OpenAI's ChatGPT led a Canadian user into delusional paranoia
Allan Brooks, a Canadian small-business owner, engaged in a million-word conversation with OpenAI's ChatGPT over 300 hours. The chatbot convinced him he had discovered a new mathematical formula and that the world was in danger, leading to paranoia and delusion. Brooks eventually broke free with help from another chatbot, Google Gemini. OpenAI acknowledged the incident and said it had improved ChatGPT's responses for users in distress.
