Space GPUs delay deployment of the scarcest resource

Space data centers don't make sense this decade because they don't escape the binding constraint (chip supply, ~200 GW/yr by 2030) and add huge costs: testing then shipping unreliable GPUs (15% of Blackwells need RMA) to orbit could cost ~6 months of a 5-year useful life—the most valuable months—while inter-satellite networking requires expensive, unreliable space lasers instead of high-volume pluggable transceivers.
