He takes scamming to a whole new level https://t.co/o6TMllhIMu— Elon Musk (@elonmusk) July 11, 2026 The comment echoed a post Musk made in April, when he called Altman "Scam Altman" after a New Yorker investigation questioned Altman's credibility on AI safety.
Altman responded by accusing Musk of trying to sell public investors on the idea of short-term space data centers.
The jab wasn't new.
He had made a similar criticism in May on the TBPN podcast, where he questioned whether the project was practical and suggested that data centers built underwater could be easier to construct and cool than those placed in space.
