The longstanding feud between the OpenAI cofounders reignited over the weekend when the world’s richest man chimed in about Apple’s lawsuit against OpenAI.

Musk pounced on the Apple news to lambast Altman. Altman shot back in a reply on X Saturday in which he claimed Musk is “the one sellling public market investors on short-term space datacenters.”
