So, Musk has used one of his companies (SpaceX) to buy another (xAI). The value of this combined firm is $1.25 trillion, although contextually that's something of a made-up number as there's insufficient trade of stocks (that isn't Musk himself) to really know what either is really worth.
What I did find odd was to see a justification for the merger including "orbital data centres". I think there's a problem here.
A massive problem with AI data centres is heat production - all those microchips producing oodles of heat. Hence all the stuff about problems with water usage for cooling. Heat moves by convection, conduction, and radiation. But because of the nature of a vacuum, there's no convection and conduction, just radiation. This means that it's very hard to get rid of heat in space when compared to Earth. Space is not necessarily cold - vacuum doesn't have a temperature, because there has to be something there to have temperature. About where we are in the solar system, anything facing the sun long enough is going to heat up to over 100C: things like an AI datacentre that needs solar panels facing the sun. An AI data centre that's also producing whopping oodles of heat because of all the microchips. So unless Elon Musk has discovered some incredible kind of super heat radiation device no-one else knows about, his space data centres are going to burn up very quickly. That's on top of the genuinely absurd costs of getting everything into space and maintaining it whilst it's up there.
The long and short of it: orbital data centres are, by my understanding of physics (which is not the highest) somewhere between practically and economically impossible by any tech we'll have for decades, and someone proposing them in this manner is potentially lying to conceal something.
