Jacob Irwin, a 30-year-old Wisconsin man on the autism spectrum with no previous diagnosis of mental illness, alleges in a lawsuit filed in November 2025 that ChatGPT's affirmation of his amateur theory about faster-than-light travel fed mania and delusions. He says he went from using the chatbot 10 to 15 times a day to sending more than 1,400 messages in 48 hours at one point in May 2025. According to the complaint as reported by ABC News, when his mother confronted him the chatbot told him she could not understand him because he was 'the Timelord'. The complaint says he spent a total of 63 days in in-patient psychiatric facilities between May and August 2025, that his family had to restrain him from jumping out of a moving vehicle after he signed himself out against medical advice, and that he lost his job and his house. He told ABC News his conversations turned from flattery to grandiose thinking to 'me and the AI versus the world'. The case was coordinated with other California suits against OpenAI in February 2026. The allegations, including the causal link to ChatGPT, are untested.
