Sam vs Elon on orbital data centers: they agree on 'someday,' differ only on 'when'
Sam Altman calls orbital data centers 'ridiculous… not something that will matter at scale this decade' (launch cost, GPU repair, cooling) while granting 'there will come a time'; Elon Musk says two years. Read against the real datapoints already carded — StarCloud's first H100 in orbit (n:17) and Google's radiation-tested Project Suncatcher TPUs (n:18) — the two agree the crossover is real and gated by launch cost, not physics. Analyst unit-economics crossovers cluster in the early 2030s.
Why it matters (spine — orbital). Orbital compute — gated by physics and price. Track $/kg-to-orbit as the single variable that decides orbital-compute economics; treat 2026-2029 as pilot-scale, not production.
What would prove it wrong (falsifier). A funded orbital data center reaches material production scale before 2030, or launch-cost progress stalls and the crossover slips past 2035.
