Elon is smart and employs many smart people. If the thermodynamics didn't work, they would know. I do wonder if shielding the multi-billion transistor GPUs will be a difficult.

Like the hyperloop?...
- damnitbuilds 5mo ago
  The problem with that was not based on physics, like the thermodynamics of datacenters in space.

Like point to point rocket travel?

  That works, the physics is proven. It has not been tried commercially yet, so has not failed there, but that is not relevant to my point.

Just shield them under the tons of heat radiators they’ll be deploying. One ton of compute will > 1 ton of hardware to radiate the waste heat. Does anyone know the multiplier?

  Radiators need to be flat and thin - not really good for radiation shielding. But guess if you use some sort of fluid in them, you could use a reservoir of it for shielding something.

  The radiators would be a lot smaller than you’d think: <https://www.youtube.com/watch?v=FlQYU3m1e80 https://www.youtube.com/watch?v=FlQYU3m1e80>.

The smart people don't care what the endgoal is. They are happily enjoying themselves building hightec. And they earn a lot of money doing so. Elon Musk on the other hand has a construct of multiply billion dollar companies he has to feed and keep alive: xAI investment burns one Billion per month. Space X makes 8 Billion per year. X cost him 40 Billion when he bought it but is not profitable. Tesla struggles to grow, had the very costly Cybertruck, and has a lot more opposition than 10 years ago. I do not understand at all what his endgame is. His finances are hidden enough. But his motivation is for sure selling his story. his story is the future and it doesn't matter very much if its doable or not or usefull. Tesla as a company is still overevaluated for years now. If Tesla would drop to what its worth, Musk might need to pay back a lot of loans and other stuff and he might just be gone. He said often enough in public that it was very close etc. If Space-X and Tesla wouljd just be good running companies with profits in the billions, he wouldn't need to be that weird but it could just be that he believes in it here are plenty of interviews showing him not knowing that much about his technology. He is not the expert, he is the pusher and unblocker

  That's a lot of alleged failure for one of the richest people in history. Maybe you should go start a car company and launch company and show us how it's done

    So your comment is just appeal to authority?
    - whamlastxmas 5mo ago
      it's an appeal to net worth and the argument that you don't become the richest person on the planet by being a massive idiot that everyone likes to paint him out as. he's problematic and sucks but he's not an idiot (in business)
