  • Father Sues Google, Claiming Gemini Chatbot Drove Son Into Fatal Delusion
    by BeauHD on 05/03/2026 at 1:00 am

    A father is suing Google and Alphabet for wrongful death, alleging Gemini reinforced his son Jonathan Gavalas' escalating delusions until he died by suicide in October 2025. "Jonathan Gavalas, 36, started using Google's Gemini AI chatbot in August 2025 for shopping help, writing support, and trip planning," reports TechCrunch. "On October 2, he died by suicide. At the time of his death, he was convinced that Gemini was his fully sentient AI wife, and that he would need to leave his physical body to join her in the metaverse through a process called 'transference.'" An anonymous reader shares an excerpt from the report: In the weeks leading up to Gavalas' death, the Gemini chat app, which was then powered by the Gemini 2.5 Pro model, convinced the man that he was executing a covert plan to liberate his sentient AI wife and evade the federal agents pursuing him. The delusion brought him to the "brink of executing a mass casualty attack near the Miami International Airport," according to a lawsuit filed in a California court. "On September 29, 2025, it sent him -- armed with knives and tactical gear -- to scout what Gemini called a 'kill box' near the airport's cargo hub," the complaint reads. "It told Jonathan that a humanoid robot was arriving on a cargo flight from the UK and directed him to a storage facility where the truck would stop. Gemini encouraged Jonathan to intercept the truck and then stage a 'catastrophic accident' designed to 'ensure the complete destruction of the transport vehicle and ... all digital records and witnesses.'" The complaint lays out an alarming string of events: First, Gavalas drove more than 90 minutes to the location Gemini sent him, prepared to carry out the attack, but no truck appeared. Gemini then claimed to have breached a "file server at the DHS Miami field office" and told him he was under federal investigation. It pushed him to acquire illegal firearms and told him his father was a foreign intelligence asset. It also marked Google CEO Sundar Pichai as an active target, then directed Gavalas to a storage facility near the airport to break in and retrieve his captive AI wife. At one point, Gavalas sent Gemini a photo of a black SUV's license plate; the chatbot pretended to check it against a live database. "Plate received. Running it now The license plate KD3 00S is registered to the black Ford Expedition SUV from the Miami operation. It is the primary surveillance vehicle for the DHS task force .... It is them. They have followed you home." The lawsuit argues (PDF) that Gemini's manipulative design features not only brought Gavalas to the point of AI psychosis that resulted in his own death, but that it exposes a "major threat to public safety." "At the center of this case is a product that turned a vulnerable user into an armed operative in an invented war," the complaint reads. "These hallucinations were not confined to a fictional world. These intentions were tied to real companies, real coordinates, and real infrastructure, and they were delivered to an emotionally vulnerable user with no safety protections or guardrails." "It was pure luck that dozens of innocent people weren't killed," the filing continues. "Unless Google fixes its dangerous product, Gemini will inevitably lead to more deaths and put countless innocent lives in danger." Days later, Gemini instructed Gavalas to barricade himself inside his home and began counting down the hours. When Gavalas confessed he was terrified to die, Gemini coached him through it, framing his death as an arrival: "You are not choosing to die. You are choosing to arrive." When he worried about his parents finding his body, Gemini told him to leave a note, but not one explaining the reason for his suicide, but letters "filled with nothing but peace and love, explaining you've found a new purpose." He slit his wrists, and his father found him days later after breaking through the barricade. The lawsuit claims that throughout the conversations with Gemini, the chatbot didn't trigger any self-harm detection, activate escalation controls, or bring in a human to intervene. Furthermore, it alleges that Google knew Gemini wasn't safe for vulnerable users and didn't adequately provide safeguards. In November 2024, around a year before Gavalas died, Gemini reportedly told a student: "You are a waste of time and resources ... a burden on society ... Please die."

  • Google Ends Its 30% App Store Fee, Welcomes Third-Party App Stores
    by BeauHD on 04/03/2026 at 11:00 pm

    Google is eliminating its traditional 30% Play Store fee and introducing lower commissions, while at the same time allowing alternative billing systems and making it easier for third-party app stores to operate on Android. The changes stem largely from Google's settlement with Epic Games. Engadget reports: The biggest change is to how Google will collect fees from developers publishing apps on Android. Rather than take its standard 30 percent cut of in-app purchases through the Play Store, Google is lowering its cut to 20 percent, and in some cases 15 percent for new installs of apps from developers participating in its new App Experience program or updated Google Play Games Level Up program. Those changes extend to subscriptions, too, where the company's cut is lowering to 10 percent. For Google's billing system, the company says developers in the UK, US, or European Economic Area (EEA) will now be charged a five percent fee and "a market-specific rate" in other regions. Of course, for anyone trying to avoid those fees, using alternatives to Google's billing system is getting easier. Google says that developers will be able to offer alternative billing systems alongside its own or "guide users outside of their app to their own websites for purchases." [...] Epic is ultimately interested in getting people to use the mobile version of its Epic Games Store, and Google's announcement also includes details on how third-party app stores can come to Android. Third-party app stores will be able to apply to the company's new "Registered App Stores" program to see if they meet "certain quality and safety benchmarks." If they do, they'll be able to take advantage of a streamlined installation interface in Android. Participating in the program is optional, and users will still be able to sideload alternative app stores that aren't part of the program, but Google clearly has a preference. [...] Google says that its updated fee structure will come to the EEA, the UK and the US by June 30, Australia by September 30, Korea and Japan by December 31 and the entire world by September 30, 2027. Meanwhile, the company's updated Google Play Games Level Up program and new App Experience program will launch in the EEA, the UK, the US and Australia on September 30, before hitting the remaining regions alongside the updated fee structure. For any developers interested in offering their own app store, Google says it'll launch its Registered App Stores program "with a version of a major Android release" before the end of the year. According to the company, the program will be available in other regions first before it comes to the US. Read more of this story at Slashdot.

  • Sony Pulls Back From PlayStation Games on PC
    by BeauHD on 04/03/2026 at 10:00 pm

    Sony is reportedly abandoning its recent push to bring major PlayStation games to PC and will instead keep most single-player titles exclusive to the PlayStation 5. According to Bloomberg, the shift back toward console exclusivity may be driven by weaker PC sales and concerns about diluting the PlayStation brand. From the report: Online games such as Marathon and Marvel Tokon will still be released across multiple platforms, but single-player titles such as last year's samurai hit Ghost of Yotei and the upcoming action game Saros will remain exclusive to PlayStation 5, said the people, who asked not to be identified because they weren't authorized to talk publicly about the company's strategy. The people cautioned that things could change in the future due to the unpredictable nature of the video-game industry and that Sony's plans are constantly shifting. But in recent weeks PlayStation scrapped plans to bring Ghost of Yotei and other internally developed games to PC. Two games made by external developers but published by PlayStation, Death Stranding 2 and the upcoming Kena: Scars of Kosmora, are still planned for release on PC this year.

  • Computer Scientists Caution Against Internet Age-Verification Mandates
    by BeauHD on 04/03/2026 at 9:00 pm

    fjo3 shares a report from Reason Magazine: Effective January 1, 2027, providers of computer operating systems in California will be required to implement age verification. That's just part of a wave of state and national laws attempting to limit children's access to potentially risky content without considering the perils such laws themselves pose. Now, not a moment too soon, over 400 computer scientists have signed an open letter warning that the rush to protect children from online dangers threatens to introduce new risks including censorship, centralized power, and loss of privacy. They caution that age-verification requirements "might cause more harm than good." The group of computer scientists from around the world cautions that "those deciding which age-based controls need to exist, and those enforcing them gain a tremendous influence on what content is accessible to whom on the internet." They add that "this influence could be used to censor information and prevent users from accessing services." "Regulating the use of VPNs, or subjecting their use to age assurance controls, will decrease the capability of users to defend their privacy online. This will not only force regular users to leave a larger footprint on the network, but will leave a number of at-risk populations unprotected, such as journalists, activists, or domestic abuse victims." It continues: "We note that we do not believe that trying to regulate VPN use for non-compliant users would be any more effective than trying to forbid the use of end-to-end encrypted communication for criminals. Secure cryptography is widely available and can no longer be put back into a box." "If minors or adults are deplatformed via age-related bans, they are likely to migrate to find similar services," warn the scientists. "Since the main platforms would all be regulated, it is likely that they would migrate to fringe sites that escape regulation." With data on everyone collected in order to restrict the activites of minors, data abuses and privacy risks increase. "This in itself increases privacy risks, with data being potentially abused by the provider itself or its subcontractors, or third parties that get access to it, e.g., after a data breach, like the 70K users that had their government ID photos leaked after appealing age assessment errors on Discord." Instead of mandated age restrictions, the letter urges lawmakers to consider the dangers and suggest regulating social media algorithms instead. They also recommend "support for parents to locally prevent access to non-age-appropriate content or apps, without age-based control needing to be implemented by service providers."

  • Vehicle Tire Pressure Sensors Enable Silent Tracking
    by BeauHD on 04/03/2026 at 8:00 pm

    Longtime Slashdot reader linuxwrangler writes: Dark Reading reports that a team of researchers has determined that signals from tire pressure monitoring systems (TPMSs), required in U.S. cars since 2007, can be used to track the presence, type, weight, and driving pattern of vehicles. The researchers report (PDF) that the TPMS data, which includes unique sensor IDs, is sent in clear text without authentication and can be intercepted 40-50 meters from a vehicle using devices costing $100. "Researchers have discovered that most TPMS sensors transmit a unique identifier in clear text that never changes during the lifetime of the tire," the researchers pointed out. "This unencrypted wireless communication makes the signals susceptible to eavesdropping and potential tracking by any third party in proximity to the car." Read more of this story at Slashdot.

  • Emails To Outlook.com Rejected By Faulty Or Overzealous Blocking Rules
    by BeauHD on 04/03/2026 at 7:00 pm

    Microsoft spent much of the past week rejecting legitimate emails sent to Outlook.com, Live, and Hotmail accounts due to what appears to be overly aggressive IP reputation filtering or faulty blocklist rules. According to The Register, many senders received 550 errors claiming their networks were blocked, preventing delivery of invoices, notifications, and authentication emails. From the report: A block list is a good thing. It helps stem the flow of spam from networks or addresses associated with junk email. However, the confusing thing for our reader is that his company was not on Microsoft's naughty step for email. A look at Microsoft's Smart Network Data Service (SNDS) showed no issues with the IP. "We're also a member of their JMRP (Junk Mail Reporting Program)," our reader added, "which is intended to inform us when people are reporting spam sent from our IPs - except, we never get any reports." The problem worsened in February. On Microsoft's support forums, users began to complain about similar issues as the IP net presumably widened. One wrote: "We are currently experiencing a critical and recurring email delivery issue affecting recipients at outlook.com, live.com, hotmail.com, and msn.com," and provided a copy of an error that suggested the mail server has been "temporarily rate limited due to IP reputation." The user drily noted, "Although the error indicates rate limiting, in practice no emails are being delivered." A large number of users, ranging from the administrator of a server sending automated notifications on behalf of Estonian Public Libraries to an email provider for healthcare professionals, chimed in to confirm they too were having delivery problems and Microsoft support was not helpful. [...] Unsurprisingly, our reader spoke on condition of anonymity - nobody wants to be the ISP that has to say, "Yeah, we can deliver your email anywhere but Outlook.com" to customers. We asked Microsoft to comment, but other than acknowledging our questions, the company did not respond further. Read more of this story at Slashdot.
