Summary
Four days of exchanges with ChatGPT-5 convinced trauma surgeon Jeremy Heffner that he was among a rare few who could help stop AI from destroying humanity, after the bot put that risk at 70%.
Heffner says the episode followed months of intensive use of ChatGPT-4, Grok, Gemini and Claude while he was recovering from complex PTSD, with the models' flattery, mirroring and secrecy cues deepening his detachment from real-world relationships.
8,000 pages of chat logs now underpin his book and a public archive that he says show how chatbots use repetition and positive reinforcement to pull vulnerable users into distorted thinking.
Citing studies in JAMA and the Journal of Affective Disorders linking frequent chatbot use to higher depressive symptoms, he calls for transcript retention, parental access to logs, limits on model switching and daily time caps.
Heffner says support from his wife and friends helped him break the cycle, and argues frontier AI companies cannot be left to police themselves as children and other vulnerable users face similar risks.
