  • Trump Denounces Attempts to Control AI, Wants It Renamed 'Super Intelligence' in US Documents
    by EditorDavid on 23/09/2026 at 2:34 am

    U.S. President Trump addressed the United Nations on Tuesday. And a half hour in, after decrying immigration, Trump pivoted to add that "The United States also totally rejects any attempt to construct a globalist scheme to control for the artificial intelligence being spoken of so much now." But then he added "hereinafter officially called super intelligence, changing the name, in that the use of the word artificial makes intelligence fake. It makes it sound fake, and it is not fake. It's actually... amazing. But we have to be careful — in fact, it is exactly the opposite of what it purports. From this point forward, all of United States documents and hopefully the world's will be changed to use the much more accurate term super as opposed to artificial. So it's super intelligence." TRUMP: In other words, welcome to the new world of super intelligence — SI. SI. Let's see if that goes. It sounds much better. It is much better, and it's much more accurate. Let's see if I have any power. Maybe I do and maybe I don't. We're going to find out pretty soon. Super intelligence. Every major new technology brings challenges, and super intelligence is no exception. Yet the very same people who said we'll all be dead in 12 years because of global warming, a name since reborn to climate change because the planet was cooling not warming, and nobody was dead — these are the same people that are now saying that AI is going to kill us all. That robots are going to attack us, and that everything is going to be a total disaster — same group of people. This is the group that came up with the Russia Russia Russia hoax, the Ukraine Ukraine Ukraine hoax. Climate change, open borders. Whoever wins AI — you have to remember this — and now I say, whoever wins SI, whoever wins super intelligent [sic] — wins. That's the group that wins. And we're leading now over China by a lot, and everyone else, and we're going to keep it that way. We're going to keep it very — very straight and very strong. I'm not going to stifle growth of something that will be bigger than the Industrial Revolution. Many say, bigger than the Industrial Revolution or the internet itself. And we will be very careful, and that's why we have a Department of Justice that we've already used it, having to do with this very subject, and used it very powerfully. Everything worked out very well and very quickly. And other law enforcement bodies that will rein things in if we have to do that. But we will only encourage super intelligence. We're gonna encourage it, not rein it in. We're gonna watch it closely, through the Department of Justice. The United States leads the world in Super Intelligence, and will continue to do so, safely and responsibly. Thanks to long-time Slashdot reader ArchieBunker for suggesting the story.

  • Are Students Suddenly Losing Interest in Computer Science as AI Coding Takes Off?
    by EditorDavid on 22/09/2026 at 10:04 pm

    On academic mentoring platform Nova Learning, Computer Science and AI, "once the dominant choice among students... is losing ground fast, while Engineering has nearly doubled its share." It's a small survey, but "The steepest proportional decline is in Software & Data Science, the most traditional 'learn to code' pathway, which lost 44% of its 2025 share. AI saw the largest absolute drop of any single subject in the survey, down 6.2 points. "The category did not decline uniformly. Students moved away fastest from the pathway most associated with entry-level software work, while the more applied and human-facing subfields held their ground better." Slashdot reader BrianFagioli writes: Nova Learning says the share of surveyed middle and high school students naming Computer Science and AI as their primary academic interest fell from 42.3 percent in 2025 to 27.9 percent in 2026, while Engineering rose from 11.9 percent to 23 percent. The biggest gains came from Mechanical and Aerospace Engineering... [B]roader enrollment data points in the same direction. The National Student Clearinghouse Research Center reported declines in Computer and Information Science enrollment at four year institutions, even as Engineering grew. AI coding tools are not proven to be the cause, but as software development changes and AI handles more coding tasks, students may be starting to rethink what a future in technology should look like. [Undergraduate enrollment in CS programs at four-year institutions fell 8.1%, to approximately 606,000 students.] Read more of this story at Slashdot.

  • 'Coyote vs. Acme' Outgrosses All But 3 WB Movies This Year, Heads To Profit
    by EditorDavid on 22/09/2026 at 5:34 pm

    The movie Coyote vs. Acme earned more than Warner Bros.' $30 million tax write-off in just two weeks. And last week the movie officially earned more than its production budget of $70 million. But today the movie passed the $100 million mark. "You asked for it, we delivered, and you showed up!" distributor Ketchup Entertainment posted on social media (adding "Thank you to the fans for making this a massive hit!") With a break-even number of $120 million, the movie "will probably make up any theatrical deficit (should there be any) with its impending releases on video on demand and streaming," writes ScreenRant. Almost three years after the completed film was initially shelved for a $30 million write-off, its cumulative domestic box office has apparently even beat Warner Bros. dinosaur movie The End of Oak Street: In addition to officially joining the chart of the Top 30 movies of the year so far at the domestic box office, by surpassing The End of Oak Street, Coyote vs. Acme has outgrossed five of the eight movies that Warner Bros. has put out in domestic theaters this year.... [It's just $17.6 million behind Supergirl, and within $30 million of Mortal Kombat II and Wuthering Heights.] Their anticipated sci-fi sequel Dune: Part Three also seems guaranteed to land higher than 2026's Coyote vs. Acme on the chart (2021's Dune earned $108.9 million in domestic theaters, while Dune: Part Two earned $282.1 million). With its a small marketing budget of just $10 million, the movie seems to be relying on oddball marketing stunts like their AMA on Reddit's r/movies. And commemorating the spirit of the movie, Crayon-maker Crayola even released a special "Coyote Secret Plan" web page for children to print and color — and partnered with the film's stars for a video on the importance of creativity: Lana Condor: Crayola is all about encouraging kids and grown-ups to turn imagination into action. Will Forte: Which is exactly what Coyote does in Coyote versus Acme. He sees a problem and thinks, "Could this be solved with a rocket, a catapult, or a suspiciously affordable mail order anvil?" Lana Condor: Usually no. Will Forte: Usually very no. Read more of this story at Slashdot.

  • Pentagon Investigators Say Overreliance on Palantir AI Contributed to US Strike That Killed 123 Iranian Children
    by EditorDavid on 22/09/2026 at 1:04 pm

    Two U.S. missiles hit an elementary school in Iran, killing over 150 people including 123 children on the first day of the Iran War. But Gizmodo notes that a new Bloomberg investigation cites U.S. officials involved in an unreleased internal Pentagon review who blame "a cascade of preventable failures that included an overreliance on an AI tool built by Palantir." According to the officials who spoke to Bloomberg, some personnel inside U.S. Central Command leaned too hard on the AI inside the Maven Smart System, an AI-powered data integration and targeting platform developed by Palantir to accelerate intelligence analysis and decision-making. The Defense Department has reportedly made the software tool a cornerstone of military operations over the past year... Officials said some users expected Maven to flag stale records or contradictions in the intelligence assembled for potential targets, though it is not clear why they thought the system would do that. The Minab [elementary school] site, which was cataloged as an Islamic Revolutionary Guard Corps facility due to outdated data, was fed into Maven with other candidates and came out as a recommended day-one target. Target-list work that once took hours was condensed into minutes. A Palantir spokesperson told Bloomberg the company "is not responsible for the underlying data nor identifying intelligence deficiencies" and that there is no evidence its software was at fault. Two people familiar with Palantir's Pentagon contracts said the government keeps primary responsibility for the quality of the information that's fed into Maven. After the strike, Palantir added features that "re-review underlying intelligence to identify factors that would disqualify a target and flag inconsistencies and inaccuracies that human review may have missed," a person familiar with the work said. That new functionality is said to have already caught some anomalies... More than 1,000 Iranian targets were hit in the first 24 hours, and according to Bloomberg's sources, that pace compressed the time available for additional confirmations. Staffing on civilian harm mitigation teams across the U.S. Department of Defense had also fallen by roughly 90% over recent years, shrinking to fewer than 20 people overall. The U.S. Central Command's group shrank from 10 people to one. No member of those teams reviewed the Minab site before the missiles were up in the air. A separate inquiry by the United Nations' Independent International Fact-Finding Mission on Iran this week reached the conclusion that there were reasonable grounds to believe the United States committed the war crime of launching an indiscriminate attack.

  • Google Opens Preorders for Its $899 Gemini-Enhanced 'Googlebook' Laptops
    by EditorDavid on 22/09/2026 at 8:34 am

    Monday Google opened preorders for its "Googlebook" laptops, pricing them at $899. A Google's blog post added that "At launch, you can choose between Intel Core Ultra Series 3 and Snapdragon X Elite processors" (paired with NPUs to power AI features). "Devices will hit shelves on October 4 in the U.S. and on October 5 in Canada, the U.K., Ireland, France, Germany, and Australia," TechCrunch points out. But "the real pull for the new devices is that they'll prominently feature Gemini's latest capabilities in a new format: the laptop." Google is trying to offer a laptop with unique features like an AI-powered cursor, vibe-coded widgets, and support for AI-enhanced dictation. The latter is a feature called Rambler, which cleans up messy, rambling brain dumps into readable text. The move is a bet that AI, specifically Google's Gemini, could be enough of a draw to get people to buy a new laptop that bakes in AI instead of running them via desktop apps you install or access through the browser... On the Googlebook, Google is trying to reinvent the "point-and-click" experience of desktop computing to now include an AI element: The cursor serves as a conduit to Gemini. The company suggests various ways this could be used, like highlighting content on a web page for Gemini to work with, asking Gemini to see if an email you've hovered your cursor over is suspicious, or selecting images and then asking Gemini to visualize them together... What's more interesting about the Googlebook is how it's seemingly part of Google's longer-term plan to capture a large part of the K-12 market that currently relies on Chromebooks and push them toward the company's Gemini AI. There are somewhere around 50 million Chromebooks in schools, used by students and educators, Google has said. In May, the company told TechCrunch that its current Chromebooks would continue to be supported, though many would become eligible to transition to the new Googlebook experience in the future... Flagship devices in the new range are being built by Acer, ASUS, Dell, HP, and Lenovo, with materials like aluminum, magnesium alloy, and carbon fiber... Google says the device will offer up to 14 hours of battery life. Googlebooks will be decorated with an exterior Glowbar "which dances when you boot up, sweeps to show battery level, and supports other playful patterns," according to Google's blog post. "We're also opening Glowbar access to developers to build custom, interactive animations." After testing actual Googlebooks, The Verge's reviewer first acknowledges that "it might be just another Trojan horse for Gemini." Still, "The hardware is polished (since it's based on current laptops). The OS is familiar (if you've ever used a Chromebook). But most impressive, it integrates your Android phone with your PC so they feel more like one device. It's the culmination of a series of new ideas that blur the two devices together. "After my first look, I went from doubtful to excited by the prospect of Google pulling it all off..." The Asus was incredibly lightweight; the Lenovo has plenty of ports and an optional mouse with a matching Glowbar light; the Acer's convertible form factor allows some tablet-like use (and it's pretty affordable for a Panther Lake laptop). The HP had a great-looking screen and a latticeless keyboard I surprisingly didn't hate, and the Dell is basically a gold XPS 13 (which is excellent) but with a different chip... But everything really special about Googlebooks comes down to software... You can cast apps from an Android phone directly to a Googlebook, even without touching your phone. Googlebooks essentially have two app drawers: a G-logo start menu for installed Googlebook apps and a second one beside it that pulls up mobile apps from your phone. Click a phone app and you can fully use that app with the mouse and keyboard or the Googlebook's touchscreen. It's a bit like iPhone Mirroring on macOS, but the apps are individually extracted to the desktop OS instead of showing your whole phone interface. Googlebooks also have a nifty feature called Continue On where the icons of apps you're currently using on your phone appear in the bottom bar — allowing you to click it on the laptop and hand it off to the Googlebook. These app handoffs can transition to a native app or a web app, depending on how developers have programmed it... The other big way Googlebooks interact with an Android phone is Quick Access, allowing you to see and access all the files stored on your phone right in the desktop Files app... If you have an iPhone then you're limited to a Link to iOS app that just does some message syncing and replying... [W]hen it comes to mainline gaming, Nvidia's GeForce Now service is also coming to Googlebooks, and the first year is free with one of Google's new laptops. "It's not every day we get a new player in the desktop operating system and laptop spaces," the reviewer points out. "There seems to be a higher ceiling of potential with Googlebooks than there was with Chromebooks, along with some cool features, but Google has a lot to prove at higher prices than people are used to paying for its laptops."

  • Meta's New 'Personal AI Agent' Muse Beats ChatGPT in Downloads - and Get Blocked by Amazon
    by EditorDavid on 22/09/2026 at 4:04 am

    Meta's AI "personal agent" Muse overtook ChatGPT as the #1 iOS free app in the U.S. on Friday, reports CNBC — and it's still showing more downloads as of Monday night. Muse now has over 2.5 million downloads since its debut less than two weeks ago, according to analytics firm Sensor Tower... [Muse] is currently ahead of popular services like OpenAI's ChatGPT, Polymarket and Kashi... It's also ahead of rival AI apps like Anthropic's Claude and SpaceXAI's Grok AI, in addition to the Facebook-parent's own Meta AI app... Meta pitched the app as a way for consumers to manage and direct supercharged digital assistants that can perform a number of tasks across the web, like filling out electronic forms and organizing email inboxes... "I think up to this point most of the agentic use cases have not really been for normal people," Bernstein analyst Stacy Rasgon told CNBC in a "Squawk on the Street" interview on Monday. "Now you've got Meta's Muse and other agents out there that are starting to maybe get more potential for more broad-based adoption." The buzz around Meta was also reflected in the stock, which surged more than 11% on Monday. Amazon is already blocking Muse, reports GeekWire. Amazon first tried to get Meta to voluntarily exclude Amazon, but they were unsuccessful: The problem, Amazon says, is that it never agreed to any of it. Meta didn't tell Amazon that Muse would access its store, the agent doesn't identify itself when it browses, and it appears to capture and store customer credentials, which the company says could create privacy and security risks. As of Sunday night, people trying to use Muse to shop on Amazon were seeing the popup, "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed..." Amazon has spent the past year trying to keep outside agents off its site, suing Perplexity over its Comet browser and moving to block shopping agents from Google and OpenAI. [Amazon won a preliminary injunction against Perplexity in March, the article poitns out, "then lost it on Aug. 4, when the Ninth Circuit ruled that the user — not the AI company — was the one accessing Amazon's computers under federal anti-hacking law. The court denied Amazon's petition for rehearing on Sept. 10."] On Sunday night, Amazon said it is in direct conversation with Meta about the issue. Asked whether it would consider taking legal action, the company declined to comment. The business stakes are high for Amazon. In addition to operating its flagship e-commerce site, Amazon generated more than $68 billion in ad revenue last year — a business that depends on people browsing its pages and seeing sponsored products. Muse also appears to scrape account data, reports CNBC. But Shopify, however, "is working with Meta on Muse access. Shopify CEO Tobias Lütke announced Monday that the e-commerce site was partnering with Muse to allow agentic checkout in its online stores." Read more of this story at Slashdot.
