Elon Musk asked a judge to block OpenAI's attempt to transition from nonprofit to for-profit. It's not the first time he's feuded with CEO Sam Altman.

Elon Musk, the eccentric but undeniably influential CEO of Tesla and SpaceX, has recently found himself at odds with some influential figures in the financial and tech space, notably Sam Altman of OpenAI and Nicolai Tangen of Norway’s sovereign wealth fund.

OpenAI’s CEO has stolen Musk’s thunder and it’s a lesson for every leader. Sam Altman and Elon Musk aren’t friends. They used to be colleagues back when the two were co-founders of OpenAI, and they seemingly shared the belief that artificial intelligence could be a huge net benefit for society.
