The world’s richest man, Elon Musk, and the CEO who heads the world's most popular AI company, Sam Altman, are once again at odds.

"I feel for the guy," Sam Altman told Bloomberg TV at the AI Action Summit in Paris. "I don’t think he’s a happy person."

Last March, Musk filed a lawsuit claiming OpenAI, a global leader in artificial intelligence innovation which has developed the ChatGPT chatbot, DALL-E image generator and other advanced AI-driven tools, breached promises made in its founding documents and prioritizes profit motive over serving the public good.
