TL;DW:

Does It Make Sense To Put Data Centers In Space?

At some point in the future, yes.

Can They Really Cost Less To Operate?

In theory, yes.

Scott expresses concerns that current startups have not adequately addressed some of the practical challenges, such as cooling.

no one says space is a β€œfrozen” vacuum except movies.

Sorry, that embellishment (?) was probably mine; I guess I meant to say "really cold". And it is really cold, but it's also a very good insulator.

Actually, thinking about it, it really is freezing, isn't it? If you took some liquid water and just let it out into space, wouldn't it eventually freeze? It'd just take a really long time.

Matter not sunlit in space really is cold (and sunlit matter is baking hot, btw). It's just there is so little matter in space (vacuum and all) that getting rid of heat via conduction is virtually impossible, meaning it's insulated. So technically space is cold, also hot, and also damn well insulated.

Water not exposed to sunlight could get as low as - 260C (close to absolute zero) by radiating away all it's heat... eventually. Meanwhile water exposed to our sun in Earth orbit would be at around boiling temps, like 100-140C. Just check the Moon surface temperature readings.
