Elon Musk weighed in on the row around artificial intelligence (AI) after a US lawsuit alleged that OpenAI’s ChatGPT made an already mentally unwell man commit a murder, then commit suicide.“This is diabolical. OpenAI’s ChatGPT convinced a guy to do a murder-suicide!” Musk wrote on X. The Tesla boss added: “To be safe, AI must be maximally truthful-seeking and not pander to delusions.”The family of an elderly woman killed in her Connecticut home last year has filed a lawsuit against OpenAI, alleging that conversations with ChatGPT helped fuel the delusions that led to a murder suicide.Suzanne Eberson Adams, 83, was killed in August at her home in Greenwich. Police say her son, Stein-Erik Soelberg, 56, murdered her before taking his own life.
