I still don't understand the "data center in space" narrative. How are they going to solve the cooling issue?

Cooling a datacenter in space isn't really any harder than cooling a starlink in space, the ratio of solar panels to radiating area will have to be about the same. There is nothing uniquely heat-producing about GPUs, ultimately almost all energy collected by a satellite's solar panels ends up as heat in the satellite.

IMO the big problem is the lack of maintainability.

Sure, but cooling a starlink in space is a lot more difficult than cooling a starlink on earth would be. And unlike starlink which absolutely must be in space in order to function, data centers work just fine on the ground.

This. There's no scenario where it's cheaper to put them in space.
