Elon Musk actually confirmed a clip from my interview with Dylan Patel where he says they've got like 200,000 GPUs already up and they purchased a new factory in Memphis and they're building out a new data center. There's the craziness they did with like mobile generators. Well, now they just bought a a power plant from overseas and are shipping it to the US because they couldn't get a power plant uh you know new one in time.So like this is going to power his next generation of supercomput powering X AI. ...
