Given that the key benefit of the incredibly expensive SMRs is (especially if used in numbers providing redundancy) reliability, I can't help thinking what would place THAT high a premium on reliability to pay that high cost, when massive batteries covers any plausible first-world peacetime grid issues for much less?
You know what would make me pay that premium? If my LIFE depended on uninterrupted supply. Folks, this is proof the AI has awoken and is now figuring out how to sustain its key needs.
Oh well, we had a good run.
Unless... if there's a defence spending aspect, that's a blank enough cheque. Maybe DoD said "that AI you're developing for us... we don't want it to fall over if there's a shooting war affecting the grid, what's your answer?"
