PendingElon Musk predicted space would be the most economically compelling place for AI by Feb 28, 2029. It hasn't happened yet, with 869 days left.
Fetched Oct 3 2026: SpaceX/Tesla are building Terafab and talking space-based compute, but terrestrial data centers remain the economically dominant place to put AI (Epoch AI Colossus 2 still ~946 MW IT in Memphis). No evidence space has become 'the most economically compelling place' for AI. Deadline Feb 2029. Status stays pending. Epoch AI Colossus 2 (updated Oct 2 2026, fetched Oct 3) — terrestrial Memphis cluster still the live AI compute site ↗
On the Dwarkesh Podcast published February 5, 2026, Musk said 'mark my words' that within 36 months — probably closer to 30 — the most economically compelling place to put AI will be space, as Earth's power-generation and cooling limits push large-scale compute into orbit where solar power is continuous. He argued it would then get 'ridiculously better' to be in space. The falsifiable test is whether, by roughly early 2029, orbit is genuinely the cheapest place to deploy AI compute at scale.
