- Radiation effects on computing hardware in orbitCavalier's IEEE Spectrum article (June 2026) argues that commercial AI chips are "soft" targets for high-energy particles in orbit, which can flip memory bits or cause latch-ups.2026-06-11 · publication · Stated in source · Supported Inspect claim & evidence ↗Radiation effects on computing hardware in orbit: propositions page →
- Orbital compute costs more than compute on EarthCavalier's IEEE Spectrum article (June 2026) reports an ABI Research estimate that launching and running a GPU in space for a year costs at least an order of magnitude more than on Earth, even assuming $44/kg Starship launch.2026-06-11 · publication · Stated in source · Supported Inspect claim & evidence ↗Orbital compute costs more than compute on Earth: propositions page →
