A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging:

I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback preventing construction on Earth.

I can't find the original article but here is one about datacenter pushback:

But even if political pushback on Earth is the real reason, it still seems datacenters in space are extremely technically challenging/impossible to build.

The real reason is, Elon has SpaceX and xAI. He can create an illusion of synergy and orders of magnitude advancements to boost the market cap and pocket all the money. He realized long time ago you don't need to deliver to play the market cap game, in fact it's better if you are selling a story far in the future rather than a something you can deliver now.

both can be true, he can excel at 'narrative' and also deliver me my Tesla and my starlink, it's not either or

>>dubeye+MD1
Ok, he delivered your Tesla and your Starlink, but so far he has hasn't delivered your Robotaxi, your Optimus, your lunar lander, your space datacenter etc. And the list keeps getting longer instead of shorter...

You don't have to win them all.

He does (or at least a good proportion) if you want to use as precedent for delivering on these promises, though. Especially for the larger more extreme statements and not just buying himself into an existing business.

Why does he?

that's an arbitrary standard set by you.

His investors are quite happy with his success rate. He is constantly building new stuff. And as a consumer who has had great experience with every product I've bought, so am I

No one buys into Elon's firms because he's expecting dividends.

His investors are not investing because of his success rate in delivering on his promises. His investors are investing exclusively because they believe that stock they buy now will be worth more tomorrow. They all know that's most likely not because Elon delivers anything concrete (because he only does that in what, 20% of cases?), but because Elon rides the hype train harder tomorrow. But they don't care if it's hype or substance, as long as numbers go up.

Elon's investors are happy with his success rate only in terms of continuously generating hype. Which, I have to admit, he's been able to keep up longer now than I ever thought possible.
