Well said. I had a small version of this debate with someone I know who posts political stuff on FB, who pointed out in absolutist fashion that the poor failure modes of nuclear and the regular emissions from dirtier sources are both bad, and we need something without either downside.

Literally true but has a bit of "perfect as the enemy of the good" to it. I know absolutely nothing about the challenges involved in updating existing infrastructure to a different source but it seems like an immense challenge, and not at all black and white.
