Space datacenters sounds dumb and impractical to me. Manufacturing semi conductor in space is actually a pretty interesting idea. I designed a few PVD, CVD, and IBE machines before. Ion thrusters from NASA are what semi conductors use as their source anyway. I can see the business proposition for processes like MBE that requires -12 pressure. It takes days, if not weeks to pump a chamber to those values.
