## Quote — verbatim

> GPT-4 was trained I believe on a 100 megawatt capacity data center, and that grows to about \[2\]50 megawatt capacity for the newer model... and the next tier is 1.2 gigawatt. When you get to 1.2 gigawatt, that means it's a nuclear reactor — nuclear reactor produces 1 gigawatt. We can't do solar... we just don't have enough storage capacity for solar. So it is going to be nuclear, and Microsoft just bought a nuclear reactor in Pennsylvania.

He says power needed for AI grows by roughly half an order of magnitude per year, and notes Oracle's reactor plans and banks financing nuclear — "such an opportunity right now to decentralize power."
