresh rates up to 120 Hz, making it a huge jump over both the original Switch and most of the screens you’ll find on competing handheld gaming PCs (or even some standard HDTVs when it comes to the maximum frame rate). While the screen lacks the truly deep blacks of a true OLED display, I found that the overall brightness (which reportedly peaks at about 450 nits) makes it hard to notice.

The custom Nvidia processor inside the Switch 2 is also a welcome improvement over a Tegra processor that was already underpowered for the Switch in 2017. We’ve covered in detail how much of a difference this makes for Switch titles that have been specially upgraded to take advantage of that extra power, fixing fuzzy graphics and frame rate issues that were common on Nintendo’s previous system. It’s hard to imagine going back after seeing Tears of the Kingdom running in a silky-smooth 60 fps or enjoying the much sharper textures and resolution of portable No Man’s Sky on the Switch 2.

However, the real proof of the Switch 2’s improved power can be seen in early third-party ports like Cyberpunk 2077, Split Fiction, Hitman World of Assassination, and Street Fighter VI, which would have required significant visual downgrades to even run on the original Switch. To my eye, the visual impact of these ports is roughly comparable to what you’d get on a PS4 Pro (in handheld mode) or an Xbox Series S (in docked mode). In the medium term, that should be more than enough performance for all but the most determined pixel-counters, given the distinctly diminishing graphical returns we’re seeing from more advanced (and more expensive) hardware like the PS5 Pro.

The biggest compromise for all this extra power comes in the battery life department. Games like Mario Kart World or Cyberpunk 2077 can take the system from a full charge to completely drained in somewhere between 2 and 2.5 hours. This time span increases significantly for less demanding games like old-school 2D classics and can be slightly extended if you reduce the screen brightness. Still, it’s a bit grating to need to rely on an external battery pack just to play Mario Kart World for an entire cross-country flight.

Externally, the Switch 2 is full of tiny but welcome improvements, like an extra upper edge USB-C port for more convenient charging and a thin-but-sturdy U-shaped stand for tabletop play. Internally, the extremely welcome high-speed storage helps cut initial load times on games like Mario Kart 8 roughly in half (16.5 seconds on the Switch versus 8.5 seconds on the Switch 2 in our testing).

But the 256GB of internal storage included in the Switch 2 is also laughably small, considering that individual digital games routinely require downloads of 50GB to 70GB. That’s especially true in a world where many third-party games are only available as Game Key Cards, which still require that the full game be downloaded. Most Switch 2 customers should budget $50 or more for a MicroSD Express card to add at least 256GB of additional storage.

Those Nintendo gimmicks

Despite the “more of the same” overall package, there are a few small areas where the Switch 2 does something truly new. Mouse mode is the most noticeable of these, letting you transform a Joy-Con into a PC-style mouse simply by placing it on its edges against most flat-ish surfaces. We tested this mode on surfaces ranging from a hard coffee table to a soft pillow-top mattress and this reviewer’s hairy thighs and found the mouse mode was surprisingly functional in every test. While the accuracy and precision fall off on the squishier and rounder of those tested surfaces, it’s something of a marvel that it works at all.

Unfortunately, the ergonomics of mouse mode still leave much to be desired. This again comes down to the thinness of the Joy-Cons, which don’t have the large, rounded palm rest you’d expect from a good PC mouse. That means getting a good sense of control in mouse mode requires hooking your thumb, ring finger, and pinky finger into a weird modified claw-like grip around the Joy-Con, a pose that becomes uncomfortable after even moderate use. A holster that lets the Joy-Con slot into a more traditional mouse shape could help with this problem; failing that, mouse mode seems destined to remain a little-used gimmick.

GameChat is the Switch 2’s other major “new” feature, letting you communicate with friends directly through the system’s built-in microphone (which works rather well even across a large and noisy living room) or an optional webcam (many standard USB cameras we tested worked just fine). It’s a welcome and simple way to connect with other players without having to resort to Discord or the bizarre external smartphone app Nintendo relied on for voice chat on the original Switch.

In most ways, it feels like GameChat is just playing catch-up to the kind of social sharing features competitors like Microsoft were already including in their consoles back in 2005. However, we appreciate GameChat’s ability to easily share a live view of your screen with friends, even if the low-frame-rate video won’t give Twitch streams a run for their money.

Those kinds of complaints can also apply to GameShare, which lets Switch 2 owners stream video of their game with a second player, allowing them to join in the game from a secondary Switch or Switch 2 console (either locally or remotely). The usability of this feature seems heavily dependent on the wireless environment in the players’ house, ranging from smooth but grainy to unplayably laggy. And the fact that GameShare only works with specially coded games is a bit annoying when Steam Remote Play offers a much more generalized remote co-op solution on PC.

The best of both worlds?

This is usually the point in a console review where I warn you that buying a console at or near launch is a poor value proposition, as you’ll never pay more for a system with fewer games. That’s not necessarily true these days. The original Switch never saw an official price drop in its eight years on the market, and price increases are becoming increasingly common for some video game hardware. If you think you’re likely to ever be in the market for a Switch 2, now might be the best time to pull the trigger.

That said, there’s not all that much to do with a brand new Switch 2 unit at the moment. Mario Kart World is being positioned as the major system seller at launch, revitalizing an ultra-popular, somewhat stale series with a mixed bag of bold new ideas. Nintendo’s other first-party launch title, the $10 Switch 2 Welcome Tour, is a tedious affair that offers a few diverting minigames amid dull slideshows and quizzes full of corny PR speak.

The rest of the Switch 2’s launch library is dominated by ports of games that have been available on major non-Switch platforms for anywhere from months to years. That’s nice if the Switch has been your only game console during that time or if you’ve been looking for an excuse to play these titles in full HD on a beautiful portable screen. For many gamers, though, these warmed-over re-releases won’t be that compelling.

Other than that, there are currently only the barest handful of completely original launch titles that require the Switch 2, none of which really provide a meaningful reason to upgrade right away. For now, once you tire of Mario Kart, you’ll be stuck replaying your old Switch games (often with welcome frame rate and resolution improvements) or checking out a trio of emulated GameCube games available to Switch Online Expansion Pack subscribers (they look and play just fine).

Looking to the future, the promise of further Nintendo first-party games is, as usual, the primary draw for the company’s hardware. In the near term, games like Donkey Kong Bananza, Pokémon Legends Z-A, and Metroid Prime 4 (which will also be available on the older Switch with less wow-inducing performance) are the biggest highlights in the pipeline. Projecting a little further out, the Switch 2 will be the only way to legitimately play Mario and Zelda adventures that seem highly likely to be can’t-miss classics, given past performance.

Nintendo aside, the Switch 2 seems well-positioned to receive able portable-ready ports of some of the more demanding third-party games in the foreseeable future. Already, we’ve seen Switch 2 announcements for catalog titles like Elden Ring and future releases like 007 First Light, as well as a handful of third-party exclusives like FromSoft’s vampire-filled Duskbloods.

Those are pretty good prospects for a $450 portable/TV console hybrid. But even with a bevy of ports and exclusives, it could be hard for the Switch 2’s library to compete with the tens of thousands of games available on any handheld PC worth its salt. You’ll pay a bit more for one of those portables if you’re looking for something that matches the quality of the Switch 2’s screen and processor—for the moment, at least. But the PC ecosystem’s wider software selection and ease of customization might make that investment worth it for gamers who don’t care too much about Nintendo’s first-party efforts.

If you found yourself either regularly using or regularly coveting a Switch at any point over the last eight years, the Switch 2 is an obvious and almost necessary upgrade. If you’ve resisted the siren song for this long, though, you can probably continue to ignore Nintendo’s once-novel hardware line.

Another one for the graveyard: Google to kill Instant Apps in December

But that was then, and this is now. Today, an increasing number of mobile apps are functionally identical to the mobile websites they are intended to replace, and developer uptake of Instant Apps was minimal. Even in 2017, loading an app instead of a website had limited utility. As a result, most of us probably only encountered Instant Apps a handful of times in all the years it was an option for developers.

To use the feature, which was delivered to virtually all Android devices by Google Play Services, developers had to create a special “instant” version of their app that was under 15MB. The additional legwork to get an app in front of a subset of new users meant this was always going to be a steep climb, and Google struggles to incentivize developers to adopt new features. Plus, there’s no way to cram in generative AI! So it’s not a shock to see Google retiring the feature.

This feature is currently listed in the collection of Google services in your phone settings as “Google Play Instant.” Unfortunately, there aren’t many examples still available if you’re curious about what Instant Apps were like—the Finnish publisher Ilta-Sanomat is one of the few still offering it. Make sure the settings toggle for Instant Apps is on if you want a little dose of nostalgia.

Rocket Report: New delay for Europe’s reusable rocket; SpaceX moves in at SLC-37


Canada is the only G7 nation without a launch program. Quebec wants to do something about that.

Welcome to Edition 7.48 of the Rocket Report! The shock of last week’s public spat between President Donald Trump and SpaceX founder Elon Musk has worn off, and Musk expressed regret for some of his comments going after Trump on social media. Musk also backtracked from his threat to begin decommissioning the Dragon spacecraft, currently the only way for the US government to send people to the International Space Station. Nevertheless, there are many people who think Musk’s attachment to Trump could end up putting the US space program at risk, and I’m not convinced that danger has passed.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Quebec invests in small launch company. The government of Quebec will invest CA$10 million ($7.3 million) into a Montreal-area company that is developing a system to launch small satellites into space, The Canadian Press reports. Quebec Premier François Legault announced the investment into Reaction Dynamics at the company’s facility in Longueuil, a Montreal suburb. The province’s economy minister, Christine Fréchette, said the investment will allow the company to begin launching microsatellites into orbit from Canada as early as 2027.

Joining its peers … Canada is the only G7 nation without a domestic satellite launch capability, whether it’s through an independent national or commercial program or through membership in the European Space Agency, which funds its own rockets. The Canadian Space Agency has long eschewed any significant spending on developing a Canadian satellite launcher, and a handful of commercial launch startups in Canada haven’t gotten very far. Reaction Dynamics was founded in 2017 by Bachar Elzein, formerly a researcher in multiphase and reactive flows at École Polytechnique de Montréal, where he specialized in propulsion and combustion dynamics. Reaction Dynamic plans to launch its first suborbital rocket later this year, before attempting an orbital flight with its Aurora rocket as soon as 2027. (submitted by Joey S-IVB)

Another year, another delay for Themis. The European Space Agency’s Themis program has suffered another setback, with the inaugural flight of its reusable booster demonstrator now all but certain to slip to 2026, European Spaceflight reports. It has been nearly six years since the European Space Agency kicked off the Themis program to develop and mature key technologies for future reusable rocket stages. Themis is analogous to SpaceX’s Grasshopper reusable rocket prototype tested more than a decade ago, with progressively higher hop tests to demonstrate vertical takeoff and vertical landing techniques. When the program started, an initial hop test of the first Themis demonstrator was expected to take place in 2022.

Tethered to terra firma … ArianeGroup, which manufactures Europe’s Ariane rockets, is leading the Themis program under contract to ESA, which recently committed an additional 230 million euros ($266 million) to the effort. This money is slated to go toward the development of a single-engine variant of the Themis program, continued development of the rocket’s methane-fueled engine, and upgrades to a test stand at ArianeGroup’s propulsion facility in Vernon, France. Two months ago, an official update on the Themis program suggested the first Themis launch campaign would begin before the end of the year. Citing sources close to the program, European Spaceflight reports the first Themis integration tests at the Esrange Space Center in Sweden are now almost certain to slip from late 2025 to 2026.

French startup tests a novel rocket engine. While Europe’s large government-backed rocket initiatives face delays, the continent’s space industry startups are moving forward on their own. One of these companies, a French startup named Alpha Impulsion, recently completed a short test-firing of an autophage rocket engine, European Spaceflight reports. These aren’t your normal rocket engines that burn conventional kerosene, methane, or hydrogen fuel. An autophage engine literally consumes itself as it burns, using heat from the combustion process to melt its plastic fuselage and feed the molten plastic into the combustion chamber in a controlled manner. Alpha Impulsion called the May 27 ground firing a successful test of the “largest autophage rocket engine in the world.”

So, why hasn’t this been done before? … The concept of a self-consuming rocket engine sounds like an idea that’s so crazy it just might work. But the idea remained conceptual from when it was first patented in 1938 until an autophage engine was fired in a controlled manner for the first time in 2018. The autophage design offers several advantages, including its relative simplicity compared to the complex plumbing of liquid and hybrid rockets. But there are serious challenges associated with autophage engines, including how to feed molten fuel into the combustion chamber and how to scale it up to be large enough to fly on a viable rocket.

Rocket trouble delays launch of private crew mission. A propellant leak in a Falcon 9 booster delayed the launch of a fourth Axiom Space private astronaut mission to the International Space Station this week, Space News reports. SpaceX announced the delay Tuesday, saying it needed more time to fix a liquid oxygen leak found in the Falcon 9 booster during inspections following a static-fire test Sunday. “Once complete–and pending Range availability–we will share a new launch date,” the company stated. The Ax-4 mission will ferry four commercial astronauts, led by retired NASA commander Peggy Whitson, aboard a Dragon spacecraft to the ISS for an approximately 14-day stay. Whitson will be joined by crewmates from India, Poland, and Hungary.

Another problem, too … While SpaceX engineers worked on resolving the propellant leak on the ground, a leak of another kind in orbit forced officials to order a longer delay to the Ax-4 mission. In a statement Thursday, NASA said it is working with the Russian space agency to understand a “new pressure signature” in the space station’s Russian service module. For several years, ground teams have monitored a slow air leak in the aft part of the service module, and NASA officials have identified it as a safety risk. NASA’s statement on the matter was vague, only saying that cosmonauts on the station recently inspected the module’s interior surfaces and sealed additional “areas of interest.” The segment is now holding pressure, according to NASA.

SpaceX tries something new with Falcon 9. With nearly 500 launches under its belt, SpaceX’s Falcon 9 rocket isn’t often up to new tricks. But the company tried something new following a launch on June 7 with a radio broadcasting satellite for SiriusXM. The Falcon 9’s upper stage placed the SXM-10 satellite into an elongated, high-altitude transfer orbit, as is typical for payloads destined to operate in geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. When a rocket releases a satellite in this type of high-energy orbit, the upper stage has usually burned almost all of its propellant, leaving little fuel to steer itself back into Earth’s atmosphere for a destructive reentry. This means these upper stages often remain in space for decades, becoming a piece of space junk that transits across the orbits of many other satellites.

Now, a solution … SpaceX usually deorbits rockets after they deploy payloads like Starlink satellites into low-Earth orbit, but deorbiting a rocket from a much higher geosynchronous transfer orbit is a different matter. “Last week, SpaceX successfully completed a controlled deorbit of the SiriusXM-10 upper stage after GTO payload deployment,” wrote Jon Edwards, SpaceX’s vice president of Falcon and Dragon programs. “While we routinely do controlled deorbits for LEO stages (e.g., Starlink), deorbiting from GTO is extremely difficult due to the high energy needed to alter the orbit, making this a rare and remarkable first for us. This was only made possible due to the hard work and brilliance of the Falcon GNC (guidance, navigation, and control) team and exemplifies SpaceX’s commitment to leading in both space exploration and public safety.”

New Glenn gets a tentative launch date. Five months have passed since Blue Origin’s New Glenn rocket made its mostly successful debut in January. At one point, the company targeted “late spring” for the second launch of the rocket. However, on Monday, Blue Origin’s CEO, Dave Limp, acknowledged on social media that the rocket’s next flight will now no longer take place until at least August 15, Ars reports. Although he did not say so, this may well be the only other New Glenn launch this year. The mission, with an undesignated payload, will be named “Never Tell Me the Odds,” due to the attempt to land the booster. “One of our key mission objectives will be to land and recover the booster,” Limp wrote. “This will take a little bit of luck and a lot of excellent execution. We’re on track to produce eight GS2s [second stages] this year, and the one we’ll fly on this second mission was hot-fired in April.”

Falling shortBefore 2025 began, Limp set expectations alongside Blue Origin founder Jeff Bezos: New Glenn would launch eight times this year. That’s not going to happen. It’s common for launch companies to take a while ramping up the flight rate for a new rocket, but Bezos told Ars in January that his priority for Blue Origin this year was to hit a higher cadence with New Glenn. Elon Musk’s rift with President Donald Trump could open a pathway for Blue Origin to capture more government business if the New Glenn rocket is able to establish a reliable track record. Meanwhile, Limp told Blue Origin employees last month that Jarrett Jones, the manager running the New Glenn program, is taking a sabbatical. Although it appears Jones’ leave may have been planned, the timing is curious.

Making way for Starship at Cape Canaveral. The US Air Force is moving closer to authorizing SpaceX to move into one of the largest launch pads at Cape Canaveral Space Force Station in Florida, with plans to use the facility for up to 76 launches of the company’s Starship rocket each year, Ars reports. A draft Environmental Impact Statement (EIS) released by the Department of the Air Force, which includes the Space Force, found SpaceX’s planned use of Space Launch Complex 37 (SLC-37) at Cape Canaveral would have no significant negative impacts on local environmental, historical, social, and cultural interests. The Air Force also found SpaceX’s plans at SLC-37 will have no significant impact on the company’s competitors in the launch industry.

Bringing the rumble … SLC-37 was the previous home to United Launch Alliance’s Delta IV rocket, which last flew from the site in April 2024, a couple of months after the military announced SpaceX was interested in using the launch pad. While it doesn’t have a lease for full use of the launch site, SpaceX has secured a “right of limited entry” from the Space Force to begin preparatory work. This included the explosive demolition of the launch pad’s Delta IV-era service towers and lightning masts Thursday, clearing the way for eventual construction of two Starship launch towers inside the perimeter of SLC-37. The new Starship launch towers at SLC-37 will join other properties in SpaceX’s Starship empire, including nearby Launch Complex 39A at NASA’s Kennedy Space Center, and SpaceX’s privately owned facility at Starbase, Texas.

Preps continue for Starship Flight 10. Meanwhile, at Starbase, SpaceX is moving forward with preparations for the next Starship test flight, which could happen as soon as next month following three consecutive flights that fell short of expectations. This next launch will be the 10th full-scale test flight of Starship. Last Friday, June 6, SpaceX test-fired the massive Super Heavy booster designated to launch on Flight 10. All 33 of its Raptor engines ignited on the launch pad in South Texas. This is a new Super Heavy booster. On Flight 9 last month, SpaceX flew a reused Super Heavy booster that launched and was recovered on a flight in January.

FAA signs off on SpaceX investigation … The Federal Aviation Administration said Thursday it has closed the investigation into Starship Flight 8 in March, which spun out of control minutes after liftoff, showering debris along a corridor of ocean near the Bahamas and the Turks and Caicos Islands. “The FAA oversaw and accepted the findings of the SpaceX-led investigation,” an agency spokesperson said. “The final mishap report cites the probable root cause for the loss of the Starship vehicle as a hardware failure in one of the Raptor engines that resulted in inadvertent propellant mixing and ignition. SpaceX identified eight corrective actions to prevent a reoccurrence of the event.” SpaceX implemented the corrective actions prior to Flight 9 last month, when Starship progressed further into its mission before starting to tumble in space. It eventually reentered the atmosphere over the Indian Ocean. The FAA has mandated a fresh investigation into Flight 9, and that inquiry remains open.

A warlord brings chaos in Foundation S3 trailer

Foundation returns for a third season next month on Apple TV+.

Foundation, Apple TV+’s lavish adaptation (or re-mix, if you prefer) of Isaac Asimov’s seminal sci-fi series, returns for its third season next month, and the streaming platform has dropped an official trailer to give us a taste of what’s in store.

As previously reported, the first season ended with a major time jump of 138 years, and S2 focused on the Second Crisis: imminent war between Empire and the Foundation, along with an enemy seeking to destroy Empire from within. The Foundation, meanwhile, adopted the propaganda tactics of religion to recruit new acolytes to the cause. We also met a colony of “Mentalics” with psionic abilities. We’re getting another mega time jump for the Third Crisis.

Per the official premise:

Set 152 years after the events of S2, The Foundation has become increasingly established far beyond its humble beginnings while the Cleonic Dynasty’s Empire has dwindled. As both of these galactic powers forge an uneasy alliance, a threat to the entire galaxy appears in the fearsome form of a warlord known as “The Mule” whose sights are set on ruling the universe by use of physical and military force, as well as mind control. It’s anyone’s guess who will win, who will lose, who will live, and who will die as Hari Seldon, Gaal Dornick, the Cleons and Demerzel play a potentially deadly game of intergalactic chess.

All-wheel drive EVs at 210 mph? Formula E’s next car gets massive upgrade.

The governing body for world motorsport met in Macau yesterday. Among the jobs for the Fédération Internationale de l’Automobile was to sign off on various calendars for next season, which is why there’s now a clash between the F1 Monaco Grand Prix and the 24 Hours of Le Mans and also between the Indy 500 and F1’s annual visit to Canada. The Formula E calendar was also announced, although with a pair of blank TBCs in the middle, I’ll hold off calling it finalized.

The US round will now take place in late January, and it’s moving venues yet again. No longer will you need to drive an hour south of Miami; instead, the northern outskirts of the city will suffice. The infield at Homestead is no more, and the sport has negotiated a race at the Hard Rock Stadium, albeit on a different layout than the one used by F1. It seems that Formula E’s recent “Evo Sessions” race between influencers, which was held at the stadium, proved convincing.

The really interesting Formula E news from Macau won’t take effect until the 2026–2027 season, and that’s the arrival of the Gen4 car.

The current machine is no slouch, not since they took some constraints off the Gen3 car this season. The addition of part-time all-wheel drive has improved what was already a very racey series, but for now, it’s only available for the final part of qualifying, the start of the race, and when using the mandatory Attack Mode that has added some interesting new strategy to the sport.

New tires, more aero, and way more power

From the start of the 2026–2027 season, all-wheel drive will finally be permanent for the single-seater EVs. It is long past time, given that virtually every high-performance EV on the road powers both its axles, and it marks the first time the FIA has approved a permanent AWD single-seater since the technology was outlawed from F1 decades ago.

Dwarkesh Patel on Continual Learning

A key question going forward is the extent to which making further AI progress will depend upon some form of continual learning. Dwarkesh Patel offers us an extended essay considering these questions and reasons to be skeptical of the pace of progress for a while. I am less skeptical about many of these particular considerations, and do my best to explain why in detail.

Separately, Ivanka Trump recently endorsed a paper with a discussion I liked a lot less but that needs to be discussed given how influential her voice might (mind you I said might) be to policy going forward, so I will then cover that here as well.

Dwarkesh Patel explains why he doesn’t think AGI is right around the corner, and why AI progress today is insufficient to replace most white collar employment: That continual learning is both necessary and unsolved, and will be a huge bottleneck.

He opens with this quote:

Rudiger Dornbusch: Things take longer to happen than you think they will, and then they happen faster than you thought they could.

Clearly this means one is poorly calibrated, but also yes, and I expect it to feel like this as well. Either capabilities, diffusion or both will be on an exponential, and the future will be highly unevenly distributed until suddenly parts of it aren’t anymore. That seems to be true fractally as well, when the tech is ready and I figure out how to make AI do something, that’s it, it’s done.

Here is Dwarkesh’s Twitter thread summary:

Dwarkesh Patel: Sometimes people say that even if all AI progress totally stopped, the systems of today would still be economically transformative. I disagree. The reason that the Fortune 500 aren’t using LLMs to transform their workflows isn’t because the management is too stodgy.

Rather, it’s genuinely hard to get normal humanlike labor out of LLMs. And this has to do with some fundamental capabilities these models lack.

New blog post where I explain why I disagree with this, and why I have slightly longer timelines to AGI than many of my guests.

I think continual learning is a huge bottleneck to the usefulness of these models, and extended computer use may take years to sort out.

Link here.

There is no consensus definition of transformational but I think this is simply wrong, in the sense that LLMs being stuck without continual learning at essentially current levels would not stop them from having a transformational impact. There are a lot of other ways to get a ton more utility out of what we already have, and over time we would build around what the models can do rather than giving up the moment they don’t sufficiently neatly fit into existing human-shaped holes.

When we do solve human like continual learning, however, we might see a broadly deployed intelligence explosion *even if there’s no more algorithmic progress*.

Simply from the AI amalgamating the on-the-job experience of all the copies broadly deployed through the economy.

I’d bet 2028 for computer use agents that can do taxes end-to-end for my small business as well as a competent general manager could in a week: including chasing down all the receipts on different websites, emailing back and forth for invoices, and filing to the IRS.

That being said, you can’t play around with these models when they’re in their element and still think we’re not on track for AGI.

Strongly agree with that last statement. Regardless of how much we can do without strictly solving continual learning, continual learning is not solved… yet.

These are simple, self contained, short horizon, language in-language out tasks – the kinds of assignments that should be dead center in the LLMs’ repertoire. And they’re 5/10 at them. Don’t get me wrong, that’s impressive.

But the fundamental problem is that LLMs don’t get better over time the way a human would. The lack of continual learning is a huge huge problem. The LLM baseline at many tasks might be higher than an average human’s. But there’s no way to give a model high level feedback.

You’re stuck with the abilities you get out of the box. You can keep messing around with the system prompt. In practice this just doesn’t produce anything even close to the kind of learning and improvement that human employees experience.

The reason humans are so useful is not mainly their raw intelligence. It’s their ability to build up context, interrogate their own failures, and pick up small improvements and efficiencies as they practice a task.

You make an AI tool. It’s 5/10 out of the box. What level of Skill Issue are we dealing with here, that stops it from getting better over time assuming you don’t get to upgrade the underlying model?

You can obviously engage in industrial amounts of RL or other fine-tuning, but that too only goes so far.

You can use things like memory, or train LoRas, or various other incremental tricks. That doesn’t enable radical changes, but I do think it can work for the kinds of preference learning Dwarkesh is complaining he currently doesn’t have access to, and you can if desired go back and fine tune the entire system periodically.

How do you teach a kid to play a saxophone? You have her try to blow into one, listen to how it sounds, and adjust. Now imagine teaching saxophone this way instead: A student takes one attempt. The moment they make a mistake, you send them away and write detailed instructions about what went wrong. The next student reads your notes and tries to play Charlie Parker cold. When they fail, you refine the instructions for the next student.

This just wouldn’t work. No matter how well honed your prompt is, no kid is just going to learn how to play saxophone from just reading your instructions. But this is the only modality we as users have to ‘teach’ LLMs anything.

Are you even so sure about that? If the context you can give is hundreds of thousands to millions of tokens at once, with ability to conditionally access millions or billions more? If you can create new tools and programs and branch workflows, or have it do so on your behalf, and call instances with different contexts and procedures for substeps? If you get to keep rewinding time and sending in the exact same student in the same mental state as many times as you want? And so on, including any number of things I haven’t mentioned or thought about?

I am confident that with enough iterations and work (and access to the required physical tools) I could write a computer program to operate a robot to play the saxophone essentially perfectly. No, you can’t do this purely via the LLM component, but that is why we are moving towards MCP and tool use for such tasks.

I get that Dwarkesh has put a lot of work into getting his tools to 5/10. But it’s nothing compared to the amount of work that could be done, including the tools that could be involved. That’s not a knock on him, that wouldn’t be a good use of his time yet.

LLMs actually do get kinda smart and useful in the middle of a session. For example, sometimes I’ll co-write an essay with an LLM. I’ll give it an outline, and I’ll ask it to draft the essay passage by passage. All its suggestions up till 4 paragraphs in will be bad. So I’ll just rewrite the whole paragraph from scratch and tell it, “Hey, your shit sucked. This is what I wrote instead.” At that point, it can actually start giving good suggestions for the next paragraph. But this whole subtle understanding of my preferences and style is lost by the end of the session.

Okay, so that seems like it is totally, totally a Skill Issue now? As in, Dwarkesh Patel has a style. A few paragraphs of that style clue the LLM into knowing how to help. So… can’t we provide it with a bunch of curated examples of similar exercises, and put them into context in various ways (Claude projects just got 10x more context!) and start with that?

Even Claude Code will often reverse a hard-earned optimization that we engineered together before I hit /compact – because the explanation for why it was made didn’t make it into the summary.

Yeah, this is super annoying, I’ve run into it, but I can think of some obvious fixes for this, especially if you notice what you want to preserve? One obvious way is to do what humans do, which is to put it into comments in the code saying what the optimization is and why to keep it, which then remain in context whenever Claude considers ripping them out, I don’t know if that works yet but it totally should.

I’m not saying I have the magical solution to all this but it all feels like it’s One Weird Trick (okay, maybe 10 working together) away from working in ways I could totally figure out if I had a team behind me and I focused on it.

My guess is this will not look like ‘learn like a human’ exactly. Different tools are available, so we’ll first get the ability to solve this via doing something different. But also, yeah, I think with enough skill and the right technique (on the level of the innovation that created reasoning models) you could basically do what humans do? Which involves effectively having the systems automatically engage in various levels of meta and updating, often quite heavily off a single data point.

It is hard to overstate how much time and effort goes into training a human employee.

There are many jobs where an employee is not net profitable for years. Hiring decisions are often made on the basis of what will be needed in year four or beyond.

That ignores the schooling that you also have to do. A doctor in America requires starting with a college degree, then four years of medical school, then four years of residency, and we have to subsidize that residency because it is actively unprofitable. That’s obviously an extreme case, but there are many training programs or essentially apprenticeships that last for years, including highly expensive time from senior people and expensive real world mistakes.

Imagine what it took to make Dwarkesh Patel into Dwarkesh Patel. Or the investment he makes in his own employees.

Even afterwards, in many ways you will always be ‘stuck with’ various aspects of those employees, and have to make the most of what they offer. This is standard.

Claude Opus estimates, and I think this is reasonable, that for every two hours humans spend working, they spend one hour learning, with a little less than half of that learning essentially ‘on the job.’

If you need to train a not a ‘universal’ LLM but a highly specific-purpose LLM, and have a massive compute budget with which to do so, and you mostly don’t care about how it performs out of distribution the same way you mostly don’t for an employee (as in, you teach it what you teach a human, which is ‘if this is outside your distribution or you’re failing at it then run it up the chain to your supervisor,’ and you have a classifier for that) and you can build and use tools along the way? Different ballgame.

It makes sense, given the pace of progress, for most people and companies not to put that kind of investment into AI ‘employees’ or other AI tasks. But if things do start to stall out, or they don’t, either way the value proposition on that will quickly improve. It will start to be worth doing. And we will rapidly learn new ways of doing it better, and have the results available to be copied.

Here’s his predictions on computer use in particular, to see how much we actually disagree:

When I interviewed Anthropic researchers Sholto Douglas and Trenton Bricken on my podcast, they said that they expect reliable computer use agents by the end of next year. We already have computer use agents right now, but they’re pretty bad. They’re imagining something quite different.

Their forecast is that by the end of next year, you should be able to tell an AI, “Go do my taxes.” And it goes through your email, Amazon orders, and Slack messages, emails back and forth with everyone you need invoices from, compiles all your receipts, decides which are business expenses, asks for your approval on the edge cases, and then submits Form 1040 to the IRS.

I’m skeptical. I’m not an AI researcher, so far be it for me to contradict them on technical details. But given what little I know, here’s why I’d bet against this forecast:

  • As horizon lengths increase, rollouts have to become longer. The AI needs to do two hours worth of agentic computer use tasks before we can even see if it did it right. Not to mention that computer use requires processing images and video, which is already more compute intensive, even if you don’t factor in the longer rollout. This seems like this should slow down progress.

Let’s take the concrete example here, ‘go do my taxes.’

This is a highly agentic task, but like a real accountant you can choose to ‘check its work’ if you want, or get another AI to check the work, because you can totally break this down into smaller tasks that allow for verification, or present a plan of tasks that can be verified. Similarly, if you are training TaxBot to do people’s taxes for them, you can train TaxBot on a lot of those individual subtasks, and give it clear feedback.

Almost all computer use tasks are like this? Humans also mostly don’t do things that can’t be verified for hours?

And the core building block issues of computer use seem mostly like very short time horizon tasks with very easy verification methods. If you can get lots of 9s on the button clicking and menu navigation and so on, I think you’re a lot of the way there.

The subtasks are also 99%+ things that come up relatively often, and that don’t present any non-trivial difficulties. A human accountant already will have to occasionally say ‘wait, I need you the taxpayer to tell me what the hell is up with this thing’ and we’re giving the AI in 2028 the ability to do this too.

I don’t see any fundamental difference between the difficulties being pointed out here, and the difficulties of tasks we have already solved.

  • We don’t have a large pretraining corpus of multimodal computer use data. I like this quote from Mechanize’s post on automating software engineering: “For the past decade of scaling, we’ve been spoiled by the enormous amount of internet data that was freely available for us to use. This was enough for cracking natural language processing, but not for getting models to become reliable, competent agents. Imagine trying to train GPT-4 on all the text data available in 1980—the data would be nowhere near enough, even if we had the necessary compute.”

    Again, I’m not at the labs. Maybe text only training already gives you a great prior on how different UIs work, and what the relationship between different components is. Maybe RL fine tuning is so sample efficient that you don’t need that much data. But I haven’t seen any public evidence which makes me think that these models have suddenly gotten less data hungry, especially in this domain where they’re substantially less practiced.

    Alternatively, maybe these models are such good front end coders that they can just generate millions of toy UIs for themselves to practice on. For my reaction to this, see bullet point below.

I’m not going to keep working for the big labs for free on this one by giving even more details on how I’d solve all this, but this totally seems like highly solvable problems, and also this seems like a case of the person saying it can’t be done interrupting the people doing it? It seems like progress is being made rapidly.

  • Even algorithmic innovations which seem quite simple in retrospect seem to take a long time to iron out. The RL procedure which DeepSeek explained in their R1 paper seems simple at a high level. And yet it took 2 years from the launch of GPT-4 to the release of o1.

  • Now of course I know it is hilariously arrogant to say that R1/o1 were easy – a ton of engineering, debugging, pruning of alternative ideas was required to arrive at this solution. But that’s precisely my point! Seeing how long it took to implement the idea, ‘Train the model to solve verifiable math and coding problems’, makes me think that we’re underestimating the difficulty of solving the much gnarlier problem of computer use, where you’re operating in a totally different modality with much less data.

I think two years is how long we had to have the idea of o1 and commit to it, then to implement it. Four months is roughly the actual time it took from ‘here is that sentence and we know it works’ to full implementation. Also we’re going to have massively more resources to pour into these questions this time around, and frankly I don’t think any of these insights are even as hard to find as o1, especially now that we have reasoning models to use as part of this process.

I think there are other potential roadblocks along the way, and once you factor all of those in you can’t be that much more optimistic, but I see this particular issue as not that likely to pose that much of a bottleneck for long.

His predictions are he’d take 50/50 bets on: 2028 for an AI that can ‘just go do your taxes as well as a human accountant could’ and 2032 for ‘can learn details and preferences on the job as well as a human can.’ I’d be inclined to take other side of both of those bets, assuming it means by EOY, for the 2032 one we’d need to flesh out details.

But if we have the ‘AI that does your taxes’ in 2028 then 2029 and 2030 look pretty weird, because this implies other things:

Daniel Kokotajlo: Great post! This is basically how I think about things as well. So why the difference in our timelines then?

–Well, actually, they aren’t that different. My median for the intelligence explosion is 2028 now (one year longer than it was when writing AI 2027), which means early 2028 or so for the superhuman coder milestone described in AI 2027, which I’d think roughly corresponds to the “can do taxes end-to-end” milestone you describe as happening by end of 2028 with 50% probability. Maybe that’s a little too rough; maybe it’s more like month-long horizons instead of week-long. But at the growth rates in horizon lengths that we are seeing and that I’m expecting, that’s less than a year…

–So basically it seems like our only serious disagreement is the continual/online learning thing, which you say 50% by 2032 on whereas I’m at 50% by end of 2028. Here, my argument is simple: I think that once you get to the superhuman coder milestone, the pace of algorithmic progress will accelerate, and then you’ll reach full AI R&D automation and it’ll accelerate further, etc. Basically I think that progress will be much faster than normal around that time, and so innovations like flexible online learning that feel intuitively like they might come in 2032 will instead come later that same year.

(For reference AI 2027 depicts a gradual transition from today to fully online learning, where the intermediate stages look something like “Every week, and then eventually every day, they stack on another fine-tuning run on additional data, including an increasingly high amount of on-the-job real world data.” A janky unprincipled solution in early 2027 that gives way to more elegant and effective things midway through the year.)

I found this an interestingly wrong thing to think:

Richard: Given the risk of fines and jail for filling your taxes wrong, and the cost of processing poor quality paperwork that the government will have to bear, it seems very unlikely that people will want AI to do taxes, and very unlikely that a government will allow AI to do taxes.

The rate of fully accurately filing your taxes is, for anyone whose taxes are complex, basically 0%. Everyone makes mistakes. When the AI gets this right almost every time, it’s already much better than a human accountant, and you’ll have a strong case that what happened was accidental, which means at worst you pay some modest penalties.

Personal story, I was paying accountants at a prestigious firm that will go unnamed to do my taxes, and they literally just forgot to include paying city tax at all. As in, I’m looking at the forms, and I ask, ‘wait why does it have $0 under city tax?’ and the guy essentially says ‘oh, whoops.’ So, yeah. Mistakes are made. This will be like self-driving cars, where we’ll impose vastly higher standards of accuracy and law abidance on the AIs, and they will meet them because the bar really is not that high.

There were also some good detailed reactions and counterarguments from others:

Near: finally some spicy takes around here.

Rohit: The question is whether we need humanlike labour for transformative economic outcomes, or whether we can find ways to use the labour it does provide with a different enough workflow that it adds substantial economic advantage.

Sriram Krishnan: Really good post from @dwarkesh_sp on continuous learning in LLMs.

Vitalik Buterin: I have high probability mass on longer timelines, but this particular issue feels like the sort of limitation that’s true until one day someone discovers a magic trick (think eg. RL on CoT) that suddenly makes it no longer true.

Sriram Krishnan: Agree – CoT is a particularly good example.

Ryan Greenblatt: I agree with much of this post. I also have roughly 2032 medians to things going crazy, I agree learning on the job is very useful, and I’m also skeptical we’d see massive white collar automation without further AI progress.

However, I think Dwarkesh is wrong to suggest that RL fine-tuning can’t be qualitatively similar to how humans learn.

In the post, he discusses AIs constructing verifiable RL environments for themselves based on human feedback and then argues this wouldn’t be flexible and powerful enough to work, but RL could be used more similarly to how humans learn.

My best guess is that the way humans learn on the job is mostly by noticing when something went well (or poorly) and then sample efficiently updating (with their brain doing something analogous to an RL update). In some cases, this is based on external feedback (e.g. from a coworker) and in some cases it’s based on self-verification: the person just looking at the outcome of their actions and then determining if it went well or poorly.

So, you could imagine RL’ing an AI based on both external feedback and self-verification like this. And, this would be a “deliberate, adaptive process” like human learning. Why would this currently work worse than human learning?

Current AIs are worse than humans at two things which makes RL (quantitatively) much worse for them:

1. Robust self-verification: the ability to correctly determine when you’ve done something well/poorly in a way which is robust to you optimizing against it.

2. Sample efficiency: how much you learn from each update (potentially leveraging stuff like determining what caused things to go well/poorly which humans certainly take advantage of). This is especially important if you have sparse external feedback.

But, these are more like quantitative than qualitative issues IMO. AIs (and RL methods) are improving at both of these.

All that said, I think it’s very plausible that the route to better continual learning routes more through building on in-context learning (perhaps through something like neuralese, though this would greatly increase misalignment risks…).

Some more quibbles:

– For the exact podcasting tasks Dwarkesh mentions, it really seems like simple fine-tuning mixed with a bit of RL would solve his problem. So, an automated training loop run by the AI could probably work here. This just isn’t deployed as an easy-to-use feature.

– For many (IMO most) useful tasks, AIs are limited by something other than “learning on the job”. At autonomous software engineering, they fail to match humans with 3 hours of time and they are typically limited by being bad agents or by being generally dumb/confused. To be clear, it seems totally plausible that for podcasting tasks Dwarkesh mentions, learning is the limiting factor.

– Correspondingly, I’d guess the reason that we don’t see people trying more complex RL based continual learning in normal deployments is that there is lower hanging fruit elsewhere and typically something else is the main blocker. I agree that if you had human level sample efficiency in learning this would immediately yield strong results (e.g., you’d have very superhuman AIs with 10^26 FLOP presumably), I’m just making a claim about more incremental progress.

– I think Dwarkesh uses the term “intelligence” somewhat atypically when he says “The reason humans are so useful is not mainly their raw intelligence. It’s their ability to build up context, interrogate their own failures, and pick up small improvements and efficiencies as they practice a task.” I think people often consider how fast someone learns on the job as one aspect of intelligence. I agree there is a difference between short feedback loop intelligence (e.g. IQ tests) and long feedback loop intelligence and they are quite correlated in humans (while AIs tend to be relatively worse at long feedback loop intelligence).

More thoughts/quibbles:

– Dwarkesh notes “An AI that is capable of online learning might functionally become a superintelligence quite rapidly, even if there’s no algorithmic progress after that point.” This seems reasonable, but it’s worth noting that if sample efficient learning is very compute expensive, then this might not happen so rapidly.

– I think AIs will likely overcome poor sample efficiency to achieve a very high level of performance using a bunch of tricks (e.g. constructing a bunch of RL environments, using a ton of compute to learn when feedback is scarce, learning from much more data than humans due to “learn once deploy many” style strategies). I think we’ll probably see fully automated AI R&D prior to matching top human sample efficiency at learning on the job. Notably, if you do match top human sample efficiency at learning (while still using a similar amount of compute to the human brain), then we already have enough compute for this to basically immediately result in vastly superhuman AIs (human lifetime compute is maybe 3e23 FLOP and we’ll soon be doing 1e27 FLOP training runs). So, either sample efficiency must be worse or at least it must not be possible to match human sample efficiency without spending more compute per data-point/trajectory/episode.

Matt Reardon: Dwarkesh commits the sin of thinking work you’re personally close to is harder-than-average to automate.

Herbie Bradley: I mean this is just correct? most researchers I know think continual learning is a big problem to be solved before AGI

Matt Reardon: My main gripe is that “<50%" [of jobs being something you can automate soon] should be more like "<15%"

Danielle Fong: Gell-Mann Amnesia for AI.

Reardon definitely confused me here, but either way I’d say that Dwarkesh Patel is a 99th percentile performer. He does things most other people can’t do. That’s probably going to be harder to automate than most other white collar work? The bulk of hours in white collar work are very much not bespoke things and don’t act to put state or memory into people in subtle ways?

Now that we’ve had a good detailed discussion and seen several perspectives, it’s time to address another discussion of related issues, because it is drawing attention from an unlikely source.

After previously amplifying Situational Awareness, Ivanka Trump is back in the Essay Meta with high praise for The Era of Experience, authored by David Silver and (oh no) Richard Sutton.

Situational Awareness was an excellent pick. I do not believe this essay was a good pick. I found it a very frustrating, unoriginal and unpersuasive paper to read. To the extent it is saying something new I don’t agree, but it’s not clear to what extent it is saying anything new. Unless you want to know about this paper exactly because Ivanka is harping it, you should skip this section.

I think the paper effectively mainly says we’re going to do a lot more RL and we should stop trying to make the AIs mimic, resemble or be comprehensible to humans or trying to control their optimization targets?

Ivanka Trump: Perhaps the most important thing you can read about AI this year : “Welcome to the Era of Experience”

This excellent paper from two senior DeepMind researchers argues that AI is entering a new phase—the “Era of Experience”—which follows the prior phases of simulation-based learning and human data-driven AI (like LLMs).

The authors’ posit that future AI breakthroughs will stem from learning through direct interaction with the world, not from imitating human-generated data.

This is not a theory or distant future prediction. It’s a description of a paradigm shift already in motion.

Let me know what you think !

Glad you asked, Ivanka! Here’s what I think.

The essay starts off with a perspective we have heard before, usually without much of an argument behind it: That LLMs and other AIs trained only on ‘human data’ is ‘rapidly approaching a limit,’ we are running out of high-quality data, and thus to progress significantly farther AIs will need to move into ‘the era of experience,’ meaning learning continuously from their environments.

I agree that the standard ‘just feed it more data’ approach will run out of data with which to scale, but there are a variety of techniques already being used to get around this. We have lots of options.

The leading example the paper itself gives of this in the wild is AlphaProof, which ‘interacted with a formal proofing system’ which seems to me like a clear case of synthetic data working and verification being easier than generation, rather than ‘experience.’ If the argument is simply that RL systems will learn by having their outputs evaluated, that isn’t news.

They claim to have in mind something rather different from that, and with this One Weird Trick they assert Superintelligence Real Soon Now:

Our contention is that incredible new capabilities will arise once the full potential of experiential learning is harnessed. This era of experience will likely be characterised by agents and environments that, in addition to learning from vast quantities of experiential data, will break through the limitations of human-centric AI systems in several further dimensions:

• Agents will inhabit streams of experience, rather than short snippets of interaction.

• Their actions and observations will be richly grounded in the environment, rather than interacting via human dialogue alone.

• Their rewards will be grounded in their experience of the environment, rather than coming from human prejudgement.

• They will plan and/or reason about experience, rather than reasoning solely in human terms.

We believe that today’s technology, with appropriately chosen algorithms, already provides a sufficiently powerful foundation to achieve these breakthroughs. Furthermore, the pursuit of this agenda by the AI community will spur new innovations in these directions that rapidly progress AI towards truly superhuman agents.

I suppose if the high level takeaway is ‘superintelligence is likely coming reasonably soon with the right algorithms’ then there’s no real disagreement?

They then however discuss tool calls and computer use, which then seems like a retreat back into an ordinary RL paradigm? It’s also not clear to me what the authors mean by ‘human terms’ versus ‘plan and/or reason about experience,’ or even what ‘experience’ means here. They seem to be drawing a distinction without a difference.

If the distinction is simply (as the paper implies in places) that the agents will do self-evaluation rather than relying on human feedback, I have some important news about how existing systems already function? They use the human feedback and other methods to train an AI feedback system that does most of the work? And yes they often include ‘real world’ feedback systems in that? What are we even saying here?

They also seem to be drawing a distinction between the broke ‘human feedback’ and the bespoke ‘humans report physical world impacts’ (or ‘other systems measure real world impacts’) as if the first does not often encompass the second. I keep noticing I am confused what the authors are trying to say.

For reasoning, they say it is unlikely human methods of reasoning and human language are optimal, more efficient methods of thought must exist. I mean, sure, but that’s also true for humans, and it’s obvious that you can use ‘human style methods of thought’ to get to superintelligence by simply imagining a human plus particular AI advantages.

As many have pointed out (and is central to AI 2027) encouraging AIs to use alien-looking inhuman reasoning styles we cannot parse is likely a very bad idea even if it would be more effective, what visibility we have will be lost and also it likely leads to alien values and breaks many happy things. Then again, Richard Sutton is one of the authors of this paper and he thinks we should welcome succession, as in the extinction of humanity, so he wouldn’t care.

They try to argue against this by saying that while agents pose safety risks and this approach may increase those safety risks, the approach may also have safety benefits. First, they say this allows the AI to adapt to its environment, as if the other agent could not do this or this should make us feel safer.

Second, they say ‘the reward function may itself be adapted through experience,’ in terms of risk that’s worse you know that that’s worse, right? They literally say ‘rather than blindly optimizing a signal such as the number of paperclips it can adopt to indications of human concern,’ this shows a profound lack of understanding and curiosity of where the whole misspecification of rewards problem is coming from or the arguments about it from Yudkowsky (since they bring in the ‘paperclips’).

Adapting autonomously and automatically towards something like ‘level of human concern’ is exactly the kind of metric and strategy that is absolutely going to encourage perverse outcomes and get you killed at the limit. You don’t get out of the specification problem by saying you can specify something messier and let the system adapt around it autonomously, that only makes it worse, and in no way addresses the actual issue.

The final argument for safety is that relying on physical experience creates time limitations, which provides a ‘natural break,’ which is saying that capabilities limits imposed by physical interactions will keep things more safe? Seriously?

There is almost nothing in the way of actual evidence or argument in the paper that is not fully standard, beyond a few intuition pumps. There are many deep misunderstandings, including fully backwards arguments, along the way. We may well want to rely a lot more on RL and on various different forms of ‘experiential’ data and continuous learning, but given how much worse it was than I expected this post updated me in the opposite direction of that which was clearly intended.

Protesters summon, burn Waymo robotaxis in Los Angeles after ICE raids

The robotaxi company Waymo has suspended service in some parts of Los Angeles after some of its vehicles were summoned and then vandalized by protesters angry with ongoing raids by US Immigration and Customs Enforcement. Five of Waymo’s autonomous Jaguar I-Pace electric vehicles were summoned downtown to the site of anti-ICE protests, at which point they were vandalized with slashed tires and spray-painted messages. Three were set on fire.

The Los Angeles Police Department warned people to avoid the area due to risks from toxic gases given off by burning EVs. And Waymo told Ars that it is “in touch with law enforcement” regarding the matter.

The protesters in Los Angeles were outraged after ICE, using brutal tactics, began detaining people in raids across the city. Thousands of Angelenos took to the streets over the weekend to confront the masked federal enforcers and, in some cases, forced them away.

In response, the Trump administration mobilized more than 300 National Guard soldiers without consulting with or being requested to do so by the California governor.

California Governor Gavin Newsom has promised to sue the administration. “Donald Trump has created the conditions you see on your TV tonight. He’s exacerbated the conditions. He’s, you know, lit the proverbial match. He’s putting fuel on this fire, ever since he announced he was taking over the National Guard—an illegal act, an immoral act, an unconstitutional act,” Newsom said in an interview.

Waymo began offering rides in Los Angeles last November, and by January, the company said it had driven almost 2 million miles in the city. But there is some animosity toward robotaxis and food delivery robots, which are now being used by the Los Angeles Police Department as sources of surveillance footage. In April, the LAPD published footage obtained from a Waymo that it used to investigate a hit-and-run.

A long-shot plan to mine the Moon comes a little closer to reality

The road ahead

Meyerson said the company’s current plan is to fly a prospecting mission in 2027, a payload of less than 100 kg, likely on a commercial lander that is part of NASA’s Commercial Lunar Payload Services program. Two years later, the company seeks to fly a pilot plant. Meyerson said the size of this plant will depend on the launch capability available (i.e., if Starship is flying to the Moon, they’ll go big, and smaller if not).

Following this, Interlune is targeting 2032 for the launch of a solar-powered operating plant, which would include five mobile harvesters. The operation would also be able to return material mined to Earth. The total mass for this equipment would be about 40 metric tons, which could fly on a single Starship or two New Glenn Mk 2 landers. This would, understandably, be highly ambitious and capital-intensive. After raising $15 million last year, Meyerson said Interlune is planning a second fundraising round that should begin soon.

There are some outside factors that may be beneficial for Interlune. One is that China has a clear and demonstrated interest in sending humans to the Moon and has already sent rovers to explore for helium-3 resources. Moreover, with the exit of Jared Isaacman as a nominee to lead NASA, the Trump administration is likely to put someone in the position who is more focused on lunar activities. One candidate, a retired Air Force General named Steve Kwast, is a huge proponent of mining helium-3.

Interlune has a compelling story, as there are almost no other lunar businesses focused solely on commercial activities that will drive value from mining the lunar surface. In that sense, they could be a linchpin of a lunar economy. However, they have a long way to go, and a lot of lunar regolith to plow through, before they start delivering for customers.

apple’s-ai-driven-stem-splitter-audio-separation-tech-has-hugely-improved-in-a-year

Apple’s AI-driven Stem Splitter audio separation tech has hugely improved in a year

Consider an example from a song I’ve been working on. Here’s a snippet of the full piece:


After running Logic’s original Stem Splitter on the snippet, I was given four tracks: Vocals, Drums, Bass, and “Other.” They all isolated their parts reasonably well, but check out the static and artifacting when you isolate the bass track:



The vocal track came out better, but it was still far from ideal:


Now, just over a year later, Apple has released a point update for Logic that delivers “enhanced audio fidelity” for Stem Splitter—along with support for new stems for guitar and piano.

Logic now splits audio into more stems.

The difference in quality is significant, as you can hear in the new bass track:


And the new vocal track, though still lacking the pristine fidelity of the original recording, is nevertheless greatly improved:


The ability to separate out guitars and pianos is also welcome, and it works well. Here’s the piano part:



Pretty impressive leap in fidelity for a point release!

There are plenty of other stem-splitting tools, of course, and many have had a head start on Apple. With its new release, however, Apple has certainly closed the gap.

Izotope’s RX 11, for instance, is a highly regarded (and expensive!) piece of software that can do wonders when it comes to repairing audio and reducing clicks, background noise, and sibilance.

RX11 screenshot

RX11, ready to split some stems.

It includes a stem-splitting feature that can produce four outputs (vocal, bass, drums, and other), and it produces usable audio—but I’m not sure I’d rank its output more highly than Logic’s. Compare for yourself on the vocal and bass stems:



In any event, the AI/machine learning revolution has certainly arrived in the music world, and the rapid quality increase in stem-splitting tools in just a few years shows just what these AI systems are capable of when trained on enough data. I remain especially impressed by how the best stem splitters can extract not just a clean vocal but also the reverb/delay tail. Having access to the original recordings will always be better—but stem-splitting tech is improving quickly.

Estate of woman who died in 2021 heat dome sues Big Oil for wrongful death


At least 100 heat-related deaths in Washington state came during the unprecedented heat wave.

The daughter of a woman who was killed by extreme heat during the 2021 Pacific Northwest heat dome has filed a first-of-its-kind lawsuit against major oil companies claiming they should be held responsible for her death.

The civil lawsuit, filed on May 29 in King County Superior Court in Seattle, is the first wrongful death case brought against Big Oil in the US in the context of climate change. It attempts to hold some of the world’s biggest fossil fuel companies liable for the death of Juliana Leon, who perished from overheating during the heat dome event, which scientists have determined would have been virtually impossible absent human-caused climate change.

“The extreme heat that killed Julie was directly linked to fossil fuel-driven alteration of the climate,” the lawsuit asserts. It argues that fossil fuel defendants concealed and misrepresented the climate change risks of their products and worked to delay a transition to cleaner energy alternatives. Furthermore, oil companies knew decades ago that their conduct would have dangerous and deadly consequences, the case alleges.

“Defendants have known for all of Julie’s life that their affirmative misrepresentations and omissions would claim lives,” the complaint claims. Leon’s daughter, Misti, filed the suit on behalf of her mother’s estate.

At 65, Juliana Leon was driving home from a medical appointment in Seattle on June 28, 2021, a day when the temperature peaked at 108° Fahrenheit (42.2° Celsius). She had the windows rolled down since the air conditioner in her car wasn’t working, but with the oven-like outdoor temperatures she quickly succumbed to the stifling heat. A passerby found her unresponsive in her car, which was pulled over on a residential street. Emergency responders were unable to revive her. The official cause of death was determined to be hyperthermia, or overheating.

There were at least 100 heat-related deaths in the state from June 26 to July 2, 2021, according to the Washington State Department of Health. That unprecedented stretch of scorching high temperatures was the deadliest weather-related event in Washington’s history. Climate change linked to the burning of fossil fuels intensified this extreme heat event, scientists say.

Misti Leon’s complaint argues that big oil companies “are responsible” for her mother’s climate change-related death. “Through their failure to warn, marketing, distribution, extraction, refinement, transport, and sale of fossil fuels, defendants each bear responsibility for the spike in atmospheric CO2 levels that have resulted in climate change, and thus the occurrence of a virtually impossible weather event and the extreme temperatures of the Heat Dome,” the suit alleges.

Defendants include ExxonMobil, BP, Chevron, Shell, ConocoPhillips, and Phillips 66. Phillips 66 declined to comment; the rest of the companies did not respond to requests for comment.

The plaintiff is represented by the Bechtold Law Firm, based in Missoula, Montana. The lawsuit brings state tort law claims of wrongful death, failure to warn, and public nuisance, and seeks relief in the form of damages as well as a public education campaign to “rectify defendants’ decades of misinformation.”

Major oil and gas companies are currently facing more than two dozen climate damages and deception cases brought by municipal, state, and tribal governments, including a case filed in 2023 by Multnomah County, Oregon, centered around the 2021 Pacific Northwest heat dome. The Leon case, however, is the first climate liability lawsuit filed by an individual against the fossil fuel industry.

“This is the first case that is directly making the connection between the misconduct and lies of big oil companies and a specific, personalized tragedy, the death of Julie Leon,” said Aaron Regunberg, accountability director for Public Citizen’s climate program.

“It puts a human face on it,” Pat Parenteau, emeritus professor of law at Vermont Law and Graduate School, told Inside Climate News.

Climate accountability advocates say the lawsuit could open up a new front for individuals suffering from climate change-related harms to pursue justice against corporate polluters who allegedly lied about the risks of their products.

“Big Oil companies have known for decades that their products would cause catastrophic climate disasters that would become more deadly and destructive if they didn’t change their business model. But instead of warning the public and taking steps to save lives, Big Oil lied and deliberately accelerated the problem,” Richard Wiles, president of the Center for Climate Integrity, said in a statement. “This latest case—the first filed on behalf of an individual climate victim—is another step toward accountability.”

“It’s a model for victims of climate disasters all across the country,” said Regunberg. “Anywhere there’s an extreme weather event with strong attribution science connecting it to climate change, families experiencing a tragedy can file a very similar case.”

Regunberg and several other legal experts have argued that Big Oil could face criminal prosecution for crimes such as homicide and reckless endangerment in the context of climate change, particularly given evidence of internal industry documents suggesting companies like Exxon knew that unabated fossil fuel use could result in “catastrophic” consequences and deaths. A 1996 presentation from an Exxon scientist, for example, outlines projected human health impacts stemming from climate change, including “suffering and death due to thermal extremes.”

The Leon case could “help lay the groundwork” for potential climate homicide cases, Regunberg said. “Wrongful death suits are important. They provide a private remedy to victims of wrongful conduct that causes a death. But we also think there’s a need for public justice, and that’s the role that criminal prosecution is supposed to have,” he told Inside Climate News.

The lawsuit is likely to face a long uphill battle in the courts. Other climate liability cases against these companies brought by government entities have been tied up in procedural skirmishes, some for years, and no case has yet made it to trial.

“In this case we have a grieving woman going up against some of the most powerful corporations in the world, and we’ve seen all the legal firepower they are bringing to bear on these cases,” Regunberg said.

But if the case does eventually make it to trial, it could be a game-changer. “That’s going to be a jury in King County, Washington, of people who probably experienced and remember the Pacific heat dome event, and maybe they know folks who were impacted. I think that’s going to be a compelling case that has a good chance of getting an outcome that provides some justice to this family,” Regunberg said.

Even if it doesn’t get that far, the lawsuit still “marks a significant development in climate liability,” according to Donald Braman, an associate professor of criminal law at Georgetown University and co-author of a paper explaining the case for prosecuting Big Oil for climate homicide.

“As climate attribution science advances, linking specific extreme weather events to anthropogenic climate change with greater confidence, the legal arguments for liability are strengthening. This lawsuit, being the first of its kind for wrongful death in this context, will be closely watched and could set important precedents, regardless of its ultimate outcome,” he said. “It reflects a growing societal demand for accountability for climate-related harms.”

Ted Cruz bill: States that regulate AI will be cut out of $42B broadband fund

BEAD changes: No fiber preference, no low-cost mandate

The BEAD program is separately undergoing an overhaul because Republicans don’t like how it was administered by Democrats. The Biden administration spent about three years developing rules and procedures for BEAD and then evaluating plans submitted by each US state and territory, but the Trump administration has delayed grants while it rewrites the rules.

While Biden’s Commerce Department decided to prioritize the building of fiber networks, Republicans have pushed for a “tech-neutral approach” that would benefit cable companies, fixed wireless providers, and Elon Musk’s Starlink satellite service.

Secretary of Commerce Howard Lutnick previewed changes in March, and today he announced more details of the overhaul that will eliminate the fiber preference and various requirements imposed on states. One notable but unsurprising change is that the Trump administration won’t let states require grant recipients to offer low-cost Internet plans at specific rates to people with low incomes.

The National Telecommunications and Information Administration (NTIA) “will refuse to accept any low-cost service option proposed in a [state or territory’s] Final Proposal that attempts to impose a specific rate level (i.e., dollar amount),” the Trump administration said. Instead, ISPs receiving subsidies will be able to continue offering “their existing, market driven low-cost plans to meet the statutory low-cost requirement.”

The Benton Institute for Broadband & Society criticized the overhaul, saying that the Trump administration is investing in the cheapest broadband infrastructure instead of the best. “Fiber-based broadband networks will last longer, provide better, more reliable service, and scale to meet communities’ ever-growing connectivity needs,” the advocacy group said. “NTIA’s new guidance is shortsighted and will undermine economic development in rural America for decades to come.”

The Trump administration’s overhaul drew praise from cable lobby group NCTA-The Internet & Television Association, whose members will find it easier to obtain subsidies. “We welcome changes to the BEAD program that will make the program more efficient and eliminate onerous requirements, which add unnecessary costs that impede broadband deployment efforts,” NCTA said. “These updates are welcome improvements that will make it easier for providers to build faster, especially in hard-to-reach communities, without being bogged down by red tape.”

Millions of low-cost Android devices turn home networks into crime platforms

Millions of low-cost devices for media streaming, in-vehicle entertainment, and video projection are infected with malware that turns consumer networks into platforms for distributing malware, concealing nefarious communications, and performing other illicit activities, the FBI has warned.

The malware infecting these devices, known as BadBox, is based on Triada, a malware strain discovered in 2016 by Kaspersky Lab, which called it “one of the most advanced mobile Trojans” the security firm’s analysts had ever encountered. It employed an impressive kit of tools, including rooting exploits that bypassed security protections built into Android and functions for modifying the Android OS’s all-powerful Zygote process. Google eventually updated Android to block the methods Triada used to infect devices.

The threat remains

A year later, Triada returned, only this time, devices came pre-infected before they reached consumers’ hands. In 2019, Google confirmed that the supply-chain attack affected thousands of devices and that the company had once again taken measures to thwart it.

In 2023, security firm Human Security reported on BigBox, a Triada-derived backdoor it found preinstalled on thousands of devices manufactured in China. The malware, which Human Security estimated was installed on 74,000 devices around the world, facilitated a range of illicit activities, including advertising fraud, residential proxy services, the creation of fake Gmail and WhatsApp accounts, and infecting other Internet-connected devices.
