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 itโ€™s interesting how he keeps talking about solar energy, still, while the rest of the right wing mysteriously seem not to. How far off the predictions in your essay about him & space & solar energy collection are we, I wonder. (Did he get lapped by the cost of batteries dropping as they have? It seems likely.)
@dubiousblur Remember he owns massive battery factories. However, China more or less has a monopoly on PV panel manufacturing.
@cstross @dubiousblur I remember reading somewhere that in China BYD makes batteries for Tesla, so they may well be losing their edge there as well.
