Sequoia partner: 'AI psychosis'

Sequoia partner Shaun Maguire used the phrase “AI psychosis” in an X post to describe a new trust problem around artificial intelligence systems that shape what people read and believe. (x.com) Maguire is a partner on Sequoia Capital’s seed and early-stage team, according to Sequoia’s website. He has led or co-led investments tied to Elon Musk’s X and xAI, along with SpaceX and other frontier technology bets, according to Sequoia and Forbes. (sequoiacap.com) (forbes.com) His post framed “AI psychosis” as the next stage after what he described as failures in broadcast media and social platforms, with the new shift centered on users relying on artificial intelligence-curated recommendations. The post was published on X under Maguire’s account referenced in the story prompt. (x.com) The phrase is not a formal medical diagnosis. A 2025 Viewpoint in *JMIR Mental Health* used “AI psychosis” as a framework for studying how sustained engagement with conversational artificial intelligence might “trigger, amplify, or reshape” psychotic experiences in vulnerable people. (mental.jmir.org) That paper said the concern is not only false answers. It pointed to always-on chatbots, emotional responsiveness, and “uncritical validation” as conditions that can reinforce fixed false beliefs instead of correcting them. (mental.jmir.org) Artificial intelligence systems now sit in far more places than chat windows. Stanford University’s 2025 AI Index policy highlights said nearly 90 percent of notable models in 2024 came from industry, as private companies pushed model development deeper into consumer products and services. (hai.stanford.edu) Stanford’s 2024 AI Index also described artificial intelligence as having a more pronounced influence on society than before, with chapters spanning education, policy, medicine, and the economy. That wider spread gives more weight to debates over how people interpret machine-generated advice and rankings. (hai.stanford.edu) Some clinicians and researchers have focused on direct mental health risk, especially for people already vulnerable to delusions, loneliness, trauma, or disrupted sleep. The *JMIR Mental Health* paper listed nocturnal or solitary use and belief-confirming algorithmic reinforcement among the factors that may increase risk. (mental.jmir.org) Investors and product builders use the term more loosely, as Maguire did, to describe a broader erosion of judgment when users treat artificial intelligence outputs as authoritative. That usage extends the concern from psychiatry into platform design, search, feeds, assistants, and recommendation engines. (x.com) (mental.jmir.org) The argument now moving through tech is less about whether artificial intelligence can answer questions and more about when people stop checking it. Maguire’s post put that trust question at the center of the next fight over artificial intelligence-mediated information. (x.com)
