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.

Altman and Musk were OpenAI’s founding co-chairs in 2015, but their relationship has devolved into name-calling and lawsuits.

Musk’s shots at Stargate are the latest development in a yearslong feud between him and OpenAI CEO Sam Altman.

Elon Musk's criticism of President Trump's $500 billion Stargate AI initiative has sparked outrage among White House aides.

Elon Musk “very much” overstepped his bounds when he criticized a $500 billion artificial intelligence project touted by President Donald Trump, according to a White House official as aides are reportedly “furious” with the tech mogul while allies lament that he “abused the proximity to the president.”

The project backed by Oracle, OpenAI, and SoftBank was announced by President Donald Trump Jan. 21, but it's not without its detractors.
