Well, except for the whole "research over the last decade or two has born superconductors that work at warmer and warmer temperatures" thing. Superconductors look far more promising than the economics of nuclear power (which have gotten worse, not better) or fusion (still perpetually 20+ years out), and it's a critical field to work on because we desperately need stuff that superconducts at LN2 (or warmer) temperatures for things like medical imaging, because we're going to run out of helium completely in 100-200 years (and it will become wildly uneconomical well before then.)

tbf there are nitrogen-temperature superconductors already, they just aren't easy to produce or work with.

It's half-truth, higher temperatures usually require high non-ambient pressure to achieve superconductivity.

Look for Yttrium-Barium-Copper oxide that superconducts when cooled with liquid nitrogen. This is "cheap" cooling that will never run out. https://www.kjmagnetics.com/blog.asp?p=superconductors#:~:text=Yttrium%2Dbarium%2Dcopper%2Doxide,boils%20at%2077K%20(%2D196C) https://www.kjmagnetics.com/blog.asp?p=superconductors#:~:te....
