A lot of very smart people are tying themselves in knots trying to explain why dissipating heat from a compute satellite is impossible. All they’ve really guaranteed is that they’ll never get a job at SpaceX. It used to be: “You can’t build an EV that performs as well as an ICE vehicle.” “You can’t build EV batteries at scale.” “You can’t solve autonomous driving with cameras and vision alone.” “You can’t land and reuse an orbital-class rocket.” “You can’t build an electric semi.” “You can’t manufacture cars at that scale.” Now it’s: “You can’t build a space-based AI compute satellite.” “You can’t scale terrestrial compute that fast.” “You can’t manufacture advanced AI chips at scale.” “You can’t build AI models that challenge the frontier labs.” “You can’t build a general-purpose humanoid robot that works at scale.” “You can’t get to Mars.”
