The article makes a lot of points about cost viability, but says nothing about what happens at the end of life for space datacenters.

On Earth, the materials and equipment in the datacenter can be repurposed, recycled, or properly disposed of. In space, EOL'ed stuff either stays in orbit, burns in the atmosphere on reentry, or moved out of useful orbits.

I'm not sure I'm thrilled at the idea of more space junk in orbit or more aerosolized metals in the stratosphere.

The best thinking I've read on this topic is here:

(The entire post is well worth your time too.)

The most interesting argument I've heard is that in space there are no NIMBYs to protest or local (or state) politicians to extract donations. Yes, there aren't many slots for geostationary orbits, but in most other cases there's plenty of room.
