"Literally not a single purely commercially-backed nuke plant has ever been built in 70+ years. Not one."

Sure, let's check wikipedia to see how this is not true : https://en.wikipedia.org/wiki/List_of_commercial_nuclear_rea...

Also, after googling it: yes indeed, in some countries renewable energies are more competitive than fission. But that's not the case everywhere : https://www.iea.org/reports/projected-costs-of-generating-el... Or maybe you were just talking about the US, in this case your statement might be true.

I hope renewable energies cost will keep decreasing as much as it did those last ten years but I'm not as optimistic as you are.
