Asked what most worried him about AI’s future, Altman replied: “One that I don’t think gets much attention is how are we going to avoid cognitive atrophy?”

His framing was less doom than discipline. “How are we going to use these tools and make sure that we are stretching our brains more and more and continuing to understand the stuff that really matters?” he asked, casting the danger as one of laziness rather than apocalypse.
