It sounds like their vision for space-based data centers presupposes nearly-free energy costs, delivered via a colossal solar farm made possible by falling launch costs.

Temporarily putting aside (extremely fair) feasibility questions around those two pre-requisites, data centers are a not-bad choice for things to do with unlimited space energy.

Aluminum smelting or growing food are the two I’d think of otherwise, and neither of those can have inputs/outputs beamed to a global network of high-bandwidth satellites.

Solar energy isn’t that much more efficient in Earth orbit than on Earth - maybe twice as efficient. That sounds nice, but you’re saving half of your solar panel cost while massively increasing every other cost.

The one benefit is being able to be in a synchronous orbit with the sun, so you don’t have to contend with night. However, that’s just another ~doubling of efficiency, which I think still nowhere near makes up for the additional costs.
