How hard is it to build orbital data centers, actually? (arstechnica.com)

Editor’s note: … In this article, we discuss the technical challenges of building an orbital data center constellation: launching all of it, dissipating heat in space, dealing with radiation, and addressing latency issues in orbit. Read part one here.

I find the napkin math interesting, especially putting into light that given expected longevity of such satellites, 5 to 7 years, they will have to do 10 to 42 launches per day. SpaceX will need $1.5 to $10 trillions to make it happen. All of that so the slop machine doesn’t have to run into obstacles like democracy ? So it can destroy communities and the environment freely? What are we doing?

Launch costs (yeah, Musk promised 100 tons to LEO Real Cheap, Real Soon, you better believe it) and energy requirements for launch kill this. If you could make DCs ISRU in space, well, good luck with that.

Boy, this superbubble is astronomic. Be sure to watch it when it blows.

Musk promised

Hyperloops Mars bases Moon bases Interplanetary travel 1000x cheaper tunnels for trains Travel by ballistic missiles to the other side of the world Rocket powered cars Electric cargo trucks The roadster AI that would be truthful AI powered robots

Just a small list of all the promises from Elmo but let this make clear that if the word comes from Elmo's mouth, then its a lie

The guy literary can only lie
