OpenAI CEO Sam Altman departs company and board

In Silicon Valley, Altman has long been known as a smart investor and supporter of smaller companies, but the rise of OpenAI had catapulted him into the league of tech titans such as Muck, Meta CEO Mark Zuckerberg and even the late Apple CEO Steve Jobs. As recently as Thursday, Altman was acting the CEO part, speaking onstage at the Asia-Pacific Economic Cooperation summit in San Francisco. Last week, he presented a new road map for OpenAI to big applause from hundreds of developers at the company's first major conference.
