Are Big Tech's Nuclear Construction Deals a Tipping Point for Small Modular Reactors? (aol.com) 71

Fortune reports on "a watershed moment" in American's nuclear power industry: In January, Meta partnered with Gates' TerraPower and Sam Altman-backed Oklo to develop about 4 gigawatts of combined SMR projects — enough to power almost 3 million homes — for "clean, reliable energy" both for Meta's planned Prometheus AI mega campus in Ohio and beyond. Analysts see Meta as the start of more Big Tech nuclear construction deals — not just agreements with existing plants or restarts such as the now-Microsoft-backed Three Mile Island. "That was the first shot across the bow," said Dan Ives, head of tech research for Wedbush Securities, of the Meta deals. "I would be shocked if every Big Tech company doesn't make some play on nuclear in 2026, whether a strategic partnership or acquisitions."

Ives pointed out there are more data centers under construction than there are active data centers in the U.S. "I believe clean energy around nuclear is going to be the answer," he said. "I think 2030 is the key threshold to hit some sort of scale and begin the next nuclear era in the United States." Smaller SMR reactors can be built in as little as three years instead of the decade required for traditional large reactors. And they can be expanded, one or two modular reactors at a time, to meet increasingly greater energy demand from 'hyperscalers,' the companies that build and operate data centers. "There's major risk if nuclear doesn't happen," Oklo chairman and CEO Jacob DeWitte told Fortune, citing the need for emission-free power and consistent baseload electricity to meet skyrocketing demand. "The hyperscalers, as the ultimate consumers of power are, are looking at the space and seeing that the market is real. They can play a major role in helping make that happen," DeWitte said, speaking in his fast-talking, Silicon Valley startup mode.

Musk Predicts SpaceX Will Launch More AI Compute Per Year Than the Cumulative Total on Earth (substack.com) 245

Elon Musk told podcast host Dwarkesh Patel and Stripe co-founder John Collison that space will become the most economically compelling location for AI data centers in less than 36 months, a prediction rooted not in some exotic technical breakthrough but in the basic math of electricity supply: chip output is growing exponentially, and electrical output outside China is essentially flat.

Solar panels in orbit generate roughly five times the power they do on the ground because there is no day-night cycle, no cloud cover, no atmospheric loss, and no atmosphere-related energy reduction. The system economics are even more favorable because space-based operations eliminate the need for batteries entirely, making the effective cost roughly 10 times cheaper than terrestrial solar, Musk said. The terrestrial bottleneck is already real.

Musk said powering 330,000 Nvidia GB300 chips -- once you account for networking hardware, storage, peak cooling on the hottest day of the year, and reserve margin for generator servicing -- requires roughly a gigawatt at the generation level. Gas turbines are sold out through 2030, and the limiting factor is the casting of turbine vanes and blades, a process handled by just three companies worldwide.

Five years from now, Musk predicted, SpaceX will launch and operate more AI compute annually than the cumulative total on Earth, expecting at least a few hundred gigawatts per year in space. Patel estimated that 100 gigawatts alone would require on the order of 10,000 Starship launches per year, a figure Musk affirmed. SpaceX is gearing up for 10,000 launches a year, Musk said, and possibly 20,000 to 30,000.

Western Digital Plots a Path To 140 TB Hard Drives Using Vertical Lasers and 14-Platter Designs (tomshardware.com) 62

Western Digital this week laid out a roadmap that stretches its 3.5-inch hard drive platform to 14 platters and pairs it with a new vertical-emitting laser for heat-assisted magnetic recording, a combination the company says will push individual drive capacities beyond 140 TB in the 2030s.

The vertical laser, developed over six years and already working in WD's labs, emits light straight down onto the disk rather than from the edge, delivering more thermal energy while occupying less vertical space -- enabling areal densities up to 10 TB per platter, up from today's 4 TB, and room for additional platters in the same enclosure. WD's first commercial HAMR drives arrive in late 2026 at 40-44 TB on an 11-platter design, ramping into volume production in 2027. A 12-platter platform follows in 2028 at 60 TB, and WD expects to hit 100 TB by around 2030.

Valve's Steam Machine Has Been Delayed, and the RAM Crisis Will Impact Pricing (theverge.com) 40

Valve has pushed back the launch of its Steam Machine, Steam Frame and Steam Controller hardware from its original Q1 2026 window to a vaguer "first half of the year" target, blaming the ongoing memory and storage shortage that has been squeezing the tech industry.

The company said in a post today that rising component prices and limited availability forced it to revisit both its shipping schedule and pricing plans. Valve had previously indicated the Steam Machine would be priced at the entry level of the PC space.

Russian Spy Satellites Have Intercepted EU Communications Satellites (arstechnica.com) 85

European security officials believe two Russian space vehicles have intercepted the communications of at least a dozen key satellites over the continent. From a report: Officials believe that the likely interceptions, which have not previously been reported, risk not only compromising sensitive information transmitted by the satellites but could also allow Moscow to manipulate their trajectories or even crash them.

Russian space vehicles have shadowed European satellites more intensively over the past three years, at a time of high tension between the Kremlin and the West following Moscow's full-scale invasion of Ukraine. For several years, military and civilian space authorities in the West have been tracking the activities of Luch-1 and Luch-2 -- two Russian objects that have carried out repeated suspicious maneuvers in orbit.

Both vehicles have made risky close approaches to some of Europe's most important geostationary satellites, which operate high above the Earth and service the continent, including the UK, as well as large parts of Africa and the Middle East. According to orbital data and ground-based telescopic observations, they have lingered nearby for weeks at a time, particularly over the past three years. Since its launch in 2023, Luch-2 has approached 17 European satellites.

Anthropic Pledges To Keep Claude Ad-free, Calls AI Conversations a 'Space To Think' (anthropic.com) 31

Anthropic said today that its AI assistant Claude will not carry advertising of any kind -- no sponsored links next to conversations, no advertiser influence on the model's responses, and no unsolicited third-party product placements -- calling Claude a "space to think" that should remain free of commercial interruption. The announcement comes days after Anthropic's chief rival, OpenAI, announced plans to bring ads to some of its ChatGPT offerings.

Anthropic said its internal analysis of Claude conversations found that a significant share involve sensitive or deeply personal topics. An advertising-based model would also create incentives to optimize for engagement and time spent rather than usefulness, Anthropic said, noting that the most helpful AI interaction might be a short one that doesn't prompt further conversation.

Anthropic generates revenue from enterprise contracts and paid subscriptions. The company said it is exploring agentic commerce -- Claude handling a purchase or booking on a user's behalf -- but stressed that all such interactions should be user-initiated, not advertiser-driven. Anthropic has also brought AI tools to educators in over 60 countries and said it may consider lower-cost subscription tiers and regional pricing.

Google Plots Big Expansion in India as US Restricts Visas 92

Alphabet is plotting to dramatically expand its presence in India [non-paywalled source], with the possibility of taking millions of square feet in new office space in Bangalore, India's tech hub. From a report: Google's parent company has leased one office tower and purchased options on two others in Alembic City, a development in the Whitefield tech corridor, totaling 2.4 million square feet, according to people familiar with the deal. The first tower is expected to open to employees in the coming months, while construction on the remaining two is set to conclude next year.

Options in the real estate industry give would-be tenants the exclusive right to rent, or in some cases buy, a property at a predetermined price within a specific time frame. It's also possible Alphabet will not exercise the option to use the additional towers. If it does take all of the space, the complex could accommodate as many as 20,000 additional staff, which could more than double the company's footprint in India, said the people, asking not to be identified because the plans aren't public. Alphabet currently employs around 14,000 in the country, out of a global workforce of roughly 190,000.

[...] US President Donald Trump's visa restrictions have made it harder to bring foreign talent to America, prompting some companies to recruit more staff overseas. India has become an increasingly important place for US companies to hire, particularly in the race to dominate artificial intelligence.

SpaceX Acquires xAI in $1.25 Trillion All-Stock Deal (cnbc.com) 202

Elon Musk's SpaceX has acquired his AI startup xAI in an all-stock deal that values the combined entity at $1.25 trillion, ahead of what would be the largest initial public offering in history. SpaceX pegged its own valuation at $1 trillion -- a markup from the $800 billion it commanded in a December secondary stock sale -- and priced xAI at $250 billion based on a recent $20 billion funding round that valued the two-year-old AI company at $230 billion.

SpaceX CFO Bret Johnsen told investors on a call Monday that shares in the combined company would be priced at $527 and that xAI shares would convert into SpaceX stock at a roughly seven-to-one exchange rate. The company is still targeting a June IPO expected to raise as much as $50 billion, surpassing Saudi Aramco's $29 billion listing in 2019.

Musk said the least expensive way to do AI computation within two to three years will be in space. "Global electricity demand for AI simply cannot be met with terrestrial solutions, even in the near term, without imposing hardship on communities and the environment," he wrote. SpaceX filed last Friday for permission to launch up to a million satellites into Earth's orbit. xAI merged with Musk's social media platform X last March in a $113 billion deal, and Tesla announced a $2 billion investment in xAI last week.

EU Deploys New Government Satcom Program in Sovereignty Push (spacenews.com) 32

The EU "has switched on parts of its homegrown secure satellite communications network for the first time," reports Bloomberg, calling it part of a €10.6 billion push to "wean itself off US support amid growing tensions."

SpaceNews notes the new government program GOVSATCOM pools capacity from eight already on-oribit satellites from France, Spain, Italy, Greece and Luxembourg — both national and commercial. And they cite this prediction by EU Defense and Space Commissioner Andrius Kubilius.

The program could expand by 2027. "All member states can now have access to sovereign satellite communications — military and government, secure and resilient, built in Europe, operated in Europe, and under European control," [Kubilius said during his opening remarks at the European Space Conference]... Beginning in 2029, GOVSATCOM is expected to integrate with the 290 satellites in the Infrastructure for Resilience, Interconnectivity and Security by Satellite constellation, known as IRIS2, and be fully operational... "The goal is connectivity and security for all of Europe — guaranteed access for all member states and full European control."

Bitcoin Drops 40% in Four Months. Bloomberg Blames Absence of Buyers and Belief (yahoo.com) 153

October saw Bitcoin reach $123,742. But less than four months later, "The world's largest cryptocurrency slipped below $76,000..." Bloomberg reports, "dropping about 40% from its 2025 peak..."

"What began as a sharp crash in October has morphed into something more corrosive: a selloff shaped not by panic, but by absence of buyers, momentum and belief." Unlike the October drawdown, there's been no obvious spark, cascading liquidations or systemic shock — just fading demand, thinning liquidity, and a token that's untethered to broader markets. Bitcoin has failed to respond to geopolitical stress, dollar weakness, or risk rallies. Even during gold and silver's violent swings in recent weeks, crypto saw no rotation. Bitcoin fell nearly 11% in January, marking its fourth straight monthly decline — the longest losing streak since 2018, during the crash that followed the 2017 boom in initial coin offerings...

Even more striking than the drop itself is the relative lack of optimism around it on social media. In a space known for relentless bravado and "number go up" memes, Bitcoin's slide has been met with little cheerleading or dip-buying fanfare... [Despite legislative wins and some institutional investments] Many investors say that optimism was front-run. Prices rallied early — and then stalled. Meanwhile, spot ETFs continue to bleed, a sign of weakening conviction among mainstream buyers — many of whom are now underwater after buying at higher prices.

On Thursday, Bitcoin closed at 88,228. By Sunday it had plunged another 13%, to $76,790...

Microbes In Space Mutated and Developed a Remarkable Ability (sciencealert.com) 22

"A box full of viruses and bacteria has completed its return trip to the International Space Station," reports ScienceAlert, "and the changes these 'bugs' experienced in their travels could help us Earthlings tackle drug-resistant infections..." Scientists aboard the space station incubated different combinations of bacteria and phages for 25 days, while the research team led by biochemist Vatsan Raman carried out the same experiments in Madison, down here on Earth. "Space fundamentally changes how phages and bacteria interact: infection is slowed, and both organisms evolve along a different trajectory than they do on Earth," the researchers explain. In the weightlessness of space, bacteria acquired mutations in genes involved in the microbe's stress response and nutrient management. Their surface proteins also changed. After a slow start, the phages mutated in response, so they could continue binding to their victims.

The team found that certain space-specific phage mutations were especially effective at killing Earth-bound bacteria responsible for urinary tract infections (UTIs). More than 90 percent of the bacteria responsible for UTIs are antibiotic-resistant, making phage treatments a promising alternative.

Blue Origin Announces Two-Year Pause in Space Tourism - to Focus on the Moon (techcrunch.com) 29

TechCrunch reports: Jeff Bezos' space company Blue Origin is pausing its space tourism flights for "no less than two years" in order to focus all of its resources on upcoming missions to the moon, the company announced Friday. The decision puts a temporary halt on a program that Blue Origin has been using to fly humans past the Kármán line, the recognized boundary of space, for the last five years. Blue Origin made the announcement just a few weeks ahead of the expected third launch of its New Glenn mega-rocket, which is slated for late February...

The company said Friday that New Shepard has flown 38 times and carried 98 humans to space, along with more than 200 scientific and research payloads.

"The move is a clear sign that Blue Origin is going all in on its moon program as the company races with rival SpaceX," reports the Business Standard, "to be the first private company to land humans on the lunar surface for Nasa's Artemis program." Blue Origin holds a $3.4 billion contract with Nasa to develop its Blue Moon lander, designed to shuttle astronauts to and from the moon, with a landing originally targeted for 2029... The company is targeting the launch and landing of a cargo version of its lander as soon as this year, as a test ahead of eventually landing humans. Blue Origin has also presented an accelerated plan to Nasa for developing a lander that may be ready for carrying astronauts ahead of Starship, the large new rocket from Elon Musk's SpaceX.

'Reverse Solar Panel' Generates Electricity at Night (extremetech.com) 34

Researchers at the University of New South Wales are developing a "reverse solar panel" that generates small amounts of electricity at night by harvesting infrared heat radiated from Earth. "In the past, scientists have demonstrated that a 'thermoradiative diode' can convert infrared radiation directly into electricity; when used to convert heat from Earth, they exploit the temperature difference between Earth and the night sky, generating a current directly from heat," notes ExtremeTech. "This approach completely eliminates the need for heat to generate steam, though the resulting capacity is fairly low." From the report: The researchers estimate they could generate only about a watt per square meter, which isn't much. One reason for the low output is that the Earth's atmosphere lessens the heat differential that drives the generative process; in space, though, that's not an issue.

Now, researchers believe that the ability to generate power in the moments between direct sunlight could help power satellites. That could be especially true in deep space, where periods without sunlight can be longer, and sunlight is often weaker; in these situations, losing electricity to heat loss is unacceptable.

Many satellites already use heat to generate electricity, though with a much more rarified "thermoelectric generator" that uses rare, expensive materials like plutonium to create heat. With thermoradiative diodes, the heat source can be the Sun-warmed body of the satellite itself.

Tim Berners-Lee Wants Us To Take Back the Internet (theguardian.com) 68

mspohr shares a report: When Sir Tim Berners-Lee invented the world wide web in 1989, his vision was clear: it would used by everyone, filled with everything and, crucially, it would be free. Today, the British computer scientist's creation is regularly used by 5.5 billion people -- and bears little resemblance to the democratic force for humanity he intended.

Since Berners-Lee's disappointment a decade ago, he's thrown everything at a project that completely shifts the way data is held on the web, known as the Solid (social linked data) protocol. It's activism that is rooted in people power -- not unlike the first years of the web.

This version of the internet would turbocharge personal sovereignty and give control back to users. Berners-Lee has long seen AI -- which exists only because of the web and its data -- as having the potential to transform society far beyond the boundaries of self-interested companies. But now is the time, he says, to put guardrails in place so that AI remains a force for good -- and he's afraid the chance may pass humankind by.
Berners-Lee traces the web's corruption to the commercialization of the domain name system in the 1990s, when the .com space was "pounced on by charlatans." The 2016 US elections, he said, revealed to him just how toxic his creation could become. A corner of the web, he says, has been "optimised for nastiness" -- extractive, surveillance-heavy, and designed to maximize engagement at the cost of user wellbeing.

His answer is Solid, a protocol that gives users control through personal data "pods" functioning as secure backpacks of information. The Flanders government in Belgium already uses Solid pods for its citizens. On AI, his optimism remains dim. "The horse is bolting," he says, calling for a "Cern for AI" where scientists could collaboratively develop superintelligence under contained, non-commercial oversight.

Pinterest Cuts Up To 15% Jobs To Redirect Resources To AI (reuters.com) 19

Pinterest said on Tuesday it would trim its workforce by less than 15% and reduce office space, as the social media company looks to reallocate resources to AI-focused roles and initiatives. From a report: The announcement comes as the company competes with TikTok and Meta-owned Facebook and Instagram for digital advertising budgets, as these platforms continue to draw marketers with their extensive user base.

Pinterest had 5,205 full-time employees as of September 2025. The latest job cut would translate to less than 780 positions. Top executives at the World Economic Forum's annual meeting said while jobs would disappear, new ones would spring up, with two telling Reuters that AI would be used as an excuse by companies which were planning layoffs anyway. Last week, design software maker Autodesk also announced a 7% job cut to redirect investments to its cloud platform and AI efforts.

Startup Uses SpaceX Tech to Cool Data Centers With Less Power and No Water (yahoo.com) 56

California-based Karman Industries "says it has developed a cooling system that uses SpaceX rocket engine technology to rein in the environmental impact of data centers," reports the Los Angeles Times, "chilling them with less space, less power and no water." Karman has developed a cooling system similar to the heat pumps in the average home, except its pumps use liquid carbon dioxide as refrigerant, which is circulated using rocket engine technology rather than fans. The company's efficient pumps can reduce the space required for data center cooling equipment by 80%.

Over the years, data centers have used fans and air conditioning to blow cold air on the chips. Bigger facilities pass cold liquid through tubes near the chips to absorb the heat. This hot liquid is sent outside to a cooling yard, where sprawling networks of pipes use as much water as a city of 50,000 people to remove the heat. A 50 megawatt data center also uses enough electricity to power a mid-sized city... Cooling systems account for up to 40% of a data center's power consumption and an average midsized data center consumes more than 35,000 gallons of water per day...

U.S. data centers will consume about 8% of all electricity in the country by 2030, according to the International Energy Agency... The cooling systems are projected to use up to 33 billion gallons of water by 2028 per year... To serve this seemingly insatiable market, Karman has developed a rotating compressor that spins at 30,000 revolutions per minute — nearly 10 times faster than traditional compressors — to move heat...

About a third of Karman's 23-person team came from SpaceX or Rocket Lab, and they co-opted technologies from aerospace engineering and electric vehicles to design the mechanics for the high-speed motors. The system uses a special type of carbon dioxide under high pressure to transfer heat from the data center to the outside air. Depending on the conditions, it can do the same amount of cooling using less than half the energy. Karman's heat pump can either reject heat to air, or route it into extra cooling, or even power generation.

The company "recently raised $20 million," according to the article, "and expects to start building its first compressors in Long Beach later this year...."

NASA Confident, But Some Critics Wonder if Its Orion Spacecraft is Safe to Fly (cnn.com) 46

"NASA remains confident it has a handle on the problem and the vehicle can bring the crew home safely," reports CNN.

But "When four astronauts begin a historic trip around the moon as soon as February 6, they'll climb aboard NASA's 16.5-foot-wide Orion spacecraft with the understanding that it has a known flaw — one that has some experts urging the space agency not to fly the mission with humans on board..."

The issue relates to a special coating applied to the bottom part of the spacecraft, called the heat shield... This vital part of the Orion spacecraft is nearly identical to the heat shield flown on Artemis I, an uncrewed 2022 test flight. That prior mission's Orion vehicle returned from space with a heat shield pockmarked by unexpected damage — prompting NASA to investigate the issue. And while NASA is poised to clear the heat shield for flight, even those who believe the mission is safe acknowledge there is unknown risk involved. "This is a deviant heat shield," said Dr. Danny Olivas, a former NASA astronaut who served on a space agency-appointed independent review team that investigated the incident. "There's no doubt about it: This is not the heat shield that NASA would want to give its astronauts." Still, Olivas said he believes after spending years analyzing what went wrong with the heat shield, NASA "has its arms around the problem..."

"I think in my mind, there's no flight that ever takes off where you don't have a lingering doubt," Olivas said. "But NASA really does understand what they have. They know the importance of the heat shield to crew safety, and I do believe that they've done the job." Lakiesha Hawkins, the acting deputy associate administrator for NASA's Exploration Systems Development Mission Directorate, echoed that sentiment in September, saying, "from a risk perspective, we feel very confident." And Reid Wiseman, the astronaut set to command the Artemis II mission, has expressed his confidence. "The investigators discovered the root cause, which was the key" to understanding and solving the heat shield issue, Wiseman told reporters last July. "If we stick to the new reentry path that NASA has planned, then this heat shield will be safe to fly."

Others aren't so sure. "What they're talking about doing is crazy," said Dr. Charlie Camarda, a heat shield expert, research scientist and former NASA astronaut. Camarda — who was also a member of the first space shuttle crew to launch after the 2003 Columbia disaster — is among a group of former NASA employees who do not believe that the space agency should put astronauts on board the upcoming lunar excursion. He said he has spent months trying to get agency leadership to heed his warnings to no avail... Camarda also emphasized that his opposition to Artemis II isn't driven by a belief it will end with a catastrophic failure. He thinks it's likely the mission will return home safely. More than anything, Camarda told CNN, he fears that a safe flight for Artemis II will serve as validation for NASA leadership that its decision-making processes are sound. And that's bound to lull the agency into a false sense of security, Camarda warned.

CNN adds that Dr. Dan Rasky, an expert on advanced entry systems and thermal protection materials who worked at NASA for more than 30 years, also does not believe NASA should allow astronauts to fly on board the Artemis II Orion capsule.

And "a crucial milestone could be days away as Artemis program leaders gather for final risk assessments and the flight readiness review," when top NASA brass determine whether the Artemis II rocket and spacecraft are ready to take off with a human crew.

Study Shows How Earthquake Monitors Can Track Space Junk Through Sonic Booms (apnews.com) 7

A new study shows that earthquake monitoring networks can track falling space debris by detecting the sonic booms produced during atmospheric reentry, sometimes more accurately than radar. The Associated Press reports: Scientists reported Thursday that seismic readings from sonic booms that were generated when a discarded module from a Chinese crew capsule reentered over Southern California in 2024 allowed them to place the object's path nearly 20 miles (30 kilometers) farther south than radar had predicted from orbit. Using this method to track uncontrolled objects plummeting at supersonic speeds, they said, could help recovery teams reach any surviving pieces more quickly -- crucial if the debris is dangerous.

"The problem at the moment is we can track stuff very well in space," said Johns Hopkins University's Benjamin Fernando, the lead researcher. "But once it gets to the point that it's actually breaking up in the atmosphere, it becomes very difficult to track." His team's findings, published in the journal Science, focus on just one debris event. But the researchers already have used publicly available data from seismic networks to track a few dozen other reentries, including debris from three failed SpaceX Starship test flights in Texas. [...]

Fernando is looking to eventually publish a catalog of seismically tracked, entering space objects, while improving future calculations by factoring in the wind's effect on falling debris. In a companion article in Science, Los Alamos National Laboratory's Chris Carr, who was not involved in the study, said further research is needed to reduce the time between an object's final plunge and the determination of its course. For now, Carr said this new method "unlocks the rapid identification of debris fall-out zones, which is key information as Earth's orbit is anticipated to become increasingly crowded with satellites, leading to a greater influx of space debris."

AI Boosts Research Careers But Flattens Scientific Discovery (ieee.org) 64

Ancient Slashdot reader erice shares the findings from a recent study showing that while AI helped researchers publish more often and boosted their careers, the resulting papers were, on average, less useful. "You have this conflict between individual incentives and science as a whole," says James Evans, a sociologist at the University of Chicago who led the study. From a recent IEEE Spectrum article: To quantify the effect, Evans and collaborators from the Beijing National Research Center for Information Science and Technology trained a natural language processing model to identify AI-augmented research across six natural science disciplines. Their dataset included 41.3 million English-language papers published between 1980 and 2025 in biology, chemistry, physics, medicine, materials science, and geology. They excluded fields such as computer science and mathematics that focus on developing AI methods themselves. The researchers traced the careers of individual scientists, examined how their papers accumulated attention, and zoomed out to consider how entire fields clustered or dispersed intellectually over time. They compared roughly 311,000 papers that incorporated AI in some way -- through the use of neural networks or large language models, for example -- with millions of others that did not.

The results revealed a striking trade-off. Scientists who adopt AI gain productivity and visibility: On average, they publish three times as many papers, receive nearly five times as many citations, and become team leaders a year or two earlier than those who do not. But when those papers are mapped in a high-dimensional "knowledge space," AI-heavy research occupies a smaller intellectual footprint, clusters more tightly around popular, data-rich problems, and generates weaker networks of follow-on engagement between studies. The pattern held across decades of AI development, spanning early machine learning, the rise of deep learning, and the current wave of generative AI. "If anything," Evans notes, "it's intensifying." [...] Aside from recent publishing distortions, Evans's analysis suggests that AI is largely automating the most tractable parts of science rather than expanding its frontiers.

Epic and Google Have a Secret $800 Million Unreal Engine and Services Deal (theverge.com) 7

A federal judge revealed a previously undisclosed ~$800 million, six-year partnership between Epic Games and Google tied to Unreal Engine services and joint marketing. It raises questions about whether the deal influenced Epic's willingness to settle its antitrust case over Android. The Verge reports: [California District Judge James Donato] allowed Epic and Google to keep most of the details of the plan under wraps. But during the hearing, he quizzed witnesses, including Epic CEO Tim Sweeney and economics expert Doug Bernheim, on how it might impact settlement talks -- revealing some hints in the process. "You're going to be helping Google market Android, and they're going to be helping you market Fortnite; that deal doesn't exist today, right?" Donato asked Bernheim, who answered in the affirmative. He also described it as a "new business between Epic and Google."

Sweeney's testimony cracked the mystery a little further. He referred to the agreement as relating to the "metaverse," a term Sweeney has used to refer to Epic's game Fortnite. "Epic's technology is used by many companies in the space Google is operating in to train their products, so the ability for Google to use the Unreal Engine more fullsome... sorry, I'm blowing this confidentiality," Sweeney said. Donato then offered a hard dollar figure on one part of the deal: "An $800 million spend over six years, that's a pretty healthy partnership," he said. We soon learned that refers to Epic spending $800 million to purchase some sort of services from Google: "Every year we've decided against Google, in this year we're deciding to use Google at market rates," he said. Sweeney did throw cold water on the idea that Epic and Google are jointly building a single new product together, though. "This is Google and Epic each separately building product lines," he clarified, when Judge Donato asked what the term sheet referred to with the line "Google and Epic will work together."

Donato seemed potentially leery of the partnership, asking Bernheim whether it could constitute a "quid pro quo" that reduced Epic's incentive to push for terms that would benefit other developers. Currently, Epic is backing a settlement that would see Google reduce its standard app store fees worldwide and allow alternative app stores to register for easy installation on Android. Sweeney disputed the notion that Epic might be getting paid off to soften its terms, when it's the one paying out. "I don't see anything crooked about Epic paying Google off to encourage much more robust competition than they've allowed in the past," he said. "We view this as a significant transfer of value from Epic to Google." He also says the Epic Games Store won't get any special treatment from Android in the future under this deal. It appears that the settlement arrangement is tied to the business deal. Judge Donato suggested that Epic and Google would only make the deal if the settlement goes through. Sweeney says the specific terms of the deal have not yet been reached, but admitted that he expects them to. He told Judge Donato that yes, he considers the settlement and deal "an important part of Epic's growth plan for the future."
