I was talking to someone about this the other day. I was part of a team at NASA that developed a cooling system for the ISS and this whole premise makes no sense to me.

1. Getting things to space is incredibly expensive

2. Ingress/egress are almost always a major bottleneck - how is bandwidth cheaper in space?

3. Chips must be “Rad-hard” - that is do more error correcting from ionizing radiation - there were entire teams at NASA dedicated to special hardware for this.

4. Gravity and atmospheric pressure actually do wonders for easy cooling. Heat is not dissipated in space like we are all used to and you must burn additional energy trying to move the heat generated away from source.

5. Energy production will be cheaper from earth due to mass manufacturing of necessary components in energy systems - space energy systems need novel technology where economies of scale are lost.

Would love for someone to make the case for why it actually makes total sense, because it’s really hard to see for me!

Elon musk has a history of making improbable-sounding promises (buy a tesla now, by 2018 it will be a self-driving robotaxi earning money while you sleep, humanoid robots, hyperloops).

The majority of these promises have sounded cool enough to enough people that the stock associated with him (TSLA) has made people literal millionaires just by holding onto the stock, and more and more people have bought in and thus have a financial interest in Musk's ventures being seen in a good light (since TSLA stock does not go up or down based on tesla's performance, it goes up or down based on the vibes of elon musk. It is not a car company stock, it is an elon vibes check).

The thing he's saying now pattern matches to be pretty similar, and so given Musk's goal is to gain money, and he gains money by TSLA and SpaceX stock going up, this makes perfect sense as a thing to say and even make minor motions towards in order to make him richer.

People will support it too since it pattern matches with the thing prior TSLA holders got rich off of, and so people will want to keep the musk vibes high so that their own $tsla holdings go to the moon.

Make sense now?

The story here is even simpler. SpaceX is going public this year. Elon made a monumentally shitty investment in Twitter and then poured a stupid amount of money into xAI at the peak of the cycle. By having SpaceX buy xAI, he gets to swap worthless shares in that company for more SpaceX liquidity. Simple as that.

Exactly, and there needs to be some economic justification for a giant rocket. There is no money to be made by going to Mars, and AI data centers in space could attract investors (who are just riding the data center hype).

I find this to be the most obvious game plan here. Makes total sense from financial engineering point of view.

You _might_ get to develop nice tech/IP to enable other space based businesses at the same time. "we sold them on X but delivered Y". So it's a bit of a hail mary, but makes total sense to me if you want to have a large budget for inventing the future.

Once you can demonstrate even a fraction of this capability of operations ... I think you can sell a "space dominance" offering to Pentagon for example and just keep pedaling.

"We are going to build the perfect weapon" does not necessarily entice as large engineer population as "we are going to Star Trek".

Another thing - if Moon is going to be a thing, then _properties on Moon_ are going to be a thing.

In theories of value in post-ai societies scarce assets like land are going to become more valuable. So it's a long term plan that makes sense if you believe Moon will be a realestate market.
