Conclusions
Orbital data centers look more viable than we expected going in and the case rests primarily on launch cost. The engineering challenges seem significant but none appear intractable. Commercial off-the-shelf solar, passive radiators, and standard error-correcting codes seem sufficient for a baseline architecture. We expect limited demos and shipments of compute to orbit in the coming years but our best estimate is that orbital data centers are unlikely to represent a meaningful share of compute before 2030. They might scale quickly thereafter however, and are more likely to be bottlenecked by chip production rates rather than by launch cadence. A generally important dynamic is that terrestrial data centers likely face headwinds that worsen as compute scales up while orbital data centers face constraints that relax with scale.

And all those conclusions take is cost to space to reduce 15 times; new cooling tech that isn't used anywhere to work at scale but only in space (if ground datacenters can use it too, their cost decrease); that ops cost line to not do anything useful so it can be just dropped; those 10mm radiation shields to not weight anything, because they didn't enter the costs; and that ground datacenters to use more expensive tech than they use today (just not improving is not enough).
We will have space datacenters some day. But I'm not holding my breath.
This is complete bullshit.
Anyone who thinks we’ll have data centres in space before we have a civilisation changing step up in surface to orbit space drives and materials science is an idiot.
How the hell does anyone think a rocket is ever going to compete with a prime mover towing two trailers, or an ocean going vessel.
We’re not exactly short of land.
And no, space is not cold.
