Cooling is conspicuously absent other than a brief mention in the conclusion. As if it has been redacted, because it’s such an obvious and hard problem in space. Which leads me to believe they’ve made progress and aren’t sharing that for competitive reasons. There’s an extremely strong incentive for SpaceX to put GPU on board their birds for local SDR processing power, for applications like SIGINT, high channel counts, etc, and the cooling is literally the only impediment.
In fact everything in this paper is already solved by SpaceX except GPU cooling.

It's not absent - it's covered in the paper, which this blog release summarizes. There's a link to the paper itself in the side bar.

Cooling is already solved by SpaceX too, since this paper basically starts with the idea of swapping out whatever payload is on Starlink with power-equivalent in TPUs, and then goes from there.
