Taranis - Datacenters in space are a terrible, horrible, no good idea.

2025-11-30

My first reaction when I read about the plans of building datacenters in space was "wait, are we sure this is going to work? I don't think it's realistic".

The author knows more about the topic than I do (to be honest that's a low bar) but their opinion is the same.

I suppose this is just about possible if you really want to do it, but I think I've demonstrated above that it would firstly be extremely difficult to achieve, disproportionately costly in comparison with Earth-based datacenters, and offer mediocre performance at best.

If you still think this is worth doing, good luck, space is hard. Myself, I think it's a catastrophically bad idea, but you do you.
