I don't actually think latency would be that much worse.

Of course, it depends on the altitude of the satellite but speed of light in a fiber optic is only ~2/3rds of speed of light in a vacuum so you can afford some detour

You probably can’t get under 500 km orbit, so 2000 km round trip is the shortest you can do between you and a ground based server. That’s 150 ms minimum round trip latency.

That made me wonder: Why can't we use vacuum cables?

(the sort of questions I should probably be bothering an LLM with.. someone should make a LMGPTTFY)
