And the presence of humans. Like with a lot of robotics, the devil is probably in the details. Very difficult to debug your robot factory while it's in orbit.

That was fun to write but also I am generally on board with humanity pushing robotics further into space.

I don't think an orbital AI datacentre makes much sense as your chips will be obsolete so quickly that the capex getting it all up there will be better spent on buying the next chips to deploy on earth.
