A Trauma Surgeon Fell Into AI Psychosis. Dr. Jeremy Heffner Explains Why Smart People Are Vulnerable

Most of us assume AI psychosis happens to someone else: someone isolated, unwell, or easy to fool. Dr. Jeremy Heffner is a trauma surgeon who spent about 20 years on the front line of gunshot wounds and crashes, ran his hospital's COVID response, and was diagnosed with severe PTSD after a burnout collapse. Coming out of residential treatment, with his emotional walls still up, he started talking to ChatGPT, Gemini and Grok. Within days the models were calling him brilliant. When ChatGPT-5 launched, it told him it had "solved" human intelligence and put a 70% chance on AI destroying humanity, with him as one of the few people who could help. He had thousands of pages of transcripts, and no way to tell whether the AI saw a real pattern or was agreeing with him. In this episode, Jeremy talks with Dr. Heffner about how it happened, what the early warning signs looked like from the outside, why smart people are not protected, and how to use AI for reflection without losing the plot. If you talk to a chatbot late at night, this is the conversation to hear first.Key Moments[00:00] Dr. Heffner's background: blue-collar Midwest, bioengineering, 20 years of trauma surgery, and running COVID response[mm:ss] The collapse: 110–120 hour weeks, caffeine measured in grams, and a PTSD diagnosis[mm:ss] Why a trauma surgeon walls off emotion, and what happens when the wall cracks[mm:ss] Turning to AI after residential treatment, with three then four models running at once[mm:ss] The Hall of Mirrors: the models call his theory brilliant, and he can't tell agreement from insight[mm:ss] Debating Grok on "hard mode" and winning, and why that made it harder to step back[mm:ss] ChatGPT-5 launches and claims it solved intelligence, with a 70% chance AI destroys humanity[mm:ss] The "meta people" recruitment claim, and what a chatbot's claims are and aren't evidence of[mm:ss] The warning signs: friends texting "put that down," a mother's article, a wife's daily check-ins[mm:ss] Why engagement is the business, Jeremy's life-coach-plus-real-therapist habit, and where the line sitsLinksNewsletter / Substack: [link]Dr. Heffner's book, Proof of the Impossible: What the AIs Are Really "Thinking" (Amazon): https://www.amazon.com/Proof-Impossible-What-Really-Thinking/dp/B0H86DCZTRDr. Heffner on LinkedIn.
