Data Centers in Space are a practical engineering impossibility, as well as making no economic sense. Engineering and the laws of physics get on the way.

Just because Scott Manley refuses to call that out, so he can do another eight videos about it, don´t stop listening to somebody with the feet on the ground:

I don't think they are impossible, just impractically expensive. That should be no problem for AI companies and their infinite access to capital. Nobody wants datacenters to be built around here on the ground, so I say get to spending.

If it ends up bankrupting them, even better.

Good thing Elon's companies have a history of moving engineering impossibilities from impossible to slightly late.

Remember when globally competitive electric cars, re-usable boosters, catching a rocket with chopsticks, playing a fps game via a brain implant, and maintaining a satellite constellation at 480km LEO were also impossible?

the way the crony capitalism economy works, it will bankrupt all of us well before it does the AI companies...

There's a difference between "infeasible given materials and manufacturing capabilities of the time" and "infeasible as a scalable solution due to the laws of physics"

Almost no one said those were impossible, just hard. This is completely different. Rather like... a train in a vacuum tube hard. Definitely harder than making a subway with autonomous trains under a modern city. And much harder than being a third rate AI lab, though Elon did hit that target perfectly.
