It is my understanding that the fundamental architecture (the general purpose transformer) is identical between the "AI" used by Black Rock and by OpenAI
If you have some evidence to the contrary I'd always appreciate the chance to learn.
But the transformer based architecture is fundamentally flawed: it will always hallucinate.
I'm pro nuclear as well but we absolutely can maintain this level of energy consumption on renewables alone.
The question is cost and risk - I'm for diversification of our grid which includes nuclear.
But it is getting to the point where renewables with backups will be cheaper than coal. That's absolutely something you can run the entire grid off of. You can balance storage requirements with excess production capacity that gets shuttered over the summer etc etc
