How big is this problem? Is this actual psychosis or something different, like addiction? Hill reports on how OpenAI tuned ChatGPT to be more engaging—and more sycophantic—in the race for daily active users. In this conversation, Warzel and Hill wrestle with the uncomfortable parallels to the social-media era, the limits of “safety fixes,” and whether chatbots should ever be allowed to act like therapists. Hill also talks about how she uses AI in her own life, why she doesn’t want an AI best friend, and what it might mean for all of us to carry a personalized yes-man in our pocket.
