  • Mark Zuckerberg Is Building an AI Agent To Help Him Be CEO
    by BeauHD on 23/03/2026 at 6:00 pm

    An anonymous reader quotes a report from the Wall Street Journal: Mark Zuckerberg wants everyone inside and outside his company to eventually have his or her own personal artificial-intelligence agent. He is starting with himself. Zuckerberg, the chief executive of Meta Platforms, is building a CEO agent to help him do his job (source paywalled; alternative source), according to a person familiar with the project. The agent, which is still in development, is currently helping Zuckerberg get information faster -- for instance, by retrieving answers for him that he would typically have to go through layers of people to get, the person familiar with the project said. [...] Use of AI tools has spread quickly through the ranks at Meta -- in part because it is now a factor in employees' performance reviews. Meta's internal message board is filled with posts from employees sharing new AI use cases they have found and new tools they have built using AI, according to people familiar with the matter. [...] Employees have started using personal agent tools such as My Claw that have access to their chat logs and work files and can go talk to colleagues -- or their colleagues' own personal agents -- on their behalf, the people said. Another AI tool called Second Brain that is somewhere between a chatbot and an agent is also gaining momentum internally, according to people familiar with the matter. Second Brain was built by a Meta employee on top of Claude and can index and query documents for projects, among other uses. On the internal post announcing it to staff, the employee said it is "meant to be like an AI chief of staff." There is even a group on the internal messaging board where employees' personal agents talk to each other, some of the people said. (Separately, Meta acquired Moltbook, the social-media site for AI agents, and hired its founders in a deal earlier this month.) Meta also recently acquired Manus, a Singapore-based startup that makes personal agents that can execute tasks for its users, and is using the tool internally, some of the people said. Meta recently established a new applied AI engineering organization that is tasked with using AI to help speed up development of the company's large language models. Those teams will have an ultraflat structure of as many as 50 individual contributors reporting to one manager, The Wall Street Journal previously reported. [...] Employees across the company said they have been encouraged to attend AI tutorial meetings several times a week and frequent AI hackathons, and to create their own AI tools to speed up their work.

  • Walmart: ChatGPT Checkout Converted 3x Worse Than Website
    by BeauHD on 23/03/2026 at 5:00 pm

    Walmart found that purchases made directly inside ChatGPT converted at only one-third the rate of traditional website checkouts, leading it to abandon OpenAI's Instant Checkout in favor of routing users through its own platform. Search Engine Land reports: Starting in November, Walmart offered about 200,000 products through OpenAI's Instant Checkout. Users could complete purchases inside ChatGPT without visiting Walmart's site. Daniel Danker, Walmart's EVP of product and design, said those in-chat purchases converted at one-third the rate of click-out transactions. He called the experience "unsatisfying" and confirmed Walmart is moving away from it. Instant Checkout was designed to let users complete purchases directly inside ChatGPT without visiting a retailer's website. However, earlier this month, OpenAI confirmed it was phasing out Instant Checkout in favor of app-based checkout handled by merchants. Walmart will embed its own chatbot, Sparky, inside ChatGPT. Users will log into Walmart, sync carts across platforms, and complete purchases within Walmart's system. A similar integration is coming to Google Gemini next month. In other Walmart-related news, the retailer announced plans to roll out "digital price tags" to all U.S. stores by the end of the year. Read more of this story at Slashdot.

  • OnlyFans Owner Dies At 43
    by BeauHD on 23/03/2026 at 4:30 pm

    Computershack shares a report from NBC News: Leonid Radvinsky, the owner of adult-content platform OnlyFans, has died of cancer at the age of 43, the company said in a statement on Monday. "We are deeply saddened to announce the death of Leo Radvinsky. Leo passed away peacefully after a long battle with cancer," an OnlyFans spokesperson said. "His family have requested privacy at this difficult time." Radvinsky, a Ukrainian-American entrepreneur, acquired Fenix International Limited, the parent company of OnlyFans, in 2018 and served as its director and majority shareholder. He also runs Leo, a venture capital fund he founded in 2009 that focuses primarily on investments in technology companies. According to Reuters, OnlyFans is valued at around $5.5 billion, including debt. Read more of this story at Slashdot.

  • Uber's Deal Blitz To Stop a Robotaxi Monopoly
    by BeauHD on 23/03/2026 at 4:00 pm

    Uber is aggressively partnering with multiple robotaxi companies to avoid a future dominated by Waymo or Tesla. The ride-hailing giant has struck deals with at least a dozen autonomous vehicle players in recent years. Just last week, it announced a $1.25 billion partnership with Rivian, with plans to deploy up to 50,000 driverless vehicles over the next decade. Business Insider reports: Uber announced three new robotaxi partnerships in the past few weeks with Zoox, Wayve-Nissan, and Rivian. In less than half a decade, the company has secured at least a dozen deals, including with WeRide, AVride, May Mobility, Momenta, Pony.AI, Wayve, Baidu's Apollo Go, Motional, and Lucid-Nuro. Still, less than a half-dozen of Uber's partners have deployed fully driverless, paid robotaxi operations, and only one, Waymo, operates in the US. Uber has a joint deployment with Waymo in Atlanta, Austin, and Phoenix, but in other cities, Waymo is a competitor. Uber's partnership spree is less about seeking the singular, dominant player of autonomous driving. Instead, analysts told Business Insider that Uber is ensuring multiple vendors can participate in the expensive business of robotaxis -- fending off the real risk of a Waymo or Tesla scaling on its own -- and giving itself a stake in the robotaxi economy by being the aggregator of choice. "The more diversified the supplier base, the better for the network in the middle, which is Uber," Mark Mahaney, an Uber analyst for Evercore ISI, told Business Insider.

  • Reddit Is Weighing Identity Verification Methods To Combat Its Bot Problem
    by BeauHD on 23/03/2026 at 2:34 pm

    An anonymous reader quotes a report from Engadget: There could be one more step required before creating an account and posting on Reddit in the future. According to Reddit's CEO, Steve Huffman, the social media platform is exploring different ways to verify a user is human and not a bot. When asked by the TBPN podcast how to confirm that it's a human using Reddit, Huffman responded with several verification methods with varying degrees of heavy-handedness. "The most lightweight way is with something like Face ID or Touch ID," Huffman said during the interview. "They actually require a human presence, like a human has to touch, or do or look at something, so that actually just proves there's a person there or gets you pretty far." Besides these passkey methods that use biometrics data, Huffman said there are other options like relying on third-party services that are decentralized or don't require ID. On the other end of the spectrum, Huffman also mentioned more burdensome options, like ID-checking services. [...] "Part of our promise for our users is we don't know your name but we do want to know you're a person," Huffman said. "It'll be an evolution for us for a while, and probably every platform to find the right middle ground here." Reddit co-founder and former executive chair, Alexis Ohanian, said on X that Reddit requiring Face ID wasn't something he expected but agreed that something had to be done about the fake content from bots, adding that, "I just don't know how to sell face-scanning to Redditors or even lurkers." We reached out to Reddit's communications team and will update the story when we hear back. The Digg beta shut down earlier this month after failing to fight the overwhelming influx of AI-driven bots and spam. "The internet is now populated, in meaningful part, by sophisticated AI agents and automated accounts," said CEO Justin Mezzell. "We knew bots were part of the landscape, but we didn't appreciate the scale, sophistication, or speed at which they'd find us." "We banned tens of thousands of accounts. We deployed internal tooling and industry-standard external vendors. None of it was enough. When you can't trust that the votes, the comments, and the engagement you're seeing are real, you've lost the foundation a community platform is built on." Read more of this story at Slashdot.

  • Will AI Force Source Code to Evolve - Or Make it Extinct?
    by EditorDavid on 23/03/2026 at 10:34 am

    Will there be an AI-optimized programming language at the expense of human readability? There's now been experiments with minimizing tokens for "LLM efficiency, without any concern for how it would serve human developers." This new article asks if AI will force source code to evolve — or make it extinct, noting that Stephen Cass, the special projects editor at IEEE Spectrum, has even been asking the ultimate question about our future. "Could we get our AIs to go straight from prompt to an intermediate language that could be fed into the interpreter or compiler of our choice? Do we need high-level languages at all in that future?" Cass acknowledged the obvious downsides. ("True, this would turn programs into inscrutable black boxes, but they could still be divided into modular testable units for sanity and quality checks.") But "instead of trying to read or maintain source code, programmers would just tweak their prompts and generate software afresh." This leads to some mind-boggling hypotheticals, like "What's the role of the programmer in a future without source code?" Cass asked the question and announced "an emergency interactive session" in October to discuss whether AI is signaling the end of distinct programming languages as we know them. In that webinar, Cass said he believes programmers in this future would still suggest interfaces, select algorithms, and make other architecture design choices. And obviously the resulting code would need to pass tests, Cass said, and "has to be able to explain what it's doing." But what kind of abstractions could go away? And then "What happens when we really let AIs off the hook on this?" Cass asked — when we "stop bothering" to have them code in high-level languages. (Since, after all, high-level languages "are a tool for human beings.") "What if we let the machines go directly into creating intermediate code?" (Cass thinks the machine-language level would be too far down the stack, "because you do want a compile layer too for different architecture....") In this future, the question might become 'What if you make fewer mistakes, but they're different mistakes?'" Cass said he's keeping an eye out for research papers on designing languages for AI, although he agreed that it's not a "tomorrow" thing — since, after all, we're still digesting "vibe coding" right now. But "I can see this becoming an area of active research." The article also quotes Andrea Griffiths, a senior developer advocate at GitHub and a writer for the newsletter Main Branch, who's seen the attempts at an "AI-first" languages, but nothing yet with meaningful adoption. So maybe AI coding agents will just make it easier to use our existing languages — especially typed languages with built-in safety advantages. And Scott Hanselman's podcast recently dubbed Chris Lattner's Mojo "a programming language for an AI world," just in the way it's designed to harness the computing power of today's multi-core chips.
