    U.S. Adds Export Restrictions to More Chinese Tech Firms Over Security Concerns

    by

    The additions included companies that are customers of Intel and Nvidia, and one firm that was the focus of a New York Times investigation last year.The Trump administration on Tuesday added 80 companies and organizations to a list of companies that are barred from buying American technology and other exports because of national security concerns.The move, which targeted primarily Chinese firms, cracks down on companies that have been big buyers of American chips from Nvidia, Intel and AMD. It also closed loopholes that Trump administration officials have long criticized as allowing Chinese firms to continue to advance technologically despite U.S. restrictions.One company added to the list, Nettrix Information Industry, was the focus of a 2024 investigation by The New York Times that showed how some Chinese executives had bypassed U.S. restrictions aimed at cutting China off from advanced chips to make artificial intelligence.Nettrix, one of China’s largest makers of computer servers that are used to produce artificial intelligence, was started by a group of former executives from Sugon, a firm that provided advanced computing to the Chinese military and built a system the government used to surveil persecuted minorities in the western Xinjiang region.In 2019, the United States added Sugon to its “entity list,” restricting exports over national security concerns. The Times investigation found that, six months later, the executives formed Nettrix, using Sugon’s technology and inheriting some of its customers. Times reporters also found that Nettrix’s owners shared a complex in eastern China with Sugon and other related companies.After Sugon was singled out and restricted by the United States, its longtime partners — Nvidia, Intel and Microsoft — quickly formed ties with Nettrix, the investigation found.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      When It Comes to Investing, Is A.I. Worth the Hype?

      by

      After the arrival of a less costly A.I. model from China, U.S. markets and academics are wrestling with the ultimate economic value of the technology.A.I. chatbots are fun, sometimes even useful and, until recently, endowed with the uncanny ability to mesmerize investors and fuel the U.S. stock market.But the excellent performance of a new, relatively cheap artificial intelligence engine from a Chinese start-up, DeepSeek, has perturbed the market and complicated the A.I. story.Investors are re-evaluating prominent companies swept up in A.I. fever, including Nvidia, Meta, Alphabet, Microsoft, Amazon, Tesla and the private start-up OpenAI. The notion that full-blown superhuman intelligence is imminent has spurred the-sky-is-the-limit valuations, as well as concerns about the political and social risks posed by advanced intelligence.One immediate question: Is the main approach to developing A.I. in the United States — pouring billions of dollars into chips and infrastructure — worth the expenditure for all companies if similar results can be achieved far more cheaply? DeepSeek’s lower-cost innovations add urgency to bigger, longstanding financial questions: How much are artificial intelligence companies really worth, and what will the broader economic value of A.I. ultimately be?Daren Acemoglu, a winner of the 2024 Nobel in economic science, gave me some answers. “There is a lot of hype in the industry,” he told me in a telephone conversation. Yes, he said, A.I. companies have made some “impressive achievements,” but he added that many financial and economic calculations were being based on mere “projections into the future that are sometimes exaggerated.”Professor Acemoglu, an M.I.T. economist with an interest in the impact of technical innovations on global economics, is skeptical about the more fervent A.I. claims. He ranks A.I. as a significant advance, perhaps with a macroeconomic effect akin to the telephone, which was no small thing.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Sam Altman on Microsoft, Trump and Musk

      by

      The OpenAI C.E.O. spoke with Andrew Ross Sorkin at the DealBook Summit.Since kicking off the artificial intelligence boom with the launch of ChatGPT in 2022, OpenAI has amassed more than 300 million weekly users and a $157 billion valuation. Its C.E.O., Sam Altman, addressed whether that staggering pace of growth can continue at the DealBook Summit last week.Altman pushed back on assertions that progress in A.I. is becoming slower and more expensive; on reports that the company’s relationship with its biggest investor, Microsoft, is fraying; and on concerns that Elon Musk, who founded an A.I. company last year, may use his relationship with President-elect Donald Trump to hurt competitors.Altman said that artificial general intelligence, the point at which artificial intelligence can do almost anything that a human brain can do, will arrive “sooner than most people in the world think.” Here are five highlights from the conversation.On Elon MuskMusk, who co-founded OpenAI, has become one of its major antagonists. He has sued the company, accusing it of departing from its founding mission as a nonprofit, and started a competing startup called xAI. On Friday, OpenAI said Musk had wanted to turn OpenAI into a for-profit company in 2017 and walked away when he didn’t get majority equity. Altman called the change in the relationship “tremendously sad.” He continued:I grew up with Elon as like a mega hero. I thought what Elon was doing was absolutely incredible for the world, and I’m still, of course, I mean, I have different feelings about him now, but I’m still glad he exists. I mean that genuinely. Not just because I think his companies are awesome, which I do think, but because I think at a time when most of the world was not thinking very ambitiously, he pushed a lot of people, me included, to think much more ambitiously. And grateful is the wrong kind of word. But I’m like thankful.You know, we started OpenAI together, and then at some point he totally lost faith in OpenAI and decided to go his own way. And that’s fine, too. But I think of Elon as a builder and someone who — a known thing about Elon is that he really cares about being ‘the guy.’ But I think of him as someone who, if he’s not, that just competes in the market and in the technology, and whatever else. And doesn’t resort to lawfare. And, you know, whatever the stated complaint is, what I believe is he’s a competitor and we’re doing well. And that’s sad to see.Altman said of Musk’s close relationship with Trump:I may turn out to be wrong, but I believe pretty strongly that Elon will do the right thing and that it would be profoundly un-American to use political power to the degree that Elon has it to hurt your competitors and advantage your own businesses. And I don’t think people would tolerate that. I don’t think Elon would do it.On OpenAI’s relationship with MicrosoftMicrosoft, OpenAI’s largest investor, has put more than $13 billion into the company and has an exclusive license to its raw technologies. Altman once called the relationship “the best bromance in tech,” but The Times and others have reported that the partnership has become strained as OpenAI seeks more and cheaper access to computing power and Microsoft has made moves to diversify its access to A.I. technology. OpenAI expects to lose $5 billion this year because of the steep costs of developing A.I.At the DealBook Summit, Altman said of the relationship with Microsoft, “I don’t think we’re disentangling. I will not pretend that there are no misalignments or challenges.” He added:We need lots of compute, more than we projected. And that has just been an unusual thing in the history of business, to scale that quickly. And there’s been tension on that.Some of OpenAI’s own products compete with those of partners that depend on its technologies. On whether that presents a conflict of interest, Altman said:We have a big platform business. We have a big first party business. Many other companies manage both of those things. And we have things that we’re really good at. Microsoft has things they’re really good at. Again, there’s not no tension, but on the whole, our incentives are pretty aligned.On whether making progress in A.I. development was becoming more expensive and slower, as some experts have suggested, he doubled down on a message he’d previously posted on social media: “There is no wall.” Andrew asked the same question of Sundar Pichai, the Google C.E.O., which we’ll recap in tomorrow’s newsletter.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Emerging Details of Chinese Hack Leave U.S. Officials Increasingly Concerned

      by

      Leaders of the big telecommunications companies were summoned to the White House to discuss strategies for overhauling the security of the nation’s telecommunications networks amid growing alarm at the scope of a Chinese hack. Leaders of the top telecommunications companies were summoned to the White House on Friday to discuss a security problem that has been roiling the government: how to expel Chinese hackers from the deepest corners of the nation’s communications networks.The meeting in the Situation Room came after weeks in which officials grew increasingly alarmed by what they had uncovered about the hack.They now believe the hackers from a group called “Salt Typhoon,” closely linked to China’s Ministry of State Security, were lurking undetected inside the networks of the biggest American telecommunications firms for more than a year.They have learned that the Chinese hackers got a nearly complete list of phone numbers the Justice Department monitors in its “lawful intercept” system, which places wiretaps on people suspected of committing crimes or spying, usually after a warrant is issued.While officials do not believe the Chinese listened to those calls, the hackers were likely able to combine the phone numbers with geolocation data to create a detailed intelligence picture of who was being surveilled.As a result, officials said, the penetration almost certainly gave China a road map to discover which of China’s spies the United States has identified and which they have missed.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      China’s Hacking Reached Deep Into U.S. Telecoms

      by

      The chairman of the Senate Intelligence Committee said hackers listened to phone calls and read texts by exploiting aging equipment and seams in the networks that connect systems.China’s recent breach of the innermost workings of the U.S. telecommunications system reached far deeper than the Biden administration has described, the chairman of the Senate Intelligence Committee said on Thursday, with hackers able to listen in on telephone conversations and read text messages.“The barn door is still wide open, or mostly open,” the Democratic chairman, Senator Mark Warner of Virginia, a former telecommunications executive, said in an interview on Thursday.Mr. Warner said he had been stunned by the scope and depth of the breach, which was engineered over the past year by a group linked to Chinese intelligence that has been named Salt Typhoon by Microsoft, whose cybersecurity team discovered the hack in the summer. Government officials have been struggling to understand what China obtained and how it might have been able to monitor conversations held by a number of well-connected Americans, including President-elect Donald J. Trump and Vice President-elect JD Vance.At first, the F.B.I. and other investigators believed that China’s hackers used stolen passwords to focus mostly on the system that taps telephone conversations and texts under court orders. It is administered by a number of the nation’s telecommunications firms, including the three largest — Verizon, AT&T and T-Mobile. But in recent days, investigators have discovered how deeply China’s hackers had moved throughout the country by exploiting aging equipment and seams in the networks connecting disparate systems.U.S. officials said that since the hack was exposed, the Chinese intruders had seemingly disappeared, suspending their intrusion so their full activity could not be discovered. But Mr. Warner said it would be wrong to conclude that the Chinese had been ousted from the nation’s telecommunications system, or that investigators even understood how deeply they were embedded.“We’ve not found everywhere they are,” Mr. Warner said.The committee has received briefings from the government on the hack, and Mr. Warner has had conversations with telecommunications executives.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Microsoft and OpenAI’s Close Partnership Shows Signs of Fraying

      by

      The “best bromance in tech” has had a reality check as OpenAI has tried to change its deal with Microsoft and the software maker has tried to hedge its bet on the start-up.Last fall, Sam Altman, OpenAI’s chief executive, asked his counterpart at Microsoft, Satya Nadella, if the tech giant would invest billions of dollars in the start-up.Microsoft had already pumped $13 billion into OpenAI, and Mr. Nadella was initially willing to keep the cash spigot flowing. But after OpenAI’s board of directors briefly ousted Mr. Altman last November, Mr. Nadella and Microsoft reconsidered, according to four people familiar with the talks who spoke on the condition of anonymity.Over the next few months, Microsoft wouldn’t budge as OpenAI, which expects to lose $5 billion this year, continued to ask for more money and more computing power to build and run its A.I. systems.Mr. Altman once called OpenAI’s partnership with Microsoft “the best bromance in tech,” but ties between the companies have started to fray. Financial pressure on OpenAI, concern about its stability and disagreements between employees of the two companies have strained their five-year partnership, according to interviews with 19 people familiar with the relationship between the companies.That tension demonstrates a key challenge for A.I. start-ups: They are dependent on the world’s tech giants for money and computing power because those big companies control the massive cloud computing systems the small outfits need to develop A.I.No pairing displays this dynamic better than Microsoft and OpenAI, the maker of the ChatGPT chatbot. When OpenAI got its giant investment from Microsoft, it agreed to an exclusive deal to buy computing power from Microsoft and work closely with the tech giant on new A.I.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Can Math Help AI Chatbots Stop Making Stuff Up?

      by

      Chatbots like ChatGPT get stuff wrong. But researchers are building new A.I. systems that can verify their own math — and maybe more.On a recent afternoon, Tudor Achim gave a brain teaser to an A.I. bot called Aristotle.The question involved a 10-by-10 table filled with a hundred numbers. If you collected the smallest number in each row and the largest number in each column, he asked, could the largest of the small numbers ever be greater than the smallest of the large numbers?The bot correctly answered “No.” But that was not surprising. Popular chatbots like ChatGPT may give the right answer, too. The difference was that Aristotle had proven that its answer was right. The bot generated a detailed computer program that verified “No” was the correct response.Chatbots like ChatGPT from OpenAI and Gemini from Google can answer questions, write poetry, summarize news articles and generate images. But they also make mistakes that defy common sense. Sometimes, they make stuff up — a phenomenon called hallucination.Mr. Achim, the chief executive and co-founder of a Silicon Valley start-up called Harmonic, is part of growing effort to build a new kind of A.I. that never hallucinates. Today, this technology is focused on mathematics. But many leading researchers believe they can extend the same techniques into computer programming and other areas.Because math is a rigid discipline with formal ways of proving whether an answer is right or wrong, companies like Harmonic can build A.I. technologies that check their own answers and learn to produce reliable information.Google DeepMind, the tech giant’s central A.I. lab, recently unveiled a system called AlphaProof that operates in this way. Competing in the International Mathematical Olympiad, the premier math competition for high schoolers, the system achieved “silver medal” performance, solving four of the competition’s six problems. It was the first time a machine had reached that level.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      He Made a Game About a Joyous Journey. He Also Got a Bit Lost.

      by

      Anthony Tan was 16 when his idea for a video game about a deer caught the industry’s eye. Nine years later, he’s still working on it.Anthony Tan’s hands shook as he took his seat in a dark Los Angeles theater. The neon green lights sporadically illuminated the 7,000 faces around him.Tan, a solo video game developer, was just 20 years old. Yet a trailer for his game, Way to the Woods, was about to share screen time with dozens of other coming Xbox titles, including those from mega-franchises like Gears of War and Halo. Unlike those games, created by teams of hundreds with eight- or nine-figure budgets, Tan had built his alone in his spare time, buoyed by grant funding.By the time he sat down in the theater at Microsoft’s annual hype-building event, in June 2019, Tan had watched his trailer more than 100 times. He knew every note, every camera pan. As the lights dimmed and the screen faded to black, he was too nervous to look. Everyone else watched his game’s stars — a deer and a fawn — appear onscreen, pushing a railway handcar across a golden plain.Even before the event was over, Tan’s phone blew up with Twitter messages from strangers. Millions of people had been watching the livestream online. Some praised the game’s art style, which Tan said was inspired by the Studio Ghibli movies “Princess Mononoke” and “Spirited Away”; others were intrigued by its unusual main characters.Tan was now shaking from adrenaline, not nerves.“It was absolutely exhilarating,” he said.Tan’s game about animals navigating an abandoned world had struck a chord. The final seconds of his stylish, mysterious trailer made a promise, or as close to one as the world of video game development allows: “Coming 2020 … for real this time.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
