It's the monorail. It's the same as the Hyperloop. Vaporware to distract from reality and actual progress.

On the one hand, you've got people with engineering degrees, writing detailed research papers describing exactly how to accomplish the task, designing hardware for companies that accomplishes the task, companies that are pouring billions of dollars into building such things, companies that have very related first-hand experience from operating 10,000+ satellites already.

On the other hand, you've got a career journalist, with a major in English language, who has never worked an IT, science, or engineering job at any point in their life (from their LinkedIn), who is calling all those people and companies idiot "tech bros" that don't know anything about engineering, claiming they've gone all this way while completely failing to think through the cooling requirements of building such a thing.

Hmm, I really wonder who's more likely to be correct here.

Anything that can be done in space can be done for less back on earth.

The only exception might be something that requires low gravity --- and a data center does not qualify. Or maybe if you're looking for a way to hype a space launch company.
