> In our downside scenario, orbital data centers won’t work or offer any advantage over terrestrial ones

Technologically, will they work? Shovel enough money at the problem and there's no reason they shouldn't. Rack up some GPUs in a shipping container, attach a couple of solar panels to the outside, zip-tie a Starlink to the door. Except for the little problem of heat. Space isn't cold, it's more of a giant Thermos bottle, and they gotta park in full sunlight, which is famously the only thing supplying the heat that keeps the entire planet alive. Good luck to them with their radiator setup.

But economically? There's no chance. Too expensive to get into space, too many auxiliary systems required, no maintenance is possible, and, given the lead time of prepping payloads for launch versus the rate of new developments in AI hardware, likely badly behind the times if not outright obsolete on the day of liftoff.

There is no shortage of land despite what some in the media would have you believe. Those same solar panels work at ground level. DCs don't have to be water guzzlers or grid destabilizers. They'd be better off by every metric solving terrestrial problems for the same money.

Of course they won't work. It's ludicrous that we have to even entertain the thought of otherwise.
