We also shouldn't overlook the fact that the proposal entirely glosses over the implication of the alternative benefits we might realize if humanity achieved the incredible engineering and technical capacity necessary to make this version of space AI happen.

A lot of great inventions we now take for granted initially came with little motivation other than being able to kill each other more effectively. GPS, radar, jet engines, drones, super glue, microwaves, canned food, computers, even the internet. Contrary to the narrative of the internet being about sharing science, ARPANET was pushed by the DoD as a means of maintaining comms during nuclear war. It was then adopted…

The digital internet began with the telegraphy network in the early 1800s.

Many, many network protocols were developed and used.

This vision doesn't come from those great engineers, but from Elon, the guy who promised Hyperloop, FSD in 2 years 10 years ago, and lots of other BS

Only people who never interacted with data center reliability think it's doable to maintain servers with no human intervention.

There are a class of people who may seem smart until they start talking about a subject you know about. Hank Green is a great example of this. For many on HN, Elon buying Twitter was a wake up call because he suddenly started talking about software and servers and data centers and reliability and a ton of people with experience with those things were like "oh... this guy's an idiot". Data centers in space are exactly…

> but they cost 1000x as much

Compute power has increased more than 1000x while the cost came down.

I recall paying $3000 for my first IBM PC.

> they need to last years and not fail

Not if they are cheap enough to build and launch. Quantity has a quality all its own.

SpaceX is too big to fail. It's important for national security. I wonder if Elon wants to tangle all his businesses into SpaceX so they are all kept afloat by SpaceX's importance.

Simply put, yes.

This is not good for SpaceX. It's a less valuable company with X and xAI. But it helps Elon make it look like he runs two successful businesses.

Earth does have plenty of sand and iron. Literally all you have to do is grow the sand into a crystal, slice it up, etch some patterns onto it, then add some metal.

Making only 1TW of pv cells per year is a skill issue.

Sorry but who buys this bullcrap? Sure you can take a tesla and drive it in your bedroom to use its AC, because you make teslas, but you could also use just a window attached AC?

Elon can't legally financially entangle Tesla to SpaceX due to Tesla being a public company, so his hands are tied. Tesla is clearly benefiting from protectionism and its sales would collapse if BYD were allowed to openly sell in the US. Most people just want affordable, maintainable and reliable cars.

I've been thinking about this recently as I hear it often. Would people who want to buy a car in the Tesla price range really choose a slightly cheaper Chinese EV if those were available?

Personally I have a hard time believing this. But even if you had similarly priced Chinese options, I would guess the main reason for buying a Tesla is not just because you want an EV. While a Tesla will be a reliable baseline EV, surely the reason you (or at least I) would buy one is for the supervised self-driving feature.

Well surely this acquisition is above board. Nothing funny going on here, just good old business as usual.

And hey, look at that, pure coincidence, Tesla just gave xAI $2B! Now it's back in Musk's private pockets! How handy!
