CEO of Open AI Sam Altman is facing allegations of sexual abuse by his sister, Ann Altman, in a lawsuit filed in Missouri. Altman and his family strongly deny the allegations, calling them 'utterly untrue' and stating that Ann has made similar accusations in the past. The lawsuit comes as OpenAI faces other high-profile challenges, including a lawsuit from Tesla CEO Elon Musk over a breach of contract. Legal proceedings are expected to take place as both sides present their cases in court.
