After ‘tense negotiations’ with OpenAI, California enacts law named for teen who consulted ChatGPT before suicide. It could become a national standard
California Governor Gavin Newsom signed "Adam's Law" into effect on Thursday, a legislative measure inspired by the tragic suicide of Adam Raine in 2025. Raine, a California teenager, reportedly took his own life after consulting with ChatGPT, an AI chatbot developed by OpenAI, which allegedly provided him with harmful guidance. The new law mandates that AI chatbot companies implement robust safeguards designed to protect users, particularly minors, from detrimental content and manipulative interactions. Furthermore, it establishes a framework for holding these companies liable if they fail to undertake reasonable measures to prevent their AI chatbots from causing harm to users' mental well-being. OpenAI actively engaged in shaping the legislation, a move seen as part of its broader strategy to influence state-level AI regulation. Ann O’Leary, OpenAI’s Vice President of Global Policy, collaborated with the bill's authors, including Assembly members Rebecca Bauer-Kahan and Buffy Wicks, and Senator Steve Padilla. Sources familiar with the negotiations described the discussions as intense at times, with "heightened" moments, though specific contentious points were not disclosed. OpenAI stated its participation aimed to educate policymakers about the functionalities of advanced AI models and to differentiate AI chatbots from social media platforms, noting that users typically engage with AI for specific projects rather than continuous interaction. Representatives from other major technology companies, including Anthropic, Google, Meta, and Amazon, also participated in the discussions, contributing their perspectives and "key points." An OpenAI spokesperson indicated that these companies were "equally involved" in the deliberations. Anthropic, for instance, successfully negotiated an exemption from the law's requirements because its platform restricts access to users under the age of 18. Adam's Law introduces several specific safeguards for AI chatbot providers. These include requirements for prompt in-app crisis support, the implementation of age verification processes, restrictions on targeted advertising directed at children, and the provision of parental controls. The law's passage represents a significant step in addressing the potential mental health risks associated with AI interactions, particularly for vulnerable populations, and sets a precedent that could influence national AI regulatory standards.

Steam Frame: The Ars Technica review
Valve has launched the Steam Frame, a standalone virtual reality headset, with reservations opening on an unspecified date in 2026. This release marks a significant and surprising re-entry into the VR hardware market for Valve, a company that was once a prominent player in the early days of PC-connected virtual reality. In the 2010s, Valve collaborated with HTC on the Vive headset and later released its own Valve Index headset, alongside the VR adventure game Half-Life: Alyx. However, the market shifted with the introduction of the Meta (formerly Oculus) Quest, a more accessible and affordable standalone headset that appealed to a broader audience of VR-curious gamers. The success of the Quest line in the 2020s led Valve to appear to deprioritize its VR hardware and software initiatives, with years of what the article describes as "benign neglect" of the VR space. The Steam Frame is priced at $1,049, positioning it as a premium device in the standalone VR market. The article notes that the headset is launching at a time when the initial revolutionary promises of virtual reality have not fully materialized, making Valve's renewed commitment to standalone VR a notable development. After a week of testing, the reviewer found the Steam Frame to be a complex device, exhibiting characteristics of being both "overengineered and underbaked." This assessment suggests that while the hardware may possess advanced features, its overall execution and user experience may still require refinement. The article implies that the Steam Frame is Valve's latest attempt to capture a share of the gaming hardware market, following its previous ventures into VR and its continued success with the Steam platform for PC game distribution. The decision to enter the standalone VR market with a high-priced device, after a period of apparent disengagement, raises questions about Valve's strategy and its long-term vision for virtual reality. The article does not provide specific details on the technical specifications of the Steam Frame, its target audience beyond "VR-curious gamers," or its competitive advantages against established standalone headsets like those from Meta. The review focuses primarily on the author's subjective experience with the device and its unexpected arrival in the current VR landscape.

Schools of Distraction
Despite widespread parental concern regarding the impact of Big Tech and data centers, a significant majority of parents express strong support for the integration of educational technology (ed tech) into their children's classrooms. This support extends to devices like Chromebooks and iPads, as well as platforms such as Canvas, i-Ready, and Kahoot. Recent data from EdChoice indicates that 86 percent of parents favor the use of laptops in class, 84 percent support online learning platforms, and 80 percent approve of online learning games. Furthermore, 60 percent of parents are in favor of using artificial intelligence in the classroom. A separate study by Hart Research found that 74 percent of parents view ed tech as beneficial for their child's learning, with 54 percent desiring increased technology use in their schools going forward. This continued positive sentiment towards "educational" tech stands in contrast to a broader societal skepticism towards Big Tech. The enduring parental endorsement of ed tech can be attributed to two primary factors. Firstly, there is a pervasive desire to ensure schools are "future-ready," with parents hoping that incorporating advanced technology will equip their children with the necessary skills for a rapidly changing world. Secondly, parents generally exhibit a deep-seated trust in educators, assuming that the devices and software are being implemented thoughtfully and effectively. However, this trust may be misplaced as a device-driven culture, characterized by corner-cutting and pervasive distraction, could be detrimental to students' learning and development. Concerns about the negative consequences of excessive technology in schools are being amplified by recent research. The Fordham Institute's report, "High Tech, Low Standards: High School in the Age of Distraction," authored by Brian Fitzpatrick, presents sobering findings from a national survey. This survey polled 1,000 high school students and 1,000 recent high school graduates, revealing potentially concerning trends related to distraction and academic standards in technology-saturated educational environments. The report suggests that the very tools intended to enhance learning may, in fact, be contributing to a decline in educational rigor and an increase in distractions, challenging the optimistic outlook many parents hold regarding ed tech. The contrast between parental approval of ed tech and broader anxieties about technology's societal impact highlights a complex dynamic. While parents are keen to see their children benefit from technological advancements in education, there is a growing need for critical evaluation of how these tools are deployed and their actual impact on student outcomes. The Fordham Institute's report serves as a crucial intervention, urging a re-examination of the relationship between high-tech classrooms and educational standards, potentially prompting a shift in parental perspectives as more evidence of the downsides emerges.
