The market decides that, not Elon. Do customers want to pay $X for compute in Iceland (or wherever), or do they want to pay $kX for compute in space?

What premium are customers willing to pay for compute in space? I would guess that the premium is actually negative because the quality of computation in space is worse than under the sweet embrace of Earth's atmosphere which provides a natural protection against radiation.

No premium, it's just a question of whether people can and are willing to build enough in those other places. Space is a bet that they can't. Also, I don't think bitflips are a huge deal in space for neural nets, we already build in randomness via temperature. A little more shouldn't make things noticeably worse. Higher energy particles could be a problem over time, but when I looked into it, it looked like the incidence of very damaging particles for a given area was surprisingly low.
