Because a LOT of people are missing the point:

No, Elon Musk is NOT serious about putting a million data centres into orbit. It can't work: laws of physics say "nope".

But SpaceX is expected to go public this year.

Elon is talking up his company's future prospects in front of gullible investors because he needs a growth narrative beyond Starlink, which is already priced in. Something to justify the Starship proram beyond NASA's lunar ambitions.

So it's salesman's bullshit, lies for fools.

@cstross it also provides a fig leaf of justification for a public SpaceX to shovel money to xAI when “because I want to” becomes harder to justify. They’ll need somebody to provide expert design partnership to solve these difficult technical problems. (Or the other way around if required.)
