Starlink runs special rad-hard computers from AMD. None of that transfers to top of the line GPUs. This is crazy.

I am concerned, and haven’t seen anyone else point this out yet, that Musk will move Grok’s CSAM generation capabilities to space to be beyond the reach of terrestrial policing. Does this create some sort of legal loophole here so Musk can do this with impunity?

So my floating data center in international waters idea has potential investors?

Yeah, but there are enough people to buy the hype.

Earlier quoted context omitted.

You operate them like Microsoft's submerged data center project: you don't do maintenance, whatever fails fails. You start with enough redundancy in critical components like power and networking and accept that compute resources will slowly decrease as nodes fail No operational needs is obviously ... simplified. You still need to manage downlink capacity, station keeping, collision avoidance, etc. But for a large con…

Unless I missed something the Microsoft underwater data center was basically a publicity stunt. Anyone who thinks it makes sense to blast data centers into space has never seen how big and heavy they are, or thought about their immense power consumption, much less the challenge of radiating away that much waste heat into space.

I was listening to a Darknet Diaries episode where Maxie Reynolds seems to make it work: https://subseacloud.com/ I don't know how profitable they are, and I doubt this is scalable enough, but it can work as a business.

The way I read it, X AI is not really profitable and Elon's creditors/coinvestors asked for something tangible for their money, a.k.a shares in SpaceX, his only business that still has some solid foundation. The rest is emois.

I still don't understand the "data center in space" narrative. How are they going to solve the cooling issue?

Periodically send a crew to a comet to bring back a large slab of ice to put in the data center.

Either this is a straight up con, or Musk found a glitch in physics. It's extremely difficult to keep things cold in space.

Existing satellites manage to keep their equipment that already can consume several kW cool just fine. You might need space for radiators, but there is plenty space in space.

There's plenty of space in space, but there isn't plenty of space in rocket fairings, nor is there plenty of lift capacity for an unlimited amount of radiators.

Musk: "What do we have that OpenAi doesn't have?" Musk aide while high: "sPaCe" Slightly less high Musk aide: "But what is the synergy, where's the moat and how could that be done in practice and most importantly is there any limiting factor on Earth before we have to bring AI into.." Musk : "SPACE!!!!!!" It is incredible to think that the extremes of the stock market are actually pretty similar, pink sheets/cryptos…

This isn't really true, though? The ISS does it with radiators that are ~1/2 the area of its solar panels, and both should scale linearly with power?

ISS radiators run on water and ammonia. Think about how much a kg costs to lift to space and you'll see the economics of space data centers fall apart real fast. Plus, if the radiator springs a leak the satellite is scrap.
