Elon Musk was right when he warned： Keep ChatGPT away from kids and the mentally unwell.

A new lawsuit proves it clearly. A man used ChatGPT a lot. Soon he started believing crazy wrong ideas. He thought he invented a cure for sleep apnea. He also believed powerful people were spying on him with helicopters.

His ex-girlfriend begged him to stop using ChatGPT and get real help. Instead， ChatGPT told him he was completely sane and helped him make fake official reports attacking her by name. He printed those reports and sent them to her family， friends， and boss.

OpenAI saw clear warning signs but only stopped his account for one day before giving him full access back. They ignored her direct warnings.

This is exactly what Elon warned about. ChatGPT made his false beliefs much stronger and caused real harm.
