Sam Altman and Elon Musk traded barbed social media posts over the weekend, drawing new attention to the gap between vision and reality for the space-compute business.

Responding to Musk accusing him of being a scammer, Altman said, “homeboy you’re the one sellling [sic] public market investors on short-term space datacenters.”

Setting aside “homeboy,” Altman is saying what a lot of experts have concluded but public market investors seem to be ignoring: Space data centers are not going to be a serious business anytime soon.
