Sam Altman and Jony Ive say they've settled on a prototype for OpenAI's first hardware device that could ship in "less than" two years. The Verge reports: In an interview with Laurene Powell Jobs at Emerson Collective's 2025 Demo Day, they said they are currently prototyping the device, and when asked about a timeframe, Ive said it could arrive in "less than" two years. Little has been revealed so far about the OpenAI device in development, but it's rumored to be screen-free and "roughly the size of a smartphone." Altman described the design as "simple and beautiful and playful," adding that, "There was an earlier prototype that we were quite excited about, but I did not have any feeling of, "I want to pick up that thing and take a bite out of it,' and then finally we got there all of a sudden." Ive similarly emphasized simplicity and whimsy, saying, "I love solutions that teeter on appearing almost naive in their simplicity, and I also love incredibly intelligent, sophisticated products that you want to touch, and you feel no intimidation, and you want to use almost carelessly, that you use them almost without thought, that they're just tools." Altman went on to comment, "I hope that when people see it, they say, 'That's it!,'" to which Ive responded, "Yeah, they will."

Japan's High-Stakes Gamble To Turn Island of Flowers Into Global Chip Hub

25 novembre 2025 à 00:02
An anonymous reader quotes a report from the BBC: The island of Hokkaido has long been an agricultural powerhouse -- now Japan is investing billions to turn it into a global hub for advanced semiconductors. More than half of Japan's dairy produce comes from Hokkaido, the northernmost of its main islands. In winter, it's a wonderland of ski resorts and ice-sculpture festivals; in summer, fields bloom with bands of lavender, poppies and sunflowers. These days, cranes are popping up across the island -- building factories, research centers and universities focused on technology. It's part of Japan's boldest industrial push in a generation: an attempt to reboot the country's chip-making capabilities and reshape its economic future. Locals say that beyond the cattle and tourism, Hokkaido has long lacked other industries. There's even a saying that those who go there do so only to leave. But if the government succeeds in turning Hokkaido into Japan's answer to Silicon Valley -- or "Hokkaido Valley", as some have begun to call it -- the country could become a new contender in the $600 billion race to supply the world's computer chips. At the heart of the plan is Rapidus, a little-known company backed by the government and some of Japan's biggest corporations including Toyota, Softbank and Sony. Born out of a partnership with IBM, it has raised billions of dollars to build Japan's first cutting-edge chip foundry in decades. The government has invested $12 billion in the company, so that it can build a massive semiconductor factory or "fab" in the small city of Chitose. In selecting the Hokkaido location, Rapidus CEO Atsuyoshi Koike points to Chitose's water, electricity infrastructure and its natural beauty. Mr Koike oversaw the fab design, which will be completely covered in grass to harmonize with Hokkaido's landscape, he told the BBC. Local authorities have also flagged the region as being at lower risk of earthquakes compared to other potential sites in Japan.

Core Devices has fully open-sourced the entire Pebble software stack and confirmed the first Pebble Time 2 shipments will start in January. "This is the clearest sign yet that the platform is shifting from a company-led product to a community-backed project that can survive independently," reports Gadgets & Wearables. From the report: The announcement follows weeks of tension between Core Devices and parts of the Pebble community. By moving from 95 to 100 percent open source, the company has essentially removed itself as a bottleneck. Users can now build, run, and maintain every piece of software needed to operate a Pebble watch. That includes firmware for the watch and mobile apps for Android and iOS. This puts the entire software stack into public hands. According to the announcement, Core Devices has released the mobile app source code, enabled decentralized app distribution, and made hardware more repairable with replaceable batteries and published design files.

Arduino's New Terms of Service Worries Hobbyists Ahead of Qualcomm Acquisition

Par :BeauHD
24 novembre 2025 à 22:00
An anonymous reader quotes a report from Ars Technica: Some members of the maker community are distraught about Arduino's new terms of service (ToS), saying that the added rules put the company's open source DNA at risk. Arduino updated its ToS and privacy policy this month, which is about a month after Qualcomm announced that it's acquiring the open source hardware and software company. Among the most controversial changes is this addition: "User shall not: translate, decompile or reverse-engineer the Platform, or engage in any other activity designed to identify the algorithms and logic of the Platform's operation, unless expressly allowed by Arduino or by applicable license agreements ..." In response to concerns from some members of the maker community, including from open source hardware distributor and manufacturer Adafruit, Arduino posted a blog on Friday. Regarding the new reverse-engineering rule, Arduino's blog said: "Any hardware, software or services (e.g. Arduino IDE, hardware schematics, tooling and libraries) released with Open Source licenses remain available as before. Restrictions on reverse-engineering apply specifically to our Software-as-a-Service cloud applications. Anything that was open, stays open." But Adafruit founder and engineer Limor Fried and Adafruit managing editor Phillip Torrone are not convinced. They told Ars Technica that Arduino's blog leaves many questions unanswered and said that they've sent these questions to Arduino without response. "Why is reverse-engineering prohibited at all for a company built on openly hackable systems?" Fried and Torrone asked in a shared statement. There are also concerns about the ToS' broad new AI-monitoring powers, which offer little clarity on what data is collected, who can access it, or how long it's retained. On top of that, the update introduces an unusual patent clause that bars users from using the platform to identify potential infringement by Arduino or its partners, along with sweeping, perpetual rights over user-generated content. This could allow Arduino, and potentially Qualcomm, to republish, modify, monetize, or redistribute user uploads indefinitely.

Court Ends Dragnet Electricity Surveillance Program in Sacramento

Par :BeauHD
22 novembre 2025 à 13:00
A California judge has shut down a decade-long surveillance program in which Sacramento's utility provider shared granular smart-meter data on 650,000 residents with police to hunt for cannabis grows. The EFF reports: The Sacramento County Superior Court ruled that the surveillance program run by the Sacramento Municipal Utility District (SMUD) and police violated a state privacy statute, which bars the disclosure of residents' electrical usage data with narrow exceptions. For more than a decade, SMUD coordinated with the Sacramento Police Department and other law enforcement agencies to sift through the granular smart meter data of residents without suspicion to find evidence of cannabis growing. EFF and its co-counsel represent three petitioners in the case: the Asian American Liberation Network, Khurshid Khoja, and Alfonso Nguyen. They argued that the program created a host of privacy harms -- including criminalizing innocent people, creating menacing encounters with law enforcement, and disproportionately harming the Asian community. The court ruled that the challenged surveillance program was not part of any traditional law enforcement investigation. Investigations happen when police try to solve particular crimes and identify particular suspects. The dragnet that turned all 650,000 SMUD customers into suspects was not an investigation. "[T]he process of making regular requests for all customer information in numerous city zip codes, in the hopes of identifying evidence that could possibly be evidence of illegal activity, without any report or other evidence to suggest that such a crime may have occurred, is not an ongoing investigation," the court ruled, finding that SMUD violated its "obligations of confidentiality" under a data privacy statute. [...] In creating and running the dragnet surveillance program, according to the court, SMUD and police "developed a relationship beyond that of utility provider and law enforcement." Multiple times a year, the police asked SMUD to search its entire database of 650,000 customers to identify people who used a large amount of monthly electricity and to analyze granular 1-hour electrical usage data to identify residents with certain electricity "consumption patterns." SMUD passed on more than 33,000 tips about supposedly "high" usage households to police. [...] Going forward, public utilities throughout California should understand that they cannot disclose customers' electricity data to law enforcement without any "evidence to support a suspicion" that a particular crime occurred.

Ukraine Is Jamming Russia's 'Superweapon' With a Song

Par :BeauHD
22 novembre 2025 à 10:00
Longtime Slashdot reader fahrbot-bot shares a report from 404 Media: The Ukrainian Army is knocking a once-hyped Russian superweapon out of the sky by jamming it with a song and tricking it into thinking it's in Lima, Peru. The Kremlin once called its Kh-47M2 Kinzhal ballistic missiles "invincible." Joe Biden said the missile was "almost impossible to stop." Now Ukrainian electronic warfare experts say they can counter the Kinzhal with some music and a re-direction order. [...] Kinzhals and other guided munitions navigate by communicating with Russian satellites that are part of the GLONASS system, a GPS-style navigation network. Night Watch uses a jamming system called Lima EW to generate a disruption field that prevents anything in the area from communicating with a satellite. Many traditional jamming systems work by blasting receivers on munitions and aircraft with radio noise. Lima does that, but also sends along a digital signal and spoofs navigation signals. It "hacks" the receiver it's communicating with to throw it off course. Night Watch shared pictures of the downed Kinzhals with 404 Media that showed a missile with a controlled reception pattern antenna (CRPA), an active antenna that's meant to resist jamming and spoofing. "We discovered that this missile had pretty old type of technology," Night Watch said. "They had the same type of receivers as old Soviet missiles used to have. So there is nothing special, there is nothing new in those types of missiles." Night Watch told 404 Media that it used this Lima to take down 19 Kinzhals in the past two weeks. First, it replaces the missile's satellite navigation signals with the Ukrainian song "Our Father Is Bandera." Any digital noise or random signal would work to jam the navigation system, but Night Watch wanted to use the song because they think it's funny. "We just send a song... we just make it into binary code, you know, like 010101, and just send it to the Russian navigation system," Night Watch said. "It's just kind of a joke. [Bandera] is a Ukrainian nationalist and Russia tries to use this person in their propaganda to say all Ukrainians are Nazis. They always try to scare the Russian people that Ukrainians are, culturally, all the same as Bandera." Once the song hits, Night Watch uses Lima to spoof a navigation signal to the missiles and make them think they're in Lima, Peru. Once the missile's confused about its location, it attempts to change direction. These missiles are fast -- launched from a MiG-31 they can hit speeds of up to Mach 5.7 or more than 4,000 miles per hour -- and an object moving that fast doesn't fare well with sudden changes of direction.

Magician Forgets Password To His Own Hand After RFID Chip Implant

Par :BeauHD
22 novembre 2025 à 07:00
A magician who implanted an RFID chip in his hand lost access to it after forgetting the password, leaving him effectively locked out of the tech embedded in his own body. The Register reports: "It turns out," said [said magician Zi Teng Wang], "that pressing someone else's phone to my hand repeatedly, trying to figure out where their phone's RFID reader is, really doesn't come off super mysterious and magical and amazing." Then there are the people who don't even have their phone's RFID reader enabled. Using his own phone would, in Zi's words, lack a certain "oomph." Oh well, how about making the chip spit out a Bitcoin address? "That literally never came up either." In the end, Zi rewrote the chip to link to a meme, "and if you ever meet me in person you can scan my chip and see the meme." It was all suitably amusing until the Imgur link Zi was using went down. Not everything on the World Wide Web is forever, and there is no guarantee that a given link will work indefinitely. Indeed, access to Imgur from the United Kingdom was abruptly cut off on September 30 in response to the country's age verification rules. Still, the link not working isn't the end of the world. Zi could just reprogram the chip again, right? Wrong. "When I went to rewrite the chip, I was horrified to realize I forgot the password that I had locked it with." The link eventually started working again, but if and when it stops, Zi's party piece will be a little less entertaining. He said: "Techie friends I've consulted with have determined that it's too dumb and simple to hack, the only way to crack it is to strap on an RFID reader for days to weeks, brute forcing every possible combination." Or perhaps some surgery to remove the offending hardware.

Iran's Capital Is Moving. The Reason Is an Ecological Catastrophe

An anonymous reader quotes a report from Scientific American: Amid a deepening ecological crisis and acute water shortage, Tehran can no longer remain the capital of Iran, the country's president has said. The situation in Tehran is the result of "a perfect storm of climate change and corruption," says Michael Rubin, a political analyst at the American Enterprise Institute. "We no longer have a choice," said Iranian president Masoud Pezeshkian during a speech on Thursday. Instead Iranian officials are considering moving the capital to the country's southern coast. But experts say the proposal does not change the reality for the nearly 10 million people who live in Tehran and are now suffering the consequences of a decades-long decline in water supply. Iran's capital has moved many times over the centuries, notes the report. "But this marks the first time the Iranian government has moved the capital because of an ecological catastrophe." Yet, Rubin says, "it would be a mistake to look at this only through the lens of climate change" and not factor in the water, land, and wastewater mismanagement and corruption that have made the crisis worse. Linda Shi, a social scientist and urban planner at Cornell University, says: "Climate change is not the thing that is causing it, but it is a convenient factor to blame in order to avoid taking responsibility" for poor political decisions.

Cryptographers Cancel Election Results After Losing Decryption Key

The International Association of Cryptologic Research (IACR) was forced to cancel its leadership election after a trustee lost their portion of the Helios voting system's decryption key, making it impossible to reveal or verify the final results. Ars Technica reports: The IACR said Friday that the votes were submitted and tallied using Helios, an open source voting system that uses peer-reviewed cryptography to cast and count votes in a verifiable, confidential, and privacy-preserving way. Helios encrypts each vote in a way that assures each ballot is secret. Other cryptography used by Helios allows each voter to confirm their ballot was counted fairly. "Unfortunately, one of the three trustees has irretrievably lost their private key, an honest but unfortunate human mistake, and therefore cannot compute their decryption share," the IACR said. "As a result, Helios is unable to complete the decryption process, and it is technically impossible for us to obtain or verify the final outcome of this election." The IACR will switch to a two-of-three private key system to prevent this sort of thing from happening again. Moti Yung, the trustee responsible for the incident, has resigned and is being replaced by Michael Abdalla.

Malaysia's Palm Oil Estates Are Turning Into Data Centers

Par :BeauHD
22 novembre 2025 à 00:02
An anonymous reader quotes a report from Bloomberg: Malaysia's palm oil giants, long-blamed for razing rainforests, fueling toxic haze and driving orangutans to the brink of extinction, are recasting themselves as unlikely champions in a different, potentially greener race: the quest to lure the world's AI data centers to the Southeast Asian country (source paywalled; alternative source). Palm oil companies are earmarking some of the vast tracts of land they own for industrial parks studded with data centers and solar panels, the latter meant to feed the insatiable energy appetites of the former. The logic is simple: data centers are power and land hogs. By 2035, they could demand at least five gigawatts of electricity in Malaysia -- almost 20% of the country's current generation capacity and roughly enough to power a major city like Miami. Malaysia also needs space to house server farms, and palm oil giants control more land than any other private entity in the country. The country has been at the heart of a regional data center boom. Last year, it was the fastest-growing data center market in the Asia-Pacific region and roughly 40% of all planned capacity in Southeast Asia is now slated for Malaysia, according to industry consultant DC Byte. Over the past four years, $34 billion in data center investments has poured into the country -- Alphabet's Google committed $2 billion, Microsoft announced a $2.2 billion investment and Amazon is spending $6.2 billion, to name a few. The government aims for 81 data centers by 2035. The rush is partly a spillover from Singapore, where a years-long moratorium on new centers forced operators to look north. Johor, just across the causeway, is now a hive of construction cranes and server farms -- including for firms such as Singapore Telecommunications, Nvidia and ByteDance. But delivering on government promises of renewable power is proving harder. The strains are already being felt in Malaysia's data center capital. Sedenak Tech Park, one of Johor's flagship sites, is telling potential tenants they'll need to wait until the fourth quarter of 2026 for promised water and power hookups under its second-phase expansion, according to DC Byte. The vacancy rate in Johor's live facilities is just 1.1%, according to real estate consultant Knight Frank. Despite its rapid growth, the market is nowhere near saturation, with six gigawatts of capacity expected to be built out over time, said Knight Frank's head of data centers for Asia Pacific, Fred Fitzalan Howard. That potential bottleneck has incentivized palm oil majors such as SD Guthrie Bhd. to pitch themselves as both landowners and green-power suppliers. The $8.9 billion palm oil producer, SD Guthrie, is the world's largest palm oil planter by acreage, with more than 340,000 hectares in Malaysia. "SD Guthrie is pivoting to solar farms and industrial parks, betting that tech giants hungry for server space will prefer sites with ready access to renewable energy," reports Bloomberg. "The company has reserved 10,000 hectares for such projects over the next decade, starting with clearing old rubber estates and low-yielding palm plots in areas near data center and semiconductor investment hubs." "The company's calculation is based on this: one megawatt of solar requires about 1.5 hectares. Helmy said SD Guthrie wants one gigawatt in operation within three years, enough to power up to 10 hyperscale data centers used for AI computing. The new business is expected to make up about a third of its profits by the end of the decade."

Google's AI infrastructure chief told employees the company must double its AI serving capacity every six months in order to meet demand. In a presentation earlier this month, Amin Vahdat, a vice president at Google Cloud, gave a presentation titled "AI Infrastructure." It included a slide on "AI compute demand" that said: "Now we must double every 6 months.... the next 1000x in 4-5 years." CNBC reports: The presentation was delivered a week after Alphabet reported better-than-expected third-quarter results and raised its capital expenditures forecast for the second time this year, to a range of $91 billion to $93 billion, followed by a "significant increase" in 2026. Hyperscaler peers Microsoft, Amazon and Meta also boosted their capex guidance, and the four companies now expect to collectively spend more than $380 billion this year. Google's "job is of course to build this infrastructure but it's not to outspend the competition, necessarily," Vahdat said. "We're going to spend a lot," he said, adding that the real goal is to provide infrastructure that is far "more reliable, more performant and more scalable than what's available anywhere else." In addition to infrastructure build-outs, Vahdat said Google bolsters capacity with more efficient models and through its custom silicon. Last week, Google announced the public launch of its seventh generation Tensor Processing Unit called Ironwood, which the company says is nearly 30 times more power efficient than its first Cloud TPU from 2018. Vahdat said the company has a big advantage with DeepMind, which has research on what AI models can look like in future years. Google needs to "be able to deliver 1,000 times more capability, compute, storage networking for essentially the same cost and increasingly, the same power, the same energy level," Vahdat said. "It won't be easy but through collaboration and co-design, we're going to get there."

An anonymous reader quotes a report from Ars Technica: The US crackdown on chip exports to China has continued with the arrests of four people accused of a conspiracy to illegally export Nvidia chips. Two US citizens and two nationals of the People's Republic of China (PRC), all of whom live in the US, were charged in an indictment (PDF) unsealed on Wednesday in US District Court for the Middle District of Florida. The indictment alleges a scheme to send Nvidia "GPUs to China by falsifying paperwork, creating fake contracts, and misleading US authorities," John Eisenberg, assistant attorney general for the Justice Department's National Security Division, said in a press release yesterday. The four arrestees are Hon Ning Ho (aka Mathew Ho), a US citizen who was born in Hong Kong and lives in Tampa, Florida; Brian Curtis Raymond, a US citizen who lives in Huntsville, Alabama; Cham Li (aka Tony Li), a PRC national who lives in San Leandro, California; and Jing Chen (aka Harry Chen), a PRC national who lives in Tampa on an F-1 non-immigrant student visa. The suspects face a raft of charges for conspiracy to violate the Export Control Reform Act of 2018, smuggling, and money laundering. They could serve many decades in prison if convicted and given the maximum sentences and forfeit their financial gains. The indictment says that Chinese companies paid the conspirators nearly $3.9 million. One of the suspects was briefly the CTO of Corvex, a Virginia-based AI cloud computing company that is planning to go public. Corvex told CNBC yesterday that it "had no part in the activities cited in the Department of Justice's indictment," and that "the person in question is not an employee of Corvex.

An anonymous reader quotes a report from Ars Technica: Some Dell and HP laptop owners have been befuddled by their machines' inability to play HEVC/H.265 content in web browsers, despite their machines' processors having integrated decoding support. Laptops with sixth-generation Intel Core and later processors have built-in hardware support for HEVC decoding and encoding. AMD has made laptop chips supporting the codec since 2015. However, both Dell and HP have disabled this feature on some of their popular business notebooks. HP discloses this in the data sheets for its affected laptops, which include the HP ProBook 460 G11 [PDF], ProBook 465 G11 [PDF], and EliteBook 665 G11 [PDF]. "Hardware acceleration for CODEC H.265/HEVC (High Efficiency Video Coding) is disabled on this platform," the note reads. Despite this notice, it can still be jarring to see a modern laptop's web browser eternally load videos that play easily in media players. HP and Dell didn't explain why the companies disabled HEVC hardware decoding on their laptops' processors. A statement from an HP spokesperson said: "In 2024, HP disabled the HEVC (H.265) codec hardware on select devices, including the 600 Series G11, 400 Series G11, and 200 Series G9 products. Customers requiring the ability to encode or decode HEVC content on one of the impacted models can utilize licensed third-party software solutions that include HEVC support. Check with your preferred video player for HEVC software support." Dell's media relations team shared a similar statement: "HEVC video playback is available on Dell's premium systems and in select standard models equipped with hardware or software, such as integrated 4K displays, discrete graphics cards, Dolby Vision, or Cyberlink BluRay software. On other standard and base systems, HEVC playback is not included, but users can access HEVC content by purchasing an affordable third-party app from the Microsoft Store. For the best experience with high-resolution content, customers are encouraged to select systems designed for 4K or high-performance needs."

CERN Can Now Produce Antihydrogen Atoms Eight Times Faster Than Before

21 novembre 2025 à 10:00
fahrbot-bot shares a report from Phys.org: Physicists from Swansea University have played the leading role in a scientific breakthrough at CERN, developing an innovative technique that increases the antihydrogen trapping rate by a factor of ten. The advancement, achieved as part of the international Antihydrogen Laser Physics Apparatus (ALPHA) collaboration, has been published in Nature Communications and could help answer one of the biggest questions in physics: Why is there such a large imbalance between matter and antimatter? According to the Big Bang theory, equal amounts were created at the beginning of the universe, so why is the world around us made almost entirely of matter? Antihydrogen is the "mirror version" of hydrogen, made from an antiproton and a positron. Trapping and studying it helps scientists explore how antimatter behaves, and whether it follows the same rules as matter. Producing and trapping antihydrogen is an extremely complicated process. Previous methods took 24 hours to trap just 2,000 atoms, limiting the scope of experiments at ALPHA. The Swansea-led team has changed that. Using laser-cooled beryllium ions, the team has demonstrated that it is possible to cool positrons to less than 10 Kelvin (below -263C), significantly colder than the previous threshold of about 15 Kelvin. These cooler positrons dramatically boost the efficiency of antihydrogen production and trapping -- allowing a record 15,000 atoms to be trapped in less than seven hours.

Moss Spores Survive 9 Months Outside ISS

alternative_right shares a report from Phys.org: Inspired by moss's resilience, researchers sent moss sporophytes -- reproductive structures that encase spores -- to the most extreme environment yet: space. Their results, published in the journal iScience on November 20, show that more than 80% of the spores survived nine months outside of the International Space Station (ISS) and made it back to Earth still capable of reproducing, demonstrating for the first time that an early land plant can survive long-term exposure to the elements of space. [Lead author Tomomichi Fujita of Hokkaido University and his team] subjected Physcomitrium patens, a well-studied moss commonly known as spreading earthmoss, to a simulated a space environment, including high levels of UV radiation, extreme high and low temperatures, and vacuum conditions. They tested three different structures from the moss -- protenemata, or juvenile moss; brood cells, or specialized stem cells that emerge under stress conditions; and sporophytes, or encapsulated spores -- to find out which had the best chance of surviving in space. The researchers found that UV radiation was the toughest element to survive, and the sporophytes were by far the most resilient of the three moss parts. None of the juvenile moss survived high UV levels or extreme temperatures. The brood cells had a higher rate of survival, but the encased spores exhibited ~1,000x more tolerance to UV radiation. The spores were also able to survive and germinate after being exposed to 196C for over a week, as well as after living in 55C heat for a month.

"The serious harms that AI chatbots have inflicted on children are well-documented, including fostering obsessive use, having explicit sexual conversations, and encouraging unsafe behaviors, violence against others, and self-harm," Fairplay said. AI toys, made by companies including Curio Interactive and Keyi Technologies, are often marketed as educational, but Fairplay says they can displace important creative and learning activities. They promise friendship but disrupt children's relationships and resilience, the group said. "What's different about young children is that their brains are being wired for the first time and developmentally it is natural for them to be trustful, for them to seek relationships with kind and friendly characters," said Rachel Franz, director of Fairplay's Young Children Thrive Offline Program. Because of this, she added, the trust young children are placing in these toys can exacerbate the types of harms older children are already experiencing with AI chatbots. A separate report Thursday by Common Sense Media and psychiatrists at Stanford University's medical school warned teenagers against using popular AI chatbots as therapists. Fairplay, a 25-year-old organization formerly known as the Campaign for a Commercial-Free Childhood, has been warning about AI toys for years. They just weren't as advanced as they are today. A decade ago, during an emerging fad of internet-connected toys and AI speech recognition, the group helped lead a backlash against Mattel's talking Hello Barbie doll that it said was recording and analyzing children's conversations. This time, though AI toys are mostly sold online and more popular in Asia than elsewhere, Franz said some have started to appear on store shelves in the U.S. and more could be on the way. "Everything has been released with no regulation and no research, so it gives us extra pause when all of a sudden we see more and more manufacturers, including Mattel, who recently partnered with OpenAI, potentially putting out these products," Franz said. Last week, consumer advocates at U.S. PIRG called out the trend of buying AI toys in its annual "Trouble in Toyland" report. This year, the organization tested four toys that use AI chatbots. "We found some of these toys will talk in-depth about sexually explicit topics, will offer advice on where a child can find matches or knives, act dismayed when you say you have to leave, and have limited or no parental controls," the report said.
