AI leaders want to hit the brakes after years of reckless speed

AI leaders want to hit the brakes after years of reckless speed

fivenewscrypto    septembre 15, 2026   

For years now, the major frontier AI labs have all been acting as if they're in an all-out, winner-take-all race with control of world-changing machine superintelligence (or at least market-changing artificial general intelligence) at the finish line. This weekend, the industry as a whole rapidly started turning away from that posture, urging coordination on slowing down the development of frontier AI that they say could soon be too dangerous and unknowable to control.

Anthropic's Dario Amodei was at the forefront of this change in tone, arguing in a nearly 4,000-word essay this weekend that "we must slow the pace at which we improve the capabilities of AI models" to avoid "a race to the bottom, spurred by commercial incentives, [that] can make [catastrophic] risks more acute."

Within hours, other AI leaders were echoing the same call. OpenAI co-founder and CEO Sam Altman posted his agreement on social media and said similar pacing discussions had been taking place at OpenAI. Alphabet Chief Scientist and Google DeepMind cofounder and chair Demis Hassabis said that Amodei's essay "points towards the right path forward," and renewed his own recent call for an industry-wide standards body. Microsoft CEO Satya Nadella posted that the company "welcome[s] the research, focus, and deliberate pacing needed to get alignment right as the design goal," ahead of the release of a lengthy "humanist AI" code of conduct for its models.

Online hate researcher keeps hammering X despite deportation threat

Online hate researcher keeps hammering X despite deportation threat

fivenewscrypto    septembre 15, 2026   

The US is not backing down from its fight to deport noncitizen technology researchers who monitor safety risks on the biggest online platforms.

In July, a judge blocked as unconstitutional an immigration policy that the US relied on to weigh whether to detain and deport people who flag illegal or harmful online content as national security risks. In his announcement of the policy, Secretary of State Marco Rubio explained that by targeting a list of researchers—which he stood “ready and willing” to expand—the policy supposedly served to prevent foreign nationals from manipulating digital town squares and censoring Americans.

However, in his order siding with the Coalition for Independent Technology Research (CITR) and staying the policy, US District Judge James Boasberg said the US showed no evidence linking any targeted researchers to a foreign power that might be attempting to censor Americans or manipulate US public debate. Deemed too broad, the policy could sweep in seemingly any noncitizen working in content moderation, the judge said.

Prehistoric builders transported Devil's Arrows 11 miles

Prehistoric builders transported Devil's Arrows 11 miles

Stonehenge is the most famous example of megalithic architecture across Britain and Ireland, but there are plenty of others, including Calanais, Newgrange, and Avebury, as well as the Devil's Arrows. The latter is Britain's tallest standing stone alignment, yet little is known about the provenance of its stones. Scientists have confirmed that the stones came from a site 18 kilometers (11 miles) away, transported by humans rather than glacial movement, according to a paper published in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences.

"Sites in southern England and Scotland receive considerable attention but monuments like the Devil's Arrows have remained comparatively understudied despite their significance," said co-author Jim Leary of the University of York. "We have now proved that Neolithic communities moved several 25-ton stones across Yorkshire, transforming a familiar site into an epic quest to create a sacred landscape."

Stonehenge has been the focus of recent chemical analyses identifying where all the stones that make up the structure came from, revealing that many originated in quarries a significant distance away. For instance, a 2019 study concluded that the 42 bluestones that make up the inner ring came all the way from western Wales. The outer layer of sarsen stones hails from much closer to home: Marlborough Downs, an area of round, grassy hills 25 to 30 km (17 miles) north of Stonehenge, which has the largest concentration of sarsen in the UK.

Steam Frame: The Ars Technica review

Steam Frame: The Ars Technica review

fivenewscrypto    septembre 15, 2026   

In the 2010s, Valve was at the forefront of a virtual reality revolution that looked to some like it would upend the gaming industry. The Valve of six to ten years ago seemed committed to being a major player in the world of PC-connected VR headsets, first through its “strategic partnership” with HTC on the impressive-for-the-time Vive headset (plus the SteamVR platform standard that powered it) and then years later with its own Index headset (and proof-of-concept adventure Half-Life: Alyx).

Then came the Meta (previously Oculus) Quest, a low-powered, low-cost headset that proved the vast majority of VR-curious gamers didn’t want to bother with being literally tethered to a bulky, expensive gaming PC. As the Quest line carved out a modest niche through the 2020s, Valve seemed more or less satisfied to let its earlier VR hardware and software ambitions wither on the vine.

Those years of Valve’s benign neglect of VR make the imminent release of the $1,059 Steam Frame—which starts taking reservations today—more than a little surprising. Now that virtual reality’s hype-fueled, revolutionary promises have decidedly not played out, Valve is somehow ready and willing to limp headfirst into the world of standalone VR headsets—today, in 2026. And after spending a week or so with Valve’s latest foray into gaming hardware, the Frame somehow feels simultaneously overengineered and underbaked, depending on how you look at it.

"Offensively cheap": Solar power is looking up

"Offensively cheap": Solar power is looking up

fivenewscrypto    septembre 15, 2026   

In the badlands of Chakwal, in north-central Pakistan, Bestway Cement is transforming plots of dry earth and olive and peach groves into a forest of solar panels.

Its efforts will add 6.34 megawatts of generation capacity by the end of the year, the company says, in addition to the 26 MW of photovoltaic cells currently in place. Already, solar generates over a quarter of the electricity powering its cement plant.

“It’s the only way we can compete,” says Abdul Waheed, the general manager at Chakwal, which produces over 3 million tonnes of cement per year. “Our rivals have already gone in this direction.”

New corners, new lights for 2028 Volvo XC40

New corners, new lights for 2028 Volvo XC40

Volvo provided flights from Washington, DC, to London, England, and accommodation so Ars could see its refreshed vehicles. Ars does not accept paid editorial content.

Most cars get a midlife facelift about four years after first hitting the streets. It’s a chance for automakers to update the styling and introduce new features and engineering changes that are usually minor but can be quite dramatic—the Polestar 2 swapping from front- to rear-wheel drive comes readily to mind. I can’t think of too many cars that have gone on to have a second update, but here’s one: the 2028 Volvo XC40.

First debuting in 2017, Volvo gave the XC40 a tweak for model year 2023. Rather than launch an all-new version, it has decided to give the popular crossover another update for MY28 with the aim of keeping things fresh. “By enhancing the XC40’s design, technology, and safety features, we've created the best version of the XC40 yet,” said Akhil Krishnan, interim lead for the 30 and 40 Series at Volvo Cars. “This already-popular model is now set to continue being one of our best-selling cars for years to come.”

The most obvious changes are the new front and rear lights. Up front we still see the distinctive “Thor’s Hammer” daylight running light signature, but the new matrix LED light clusters appear more minimalist, hiding their details from view. The rear similarly gets new LEDs. But Volvo’s designers have been at work elsewhere, shaving away the corners of the car to make what was already a small SUV take up slightly less room.

F1 in Madrid: Like Monaco but twice as long and none of the glamour

F1 in Madrid: Like Monaco but twice as long and none of the glamour

fivenewscrypto    septembre 14, 2026   

It’s been quite a couple of weeks for Formula 1. First, its annual visit to one of the oldest tracks on the calendar, the Italian temple of speed that is Monza, just outside Milan. Apologies for no Ars report, but your correspondent was on the ground, on vacation, learning the hard way that attempts to call the circuit “accessible by public transport” can still involve walking several miles. The place was packed with Tifosi—the hardcore Italian superfans—dressed in red, who had their hopes dashed almost immediately as Charles Leclerc first ruined his teammate’s race, then his own, all within the first two laps.

Salvation came in the form of the first Italian title contender in my lifetime, Mercedes’ Kimi Antonelli. Opting to take a new engine and other power unit components meant Antonelli would start the race from 19th. But the kid is in fine form right now, and Monza’s long straights and slow corners make for several good overtaking spots. I declared to my race companions that morning that “he’s going to podium, easily,” but if anything, I was too cautious. By the time Leclerc’s heavy crash at Parabolica had stopped the race, Antonelli was already up to 12th.

From the second standing start, on fresh medium tires and still needing a second pitstop, he made short work of the rest of the grid, including his teammate George Russell, who spent much of the race in the lead, on a theoretically faster one-stop strategy. Even a mistake from Antonelli that saw him make an excursion through a gravel trap as he tried to pass Russell couldn’t stop his charge, and he became the first Italian to win the Italian Grand Prix in 60 years—fairy tale stuff, surely.
