  • 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.

  • How America's Energy Department is Building a National Platform for Doing Science with AI
    by EditorDavid on 14/06/2026 at 3:34 pm

    America's Energy Department "wants to build a single national platform for doing science with AI," reports Communications of the ACM: It is called the Genesis Mission, and the idea is to connect the country's 17 national laboratories, their supercomputers, scientific datasets, and a growing layer of AI models and agents into one system researchers can access. The DOE has taken to calling it 'a national operating system for science.' That means treating compute, data, and AI models the way the country treats power lines and highways, as shared national plumbing everyone else builds on top of. If it works, Genesis will change how scientific work gets organized, checked, and scaled, with AI helping run the whole pipeline from hypothesis to simulation to experiment and back. The pitch is that this is better understood as infrastructure policy than as another research program. Genesis is now moving from announcement into execution. President Trump signed the executive order launching it in November 2025. This past February, the DOE published 26 science and technology challenges for the program, and in March it opened a $294-million call for research teams in fields like nuclear energy, quantum information science, semiconductors, and biotechnology. The program is also beginning to reach beyond U.S. borders. In June 2026, Japan moved to become Genesis's first international partner. The two governments plan to invest a combined $1 billion over five years, with Japan contributing $500 million toward joint work in quantum technology, nuclear fusion, and biotechnology. The stated goal is staying ahead of China in the fields where AI is advancing fastest. The open question is whether a federated platform this big can actually work, or whether it ends up as one more expensive coordination exercise. Read more of this story at Slashdot.

  • Blizzard Sues To Take Down Another Private World of Warcraft Server, Project Ascension
    by EditorDavid on 14/06/2026 at 2:34 pm

    "Blizzard Entertainment is continuing its crusade against private World of Warcraft servers," reports the gaming news site Aftermath: The company filed a new lawsuit on Friday in a California court against the makers of Project Ascension, alleging copyright infringement, Digital Millennium Copyright Act violations, and other claims. Blizzard Entertainment claims that Project Ascension is a "lucrative way to exploit and profit from the popularity of the WoW game experience," according to the complaint, obtained by Aftermath. Blizzard Entertainment's lawyers say in the complaint that Project Ascension purports to have "over a million players." Lawyers write that the developers have "distributed (and are continuing to distribute) millions of pirated copies of Blizzard's copyrighted WoW game software." They also allege that Project Ascension's servers are hosted on Russian "bulletproof" servers with Aeza Group, a company that was sanctioned in 2025 "for its role in supporting cybercriminal activity targeting victims in the United States and around the world," per a U.S. Department of Treasury press release... Project Ascension lets players combine pieces of World of Warcraft's different classes to build unique characters. It's free-to-play, but players can purchase in-game currency, Donation Points, to buy things in-game, such as cosmetics and experience boosts. Blizzard Entertainment's lawyers assert that Project Ascension has made "millions of dollars from the sale of Donation Points...." Blizzard Entertainment successfully sued a popular World of Warcraft server called Turtle Wow last year. The project had been running since 2018, taking donations from players for the free-to-play server. Both sides announced in April 2026 that they'd reached a settlement after Blizzard Entertainment was awarded a permanent injunction to shut down Turtle WoW. The details of the settlement were not made public. Turtle WoW was shut down for good shortly after May 15; players gathered online to mourn the end of the server.

  • Bitcoin Has Lost Nearly Half Its Value in 11 Months
    by EditorDavid on 14/06/2026 at 11:34 am

    The price of bitcoin dropped 13% down to $64,394 just in June — but there's more bad news, reports CNBC." "Bitcoin has lost nearly half its value since reaching a record high above $123,000 in July 2025." While previous bitcoin selloffs were often followed by large rebounds in price, the latest decline may prompt some investors to revisit why they own bitcoin in the first place, [says Daniel Sotiroff, associate director of ETF and Passive Strategies Research at Morningstar]. Here's what he and other experts have to say about the case for holding crypto, and how much exposure is appropriate for the average investor... Not all financial professionals agree bitcoin belongs in a portfolio. Bitcoin differs from stocks, bonds and real estate because it doesn't generate earnings, interest payments or rental income that investors can use to estimate its value, says Robert Johnson, a finance professor at Creighton University. Instead, its price is largely determined solely by investor demand. "You cannot invest in Bitcoin, you can only speculate," he says. Sotiroff agrees that bitcoin is difficult to value using traditional financial metrics. "The best analogy I've heard is that it's more like a collectible, because it's basically worth what other people are going to pay for it," he says. Sotiroff told CNBC the recent selloff was a reminder that bitcoin's gains can be accompanied by equally dramatic declines — one reason many financial planners recommend limiting exposure to a small portion of a broader portfolio. "You just really can't make a call on what direction it's going to go," says Sotiroff. Read more of this story at Slashdot.
