It is a comment on the absurdity of orbital data centers. Mountaintop data centers sound absurd, but are more feasible and efficient than orbital ones in nearly every aspect.

That's fine, if the argument for DC in space is just "Let's put them in the hardest place possible". Then less hard -> absurd, implies more harder -> more absurder.

But space based dc accomplish something that mountaintop dc do not. The different list of benefits/tradeoffs are why space DC are proposed and mountaintop ones are not. It's a difference of kind, not degree. It's not a meaningful experiment to just try to build DC in hard places and then we can finally validate space.

Stated benefits in particular:

- Power available 24/7 for "free"

- coms w/o interruption using existing infra

- Rideshare (SPX can build out capacity while other lifts pay some of the bill for lift)

- Nonregulation

- Very low latency to "places of interest far from USA mountains"

And no, I do not believe that mountaintop automatically satisfies these benefits in a smooth way such that mountaintop is a meaningful stepping stone towards space.

		> - Power available 24/7 for "free" The Sun is visible from Earth as well, the last time I checked. In LEO you don't get power 24/7 because you are only 500km above the Earth. Yes the Sun is more attenuated on Earth but what we care about is $/W not raw wattage, and Earth certainly has cheaper $/W than space. > - coms w/o interruption using existing infra I'm perplexed how comms might be easier in space than on Earth where you can just run a cable. > - Rideshare (SPX can build out capacity while other lifts pay some of the bill for lift) On Earth you don't need to rideshare because you don't have to ride a rocket. > - Nonregulation Space is more regulated than Earth. The only way to get to space is via a rocket which is the same as an ICBM. Governments regulate the process of building ICBMs and what payloads can ride on them. If you want non-regulation then go to international waters or find a bribable government. > - Very low latency to "places of interest far from USA mountains" The latency is not terrible in LEO but it's nowhere near as good as on Earth.
