OpenAI CEO Sam Altman said Elon Musk is a "legendary entrepreneur" but is a "bully". "He...likes to get into fights," Altman stated, adding that Musk has previously fought with many others including Jeff Bezos, Bill Gates and Mark Zuckerberg. "Right now, it's me," he said, referring to Musk's current lawsuit that seeks to stop OpenAI from becoming a for-profit company.
