  • OpenAI's Altman Says the Use of AI is 'Non-Negotiable'
    by BeauHD on 02/09/2026 at 8:00 pm

    OpenAI CEO Sam Altman said AI adoption is "non-negotiable" for countries, comparing rejecting it to refusing electricity a century ago and predicting it will unleash an unprecedented boom in entrepreneurship. "The economic growth and benefit to people that can come from this, the value to a country, is too high to ignore," he said. His comments were made during a fireside chat with U.S. Commerce Secretary Howard Lutnick at the G20 Innovation Ministerial in Chapel Hill, North Carolina. CNBC reports: Altman thinks the public won't be talking as much about AI a decade from now -- it'll be expected everywhere. "A kid growing up today will never be smarter than AI, but he or she will also never have understood a world where every product and service that they interact with is not really smart and really capable and really helpful," he said. Altman referenced the adoption of electricity multiple times in his comments and drew a line between that and AI. "I think it would be approximately as bad of an idea to say we're not going to have AI in our country as it was to say we're not going to have electricity in our country, you know, back 100 plus years ago," he said. Altman called cybersecurity one of the biggest challenges to navigate in the age of AI and one that leaders shouldn't sidestep. "I think some things are going to go very wrong with cybersecurity unless people act quite urgently," he said. Altman said that falling short in cyber defense and other areas "could set this technology back a great deal." You can watch a recording of the chat on YouTube. Read more of this story at Slashdot.

  • NYC Public Schools Ban AI Use Through Middle School
    by BeauHD on 02/09/2026 at 7:00 pm

    New York City Public Schools is banning generative AI for students from pre-K through eighth grade for the 2026-27 school year, affecting more than half a million students in the nation's largest school district. ABC News reports: In a statement to ABC News, New York City Mayor Zohran Mamdani said that the city is implementing a moratorium on generative AI for students in pre-school or 2-K through eighth grade and will spend the next year "studying the impacts of this technology." Mamdani wrote in part, "the tech industry wants us to believe that A.I.-powered early education is not only inevitable, but necessary." "We do not see it that way," he added. [...] The district said it is implementing the most expansive AI moratorium in the nation, eliminating software that uses student-facing AI and banning companion chatbots. The city's AI moratorium does not apply to high school students. The district said it will offer twice-yearly AI literacy classes designed to help high school students "think critically" about the technology before they start to "rely" on it.

  • Google Defeats US Bid to Force Ad Tech Sale
    by BeauHD on 02/09/2026 at 6:00 pm

    An anonymous reader quotes a report from Reuters: Alphabet's Google escaped a breakup of its advertising technology business on Wednesday, when a judge in Virginia rejected U.S. antitrust enforcers' bid to force a sale of Google's online advertising exchange. While the ad exchange is a small part of Google's business, the ruling is the second powerful symbolic victory against the U.S. Department of Justice in its efforts to force Google to sell assets to address illegal monopolies. U.S. Judge Leonie Brinkema in Alexandria, Virginia, declined to make Google sell AdX, where publishers pay Google a 20% fee to sell ads in auctions that happen instantly when users load websites. She accepted most of the parties' proposed behavioral remedies. The DOJ and a broad coalition of states sued Google in 2023 over its dominance in markets for advertising technology used by online publishers and websites. In April 2025, Brinkema ruled that Google holds illegal monopolies on servers that host publisher ads and ad exchanges which sit between buyers and sellers. Google unlawfully locked publishers on its ad server into using its AdX, the judge found. The tech giant's anticompetitive conduct "substantially harmed Google's publisher customers, the competitive process, and, ultimately, consumers of information on the open web," Brinkema said at the time. At a trial last year on remedies in the case, the DOJ argued that Google cannot be trusted to run AdX, given its past behavior. Google argued that a forced sale would be technically difficult and result in a long and painful transition that would hurt customers. During the remedies trial, Google's lawyers warned that forcing it to sell parts of its ad-tech business would cause disruption and damage. [...] The ruling is the third time in a row that a judge has rejected a bid by U.S. antitrust enforcers to break up Big Tech in a crackdown that started during President Donald Trump's first term. In another major Google antitrust case, a judge similarly rejected the DOJ's push to force Google to sell Chrome. It is likely to fuel questions about whether courts are up to the task of checking the industry's unprecedented power over the U.S. economy. Read more of this story at Slashdot.

  • Uber Is Laying Off 10% of Its Workforce
    by BeauHD on 02/09/2026 at 5:00 pm

    Uber is laying off about 3,300 employees, or roughly 10% of its workforce, as part of a restructuring aimed at cutting management layers and redirecting investment toward ridesharing, delivery, and robotaxis. CEO Dara Khosrowshahi announced the changes in an internal email that was also published online.TechCrunch reports: According to the email, the layoffs are part of a restructuring exercise that would shrink the number of managers by 20%, and some personnel in these roles would work as individual contributors going forward. The ridesharing giant is reducing the number of teams with one or two members by 50%, and letting go staff who are "more than seven layers down from the CEO," per Bloomberg. Khosrowshahi's email said the company is combining its engineering, science, and delivery divisions. The company is also bringing together its delivery operations across restaurants, retail, and direct divisions. Remote jobs at the company are going away, too, with Uber only allowing less than 1% of its staff to work remotely. Read more of this story at Slashdot.

  • FBI Probes Service Selling 153M+ Drivers Licenses
    by BeauHD on 02/09/2026 at 4:00 pm

    A dark-web identity theft service called Nexus claims to be selling scans of more than 153 million U.S. and Canadian driver's licenses, along with millions of other identity documents. "Based on interviews with individuals whose licenses are available for purchase through the service, it appears to be siphoning images collected by a widely used Louisiana-based identity verification company," reports KrebsOnSecurity. The outlet also reports that the FBI's New Orleans field office has launched an official inquiry into the source of the images. From the report: On Monday, Aug. 31, a source alerted KrebsOnSecurity to a service advertised by a new user on the Russian cybercrime forum Exploit, offering access to digital scans of identity documents on more than 170 million people in North America. The source brought it to my attention because the proprietor of this identity theft service offered my Virginia drivers license as a free sample in their initial sales thread on Exploit. The service, dubbed Nexus, claims to have more than 153 million drivers licenses for people in the United States and Canada, as well as more than 10 million identification cards; more than three million travel documents and/or international IDs; and at least 579,000 medical cards. [...] The people behind Nexus claim the license images are coming from an active breach at "a major identity verification company" whose customers include multiple Fortune 500 companies. "We have been continuously exfiltrating new data for over a year into our private database," the service enthused in its introductory post on Exploit. "Records are available to preview before purchase with pertinent information redacted. Customer photos are displayed if available." Indeed, over the past 24 hours, the number of drivers license records listed as available in Nexus has increased by nearly 400,000, suggesting that freshly stolen license data is being harvested and uploaded to this service on a semi-regular basis. KrebsOnSecurity traced the apparent source by comparing timestamps on stolen license images with when their owners had their IDs scanned, including at Hertz rental counters and a Planet13 dispensary. Both companies use identity-verification services from Louisiana-based idscan.net, whose technology also scans IDs using infrared and ultraviolet light. Since the story was published, Krebs reports that the Nexus identity theft service website "vanished from the darkweb, replacing its login page with a plain text message that reads, 'This service is no longer available.'"
