In this episode of Galaxy Brain, Charlie Warzel explores the strange, unsettling relationships some people are having with AI chatbots, as well as what happens when those relationships go off the rails. His guest is Kashmir Hill, a technology reporter at The New York Times who has spent the past year documenting what is informally called ?AI psychosis.? These are long, intense conversations with systems such as ChatGPT that can spiral or trigger delusional beliefs, paranoia, and even self-harm. Hill walks through cases that range from the bizarre (one man?s supposed math breakthrough, a chatbot encouraging users to email her) to the tragic, including the story of 16-year-old Adam Raine, whose final messages were with ChatGPT before he died by suicide. 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.

In this episode of ?Galaxy Brain,? Charlie Warzel sits down with Eliot Higgins, founder of the open-source investigative collective Bellingcat, to examine how our public sphere slid from healthy debate into what Higgins calls ?disordered discourse.? Higgins is an early-internet native who taught himself geolocation during the Arab Spring and later built Bellingcat?s global community. He has spent the past decade exposing war crimes and online manipulation with publicly available data. Higgins has recently come up with a framework to help understand our information crisis: Democracies function only when we can verify truth, deliberate over what matters, and hold power to account. All three are faltering, he argues. In this conversation, Warzel and Higgins trace the incentives that broke the feed: how algorithms reward outrage, how ?bespoke realities? form, why counterpublics can devolve into virtual cults, and what ?simulated? accountability looks like in practice. They revisit Higgins?s path from early web forums to Bellingcat, look at the MAGA coalition as a patchwork of disordered counterpublics, and debate whether America is trapped in a simulated democracy. Higgins offers a clear diagnosis?and a plan for how we might begin to claw back a shared reality. Get more from your favorite Atlantic voices when you subscribe.

In this inaugural episode of Galaxy Brain, Charlie Warzel examines the state of the internet as it stands now in November 2025 with Hank Green, a true citizen of the internet?somebody who has made a living riding the algorithmic waves of the social web. Warzel and Green look back on a time when the internet felt small, more serendipitous, and inspiring, and try to tease apart what went wrong. Are people starting to leave TikTok? How exactly did the internet turn into a misery machine? What makes a great headline? Why is it easier now for some people to trust creators over institutions? Green helps make sense of the internet we live on and offers his reasons for why it might get worse before it gets better (but it could get better!). Sign up for the Galaxy Brain newsletter.
