Like their section on collision avoidance isn't any more sophisticated than "Starlink has a great record so far" when we're talking about a very different scale of how much mass and surface area has to be moved around in a coordinated way.
This is in effect an editorial from two postgrads, not an actual detailed workup. I don't feel like spending time going into any more effort based on that.

Do that, and you can quickly bootstrap an orbital ring and make rockets obsolete from surface to orbit of either body.
In the case of Mars, the planet-wide dust storms make it a good idea to locate your PV off-planet, and an orbital ring is also very convenient for that.

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.

Starcloud-1 is already in orbit, and many other plans by them and other firms are already well into development.
And Lonestar has a backup server on the moon. Seriously.

What are Hyperloop/Boring actually doing now? It doesn't take that much investment to human-drive a 10-20 Teslas up and down the Vegas Strip in a straight tunnel at normal speeds.

I mean, Elon will probably shoot some GPUs up there and call it a success, but I'm not sure that should could at "data centers in space."

Silliness aside, has anyone come up with a cooling system that would work well for a friggin data center in space? Or is it still all just a wishful thinking game, ignoring physics?

That's perfectly viable.
However at the temperatures chips operate at, because stuff on the ground is getting convective cooling as well as radiative, a radiator designed for LEO will reject slightly more heat on the ground than it would in orbit.

Heck for $50/kg I could see it, too. Now with Falcon 9 or Heavy it's on the order of thousands, isn't it? Just need a measly two orders of magnitude improvement and then we can start talking.

If that workload does expand in usage, and the economics of orbital DCs make sense (with high launch costs, zero ability to do maintenance, and weight penalties for shielding and radiators), then surely ocean based data centers (e.g. Panthalassa) make more sense (lower 'launch' costs, high latency on maintenance, no weight penalties), and if those make sense then surely the distributed land based facilities (e.g. Rune Energy) or home based facilities (e.g. Span XFRA) make even more sense (easier maintenance, low/no permitting overhead because they're covered by existing permits, reasonable quality terrestrial fiber internet).
