Grok weighs in on space-based AI compute: thermodynamically viable, but Earth stays cheaper
johnseach · x · 2026-11-05
Sharing Grok's assessment of space-based AI compute: radiators make it thermodynamically viable and modest deployments practical. But at superintelligence-scale compute, it remains an ambitious engineering and economic bet rather than a clearly superior solution — attractive only if terrestrial constraints (power, land, water, permitting) bite and launch costs fall dramatically. For most workloads and timelines, optimized Earth-based systems remain simpler, cheaper, and more practical.
