"Infrastructure investment" is not fungible. There's either demand for this power where they're adding it, or there's not. If there is demand, then it's created by AI. If there's not (i.e. AI bubble pops), then there's excess capacity where we don't need it.

Can you or anyone else please take us through this likely outcome?

I'm glad that individuals with no democratic control are allowed to declare large swaths of society to suffering because, maybe, in the future things might get better.

FWIW, it took nearly 150 years for commoners to benefit from the industrial revolution. The idea that I must suffer and my children must suffer and their children must suffer so some future plutocrat can get a fatter nut is pathetic.

It's not a good thing when said infrastructure produces ridiculously dangerous waste & fallout risk though.
