One thing that I haven’t seen represented as a risk in space based datacenters is the satellite reentry debris pollution. We are essentially allowing a constant rain of heavy metals, silicon, arsenic, and other nasty things if this idea goes to scale.

Even if all the technical issues can be worked out, which I doubt, the incentives are there to pump as many as possible up there. I don’t think we want to live with that raining down on us all.
