  • Elon Musk Says OpenAI Betrayed Him, Clashes With Company's Attorney
    by BeauHD on 30/04/2026 at 3:30 am

    An anonymous reader quotes a report from the San Francisco Chronicle: Elon Musk returned to the witness stand Wednesday in Oakland federal court for a second day of testimony in his case against OpenAI, detailing his shift from being an enthusiastic supporter of the nonprofit to feeling betrayed. He also clashed repeatedly with OpenAI's attorney over questions that Musk believed were unfair. He said his feelings towards OpenAI CEO Sam Altman and President Greg Brockman shifted from a "phase one" of support, "phase two" of doubts, and finally "phase three, where I'm sure they're looting the nonprofit. We're currently in phase three," Musk said with a chuckle. Musk said he was a "fool" for giving OpenAI "$38 million of essentially free funding to create what would become an $800 billion company," of which he has no equity stake. In his 2024 lawsuit, Musk alleged breach of charitable trust and unjust enrichment, arguing OpenAI abandoned its original nonprofit mission to benefit humanity to pursue financial gain. OpenAI's lawyer William Savitt argued Tuesday during his opening statement that the nonprofit entity remains in control of the for-profit public benefit corporation and is now one of the most well-funded nonprofits in the world. Musk is seeking to oust Altman from OpenAI's board and upwards of $134 billion in damages, which he said would be used to fund OpenAI's nonprofit mission. During cross-examination, Savitt clashed with Musk over questioning. Savitt asked whether Musk had contributed $38 million to OpenAI, rather than the $100 million that he later claimed to have invested on X. Musk said he also contributed his reputation to the company and came up with the idea for the name, leading Savitt to ask Musk to respond yes or no to "simple" questions. "Your questions are not simple. They're designed to trick me, essentially," Musk said, adding that he had to elaborate or it would mislead the jury. He compared Savitt's questions to asking, "have you stopped beating your wife?" Judge Yvonne Gonzalez Rogers intervened, leading Musk to answer yes to the $38 million investment amount. The world's richest man said his doubts grew and by late 2022, he thought "wait a second, these guys are betraying their promise. They're breaking the deal." "I started to lose confidence that they were telling me the truth," Musk said. A turning point was co-defendent Microsoft's investment of billions of dollars into OpenAI, Musk said. On October 23, 2022, Musk texted Altman that he was "disturbed" to see OpenAI's valuation of $20 billion in the wake of the Microsoft deal. Musk called the deal a "bait and switch," since a nonprofit doesn't have a valuation. OpenAI had "for all intents and purposes" become primarily a for-profit company, Musk argued. Altman responded to Musk by text that "I agree this feels bad," saying that OpenAI had previously offered equity in the company but Musk hadn't wanted it at the time. Altman said the company was happy to offer equity in the future. Musk said it "didn't seem to make sense to me" to hold equity in what should be a nonprofit. Musk also testified about former OpenAI board member Shivon Zilis, who lives with him, is the mother of four of his children, and served as a senior advisor at Neuralink. He denied that she shared sensitive OpenAI information with him. Court evidence showed Musk had encouraged her to stay close to OpenAI to "keep info flowing" and had approved Neuralink recruiting OpenAI employees, which he defended by saying workers are free to change jobs. "It's a free country," Musk said.

  • New Sam Bankman-Fried Trial Would Be Huge Waste of Court's Time, Judge Says
    by BeauHD on 29/04/2026 at 11:00 pm

    A federal judge denied Sam Bankman-Fried's request for a new trial, calling his claims of DOJ witness intimidation "wildly conspiratorial" and unsupported by the record. Judge Lewis Kaplan said (PDF) the FTX founder's motion appeared tied to a pre-indictment plan to recast himself as a Republican victim of Biden's DOJ in hopes of gaining sympathy, leniency, or even a Trump pardon. Ars Technica reports: Bankman-Fried was sentenced to 25 years in prison in 2024 for "masterminding one of the largest financial frauds in American history," US District Judge Lewis Kaplan wrote in his order. He was convicted on all charges, including wire fraud, conspiracy to commit securities fraud, commodities fraud, and money laundering. There is already an appeal pending in another court, the judge noted. But Bankman-Fried filed a separate motion for a new trial, claiming that there were "newly discovered" witnesses and evidence that might have helped his defense, if Joe Biden's Department of Justice hadn't intimidated them into refusing to testify or, in one case, lying on the stand. He also asked for a new judge, wanting Kaplan to recuse himself. However, Kaplan pointed out that "none of the witnesses" were "newly discovered." And more concerningly, Bankman-Fried offered no evidence that the witnesses could prove the "wildly conspiratorial" theory the FTX founder raised, claiming that their absence at the trial was a "product of government threats and retaliation," the judge wrote. Bankman-Fried's theory is "entirely contradicted by the record," Kaplan said. He emphasized that granting Bankman-Fried's request "would be a large waste of judicial resources as it could require another judge to familiarize himself or herself with an extensive and complicated record." Additionally, all three witnesses that Bankman-Fried claimed could give crucial testimony in his defense were known to him throughout the trial, and he never sought to compel their testimony. And the "self-serving social-media posts" of one witness who now claims that he lied when testifying against Bankman-Fried -- "Ryan Salame, who pleaded guilty" -- must be met with "utmost suspicion," Kaplan said. "If one were to take Salame at his current word, he lied under oath when pleading guilty before this Court," Kaplan wrote. Even if taken seriously, "his out-of-court, unsworn statements could not come anywhere close to clearing the bar to warrant a new trial," Kaplan said, deeming Salame's credibility "highly questionable." Further, "even if these individuals had testified for Bankman-Fried, his protestations that one or more of them would have supported his claims that FTX was not insolvent and that his victims all were compensated fully in the bankruptcy proceedings are inaccurate or misleading," Kaplan concluded. In the order, Kaplan's frustration seems palpable, as there may have been no need for him to rule on the motion at all after Bankman-Fried requested to withdraw it. But the judge said the ruling was needed after Bankman-Fried waited to file his withdrawal request until after the DOJ and the court wasted time responding and reviewing filings, the judge said. Troublingly, Bankman-Fried's request to withdraw his request without prejudice would have allowed him to potentially request a new trial after the appeal ended. Based on the substance of the filing, that risked wasting future court resources, Kaplan determined. To prevent overburdening the justice system, Kaplan deemed it necessary to deny Bankman-Fried's motion and request for recusal, rather than allow him to withdraw the filing without prejudice.

  • Ubuntu's AI Plans Have Linux Users Looking For a 'Kill Switch'
    by BeauHD on 29/04/2026 at 10:00 pm

    Canonical's plan to add AI features to Ubuntu has sparked pushback from users who are concerned it could follow Windows 11's AI-heavy direction. "After Canonical's announcement earlier this week that it's bringing AI features to Ubuntu, replies included requests for an AI 'kill switch' or a way to disable the upcoming features," reports The Verge. Canonical says it has no plans for a "global AI kill switch" but it will allow users to remove any AI features they don't want. From the report: In his original post, [Canonical's VP of engineering, Jon Seager] said the upcoming AI features will include accessibility tools like AI speech-to-text and text-to-speech, along with agentic AI features for tasks like troubleshooting and automation. Canonical is also encouraging its engineers to use AI more and plans to begin introducing AI features in Ubuntu "throughout the next year." In a follow-up comment, Seager clarified that, "my plan is to introduce AI-backed features as a 'preview' on a strictly opt-in basis in [Ubuntu version] 26.10. In subsequent releases, my plan is to have a step in the initial setup wizard that allows the user to choose whether or not they'd like the AI-native features enabled." Ultimately, he said, "All of these capabilities will be delivered as Snaps to the OS, layered on top of the existing Ubuntu stack. That means there will always be the option of removing those Snaps." Users who prefer to avoid AI entirely could switch to other distros like Linux Mint, Pop!_OS, or Zorin OS. "These distros have some similarities to Ubuntu, but may not necessarily adopt the new AI features Canonical is rolling out," adds The Verge. Read more of this story at Slashdot.

  • Joby Demos Its Air Taxi In NYC
    by BeauHD on 29/04/2026 at 9:00 pm

    Joby Aviation has completed demonstration flights of its electric air taxi over New York City, testing real routes between JFK and Manhattan helipads as it prepares for a future commercial service. The company says its eVTOL could turn a 60- to 120-minute airport trip into a flight of under 10 minutes, though commercial launch still depends on FAA certification. Electrive reports: To launch operations in New York City, Joby acquired Blade Urban Air Mobility last year. Blade already enables helicopter flights for affluent travelers between Manhattan and airports such as JFK or Newark in just five minutes, avoiding up to two hours of traffic and typical airport hassles. Joby aims to replace this service with quiet, electric air taxis as soon as possible, transitioning Blade's existing customers to the new technology. However, introducing a new aircraft into commercial service requires a years-long certification process, overseen in the US by the Federal Aviation Administration (FAA). Joby is now in the final phase of FAA certification. Following a series of demonstration flights in the San Francisco Bay Area, the company has tested its air taxi in New York City on real flight routes and under real-world conditions. During these tests, Joby demonstrated the acoustics and performance metrics critical for entering the urban air taxi market. During these demonstration flights, Joby's air taxi took off from John F. Kennedy International Airport (JFK) and landed at various helipads across the city, including Downtown Skyport and the helipads at West 30th Street and East 34th Street in Midtown, where Blade Air Mobility's premium passenger lounges are located. These locations represent some of the commercial routes Joby plans for New York [...]. Fun fact: Joby's eVTOL aircraft are over 100 to 1,000 times quieter than a conventional helicopter, operating at roughly 55-65 dB during takeoff and landing compared to 90+ dB for helicopters.

  • Apple Gives Up On the Vision Pro After M5 Refresh Flop
    by BeauHD on 29/04/2026 at 8:00 pm

    MacRumors reports that Apple has effectively paused work on Vision Pro after the M5 refresh failed to revive demand. The team has reportedly been reassigned and the company is now shifting focus toward smart glasses instead. From the report: The Vision Pro has been criticized for its high price tag and its uncomfortable weight. The device is over 1.3 pounds, and even with the more comfortable Dual Knit Band that Apple added to redistribute weight, it continues to be hard to wear for long periods of time. The M5 chip added a 120Hz refresh rate, 10 percent more rendered pixels, and around 30 additional minutes of battery life, but the price tag stayed at $3,499, and it ended up not selling well. The Vision Pro has been unpopular since it first launched, and Apple only sold around 600,000 units in total. Insider sources told MacRumors that Apple has received an unusually high percentage of returns, far exceeding any other modern Apple product. [...] If Apple finds a way to create a much cheaper, more comfortable VR headset in the future, the Vision Pro line could be revived, but right now, the company has no plans to launch a new model. Apple has not discontinued the Vision Pro and is continuing to sell the M5 model. Instead of continuing to experiment with virtual reality, Apple is working on smart glasses that will eventually incorporate augmented reality capabilities, but the first version will be similar to the Ray-Ban Meta smart glasses with AI and no integrated display.

  • California High-Speed Rail Price Tag Jumps To $231 Billion
    by BeauHD on 29/04/2026 at 7:00 pm

    Longtime Slashdot reader schwit1 writes: California's long-delayed high-speed rail project is now facing renewed scrutiny after state leaders revealed a dramatically higher price tag, now estimated at roughly $231 billion, nearly seven times the original $33 billion projection approved by voters in 2008. The revised figures have reignited talks in Sacramento over whether the project can realistically be completed, how long it will take, and whether the state can continue to fund it at this scale. Senator Strickland pointed to comments from Lou Thompson, former chair of the California High-Speed Rail Authority peer review group, who recently criticized the latest draft business plan. Thompson wrote that the 2026 draft plan "has reached a dead end," arguing that the project has drifted far from its original vision due to escalating costs, delays, and unfunded gaps. Under current projections, assuming funding and construction proceed as planned, service between San Francisco and Bakersfield could begin around 2033, while the full Los Angeles to San Francisco connection could extend to 2040.
