  • Workers Spend As Much Time 'Botsitting' AI As Producing Useful Work, Survey Finds
    by EditorDavid on 15/06/2026 at 1:19 am

    "As the use of artificial intelligence spreads across companies worldwide, it is relieving workers of tedious old chores but creating new ones," reports the Los Angeles Times. "Most people don't realize the amount of time that they're spending working on the tools to get the time savings that they're professing," said Paul Leonardi, Duca Family professor of technology management at UC Santa Barbara." Leonardi is one of the co-authors of the new study published by the Work AI Institute, whose contributors include academics from Stanford University and UC Berkeley. The institute is sponsored by AI company Glean... The research surveyed 6,000 digital workers across the United States, the United Kingdom, and Australia between December and January. The report found that we are in a phase of significant personal productivity gains, but few companies are translating these gains into revenue and business growth. While 75% of individuals reported a boost in productivity, only 13% of the organizations say they have seen significant business gains as a result of AI adoption, the survey found... The reason the boost in productivity sometimes leads to waste, Leonardi said, is the time people spend correcting the bot's work and gathering the right files, documentation, and tacit knowledge required for it to produce high-quality output. "It's pretty striking the amount of time and effort people are spending," Leonardi said. Most employees now spend over six hours a week of their workday babysitting their work chatbots, the survey said. There is a "thick, mostly invisible layer of human labor holding the whole thing together," the report said. The survey found that for every hour a worker spends getting useful output from AI, they spend roughly another hour making it usable. Of the total time workers spend interacting with AI each week, 37% goes to botsitting, 36% to actually using the tool to produce work. Part of the reason so much time disappears into botsitting is how often the tools fall short: Workers report that more than a third of AI sessions fail outright, requiring a full restart or substantial rework. Paradoxically, as more workers hand over bigger parts of their jobs to AI, they are offloading personal judgment and responsibilities to the bots. The survey found 41% of workers say they sometimes deliver AI-generated work they couldn't explain if asked... "I think what's happening with a lot of these Gen AI tools right now is we're essentially expecting individual contributors to act as managers," Leonardi said. "They're just managing these AI tools, AI agents, and we're expecting that they'll be able to produce way more, but we're not taking into account all of the work that actually goes into managing." This problem isn't likely to go away. Read more of this story at Slashdot.

  • Microsoft Updates Six Windows Apps. 'Photos' Gets Watermarks for Copilot Images (Off by Default)
    by EditorDavid on 14/06/2026 at 11:15 pm

    Microsoft dropped "massive" updates for six stock Windows apps, reports the "Microsoft enthusiast" site Neowin. Here's some of their more interesting highlights for Clock, Media Player, Calculator, Voice Recorder, Photos, and Paint: The Photos app (version 2026.11060.2004.0): AI watermarking — "AI-generated or edited images can now carry a visible Copilot watermark. You choose Never, Always, or Ask Every Time in Settings, with a confirmation when saving. The watermarking is off by default in settings." Calculator (version 11.2605.9.0): More accurate square-root results. "Fixed rare cases where a calculation that should equal zero (like sqrt(2.25) — 1.5) returned a tiny leftover value instead...." Reliable launch after upgrading. "Fixed an issue where upgrading from much older versions could leave outdated settings that stopped the app from opening..." The Clock app (version 11.2605.9.0): "Timers keep counting after they hit zero — When a timer runs out, it now keeps counting up (for example, -00:27:31) so you can see how far past the time you've gone..." "Correct sun and moon icons during midnight sun — Fixed an icon that wrongly showed a moon during all-day daylight in polar regions... " "No more double announcements — Screen readers no longer read the timer value twice." Media Player (version 11.2605.14.0). "Playlists need a name — You can no longer accidentally save a playlist with a blank name." Read more of this story at Slashdot.

  • UK Scientists See Little Evidence for Claims Smartphones Are Rewiring Kids' Brains
    by EditorDavid on 14/06/2026 at 9:35 pm

    UK's Members of Parliament (MP) were "looking for proof that smartphones and social media are rotting children's brains," writes The Register — but they got "a less satisfying answer from neuroscientists on Wednesday: nobody can really prove it." Appearing before the Science, Innovation and Technology Committee this week, three researchers spent much of the session explaining that concern and evidence are not quite the same thing. Asked what evidence exists on the impact of digital devices on infants and young children, Professor Denis Mareschal, director of the Centre for Brain and Cognitive Development at Birkbeck, replied: "There is very little, if any, causal research in the early years. Almost everything is correlational." MPs kept coming back to the question — and the experts kept coming back to the same answer. When questioned about social media's impact on adolescents, Professor Sarah-Jayne Blakemore of the University of Cambridge was equally cautious. "What evidence do we have of the impact of digital devices or social media on the adolescent brain?" she asked. "Almost nothing. There are a few small studies, but they haven't been replicated, and they're purely correlational...." MPs also wanted to know whether neuroscience could settle one of the liveliest arguments in the debate: how old a child should be before they're allowed onto social media. "What neuroscience can't do is pinpoint a precise age," Blakemore said. "The individual differences in brain development are vast...." If there was a takeaway from the hearing, it was that concern about digital childhood is running well ahead of the evidence needed to settle the argument. Read more of this story at Slashdot.

  • As 'Disclosure Day' Premieres, Steven Spielberg Says He Believes Aliens Really Have Visited Earth
    by EditorDavid on 14/06/2026 at 8:11 pm

    Steven Spielberg grants that his 1977 UFO film Close Encounters was "speculative," writes the Associated Press, but "Disclosure Day, he insists, is the real deal." "It's my first film that will be considered science fiction that I do not consider to be science fiction," Spielberg said in a recent interview. "It's much more reflective of the world as it is evolving and discoveries that are being made as we speak." Spielberg, at 79, is trying to revive and reconsider the alien wonder that's long lingered in his mind, from "E.T." to "War of the Worlds." "Disclosure Day," Spielberg's first summer movie in a decade, is already being hailed as one of his best in years. But this time, Spielberg is testing whether he can conjure some of his trademark movie magic less with imagination than with conviction. "I've been a believer since I made 'Close Encounters' 50 years ago," Spielberg says. "But I would always say: Until I've seen a UAP or a UFO with my own eyes, I'm not going to categorically state that life from out there has come here. But I've changed that," he adds. "I'm now willing to change my mind because of the circumstantial evidence which is overwhelming..." Spielberg, having long followed reports of alleged alien encounters, was inspired by the 2023 House Subcommittee on National Security hearing on UAPs: Unidentified Anomalous Phenomena. Among the witnesses was whistleblower and former Air Force intelligence officer David Grusch, who testified that the government concealed a program investigating UAPs. The Pentagon then denied it... Those 2023 testimonies and others so fueled Spielberg that he produced a 50-page treatment on what would become "Disclosure Day." During the writing process with Koepp, he texted him more notes, he says, "than I've ever sent to anyone in my life." "There was a period in there where I believe he re-read the script every single day for a year," Koepp says. "We'd be in different time zones and I would wake up to 30 or 35 texts from his most current reading of the script. When the leader of the project has that level of commitment, it tends to bring along everyone. You up your game." The article calls it "a grand bookend for one of the most cosmically-minded moviemakers of our time." But the man who filmed some of the world's first summer blockbusters also shared his thoughts on the future of movies. "Even though the numbers are still not pre-COVID level numbers for any films being released now, it's more robust than it has been for many years. The audience gives me belief that people still want to congregate in a dark space in the company of strangers to share an experience of a film made by storytellers. And that gives me faith to continue making films." Rolling Stone wrote that "There's a lot to love in Disclosure Day." Though they also offer this pithy summary of its plot. "Remember when Steven Spielberg digitally replaced the guns in the hands of government agents for the 20th anniversary of E.T., then expressed regret about the decision? Imagine that he not only restored the weapons but crafted an entire two-and-a-half-hour feature around that one sequence as a mea culpa. That's Disclosure Day." The filmmaker may be staging a pulpy campaign with this sci-fi throwback, but he sincerely seems to believe the truth is out there — and will set us free... [W]hile the quality of his output can vary wildly when you look at the big picture of his career, there's still a baseline of love — for filmmaking, for storytelling through images, for giving people an experience that pushes emotional buttons and taps adrenal glands — that gives his work a sense of vitality and displays the sensibility of an artist at work... There's also a weird full-circle feel to it, and not just because he's returning to the fertile ground of Close Encounters and his other science fiction spectacles. You can see traces of everything from Duel to Minority Report show up, to the point where this almost doubles as a career retrospective in miniature... Yes, Spielberg does believe that we are not the only game running in the cosmos. But he also believes that our better angels have not left the building, and that movies still have the power to communally blow minds and open hearts. The Associated Press calls it "a grand bookend for one of the most cosmically-minded moviemakers of our time" and "a distant answer to the final notes of Close Encounters."

  • Will Meta's $14 Billion Bet on AI Ever Pay Off?
    by EditorDavid on 14/06/2026 at 6:43 pm

    "A year after spending over $14 billion to bring in Alexandr Wang and a group of his top Scale AI engineers to revamp its artificial intelligence efforts, Meta is at least back on the map in AI," reports CNBC, "though it's still far behind OpenAI, Anthropic and Google in the market." Wang's big accomplishment was the delivery of the Muse Spark AI model in April, marking Meta's first jump into proprietary foundation models and away from a strict adherence to open source, or open weight as it's more commonly called in AI... "Meta needs to provide more proof points of both adoption and commercialization," said Ralph Schackart, an analyst at William Blair who recommends buying the stock. "Investors are looking for Meta to monetize a new AI-first product, beyond the substantial positive impact AI is having on enhancing the advertising models." Wall Street, at least so far, is unimpressed. Meta's stock is down 18% over the past 12 months, the worst performer in the megacap group, along with Microsoft, which has its own challenges in AI. That's even after Meta reported 33% revenue growth in the first quarter, the fastest rate of expansion for any period since 2021. For Meta, the problem started with what some industry experts called, in hindsight at least, a strategic blunder. The company jumped into AI with its Llama family of models, offering an open-source approach that allowed developers to freely tinker, while the other big model makers charged for access. In April of last year, Meta's release of Llama 4 fell flat, failing to captivate developers and leading Zuckerberg to reconsider his company's approach to AI development... Since the release of Muse Spark, Meta has unveiled new AI and business-related subscription plans as part of an effort to expand its business beyond online ads. Historically, it hasn't worked. Meta still counts on ads for 98% of revenue. Schackart said he wants to see "tangible evidence of a growing list of new, AI-first products created by Muse Spark, even if monetization lags." He said that's "what investors are looking for." No matter how good Wang's model may be, Zuckerberg has a high hill to climb with developers coming off the Llama debacle. "I think the AI community largely ignores Meta at this point," said Rob May, CEO of the startup Neurometric, which works in the realm of token engineering.... Krish Subramanian, the CEO of consulting firm KOI AI and former product head at IBM Consulting, said developers are more excited about Google's AI models than what Meta is offering. The appeal of Llama was that it specifically targeted developers wanting open-weight alternative models, while with Muse Spark, Meta has made little effort in that direction, he said. "The lack of developer trust will come back to hit them if they don't focus on third-party developers," Subramanian said, noting that it took years for Microsoft to regain trust from open-source coders during the early days of Azure. "To just focus on a walled-garden kind of an ecosystem and ad revenue as the main source of income, they probably will never become the big player," he said. A Meta spokesperson pointed to Wang's recent comments about the company's continued support for the open-source ecosystem, and said Meta still plans to offer outside developers access to Muse Spark's underlying technology via an API, as it previously announced. "We're already testing with some early partners, and look forward to releasing it this month," the spokesperson said. "That Zuckerberg's metaverse and virtual reality ambitions have generated over $80 billion in total losses since late 2020 makes the AI pitch a tougher sell," the article points out, citing this observation from Howard Yu, business professor at Switzerland's International Institute for Management Development. "He's running out of the space for his credibility to last," Yu said. "I think the virtual reality foray may have burned up a lot of his goodwill in front of investors."

  • Vintage AMD R600 Graphics Driver Sees Code Cleanups Thanks To GitHub Copilot
    by EditorDavid on 14/06/2026 at 4:34 pm

    Phoronix reports: The AMD R600 Gallium3D driver saw 59 commits [last] Sunday to Mesa 26.2. Making this code restructuring and code cleaning all the more notable is that the improvements to this old AMD Radeon graphics driver was done in part by GitHub Copilot. Gert Wollny has been among the few open-source developers left working on the AMD R600g driver that covers from the Radeon HD 2000 series through Radeon HD 6000 series graphics cards... [T]he old open-source GPU driver support is being assisted by AI long after the upstream vendor has stopped working on this driver — the Radeon HD 2000 "R600" series launched in 2007.
