It's the latest in a feud between the two billionaires that started on OpenAI’s board and is now testing Musk’s influence with the new president.

OpenAI CEO Sam Altman called Stargate, “the most important project for this era” and promised that all of the new investment his company was making would help cure diseases. Altman was actually prompted by Trump to talk about the medical advances that AI would supposedly figure out.
