This document explains it well. (The resistance of the interconnect is not even mentioned as a significant component of power consumption.)

You can synthesize superconducting FETs though: https://link.springer.com/chapter/10.1007/978-94-011-1918-4_...

Obviously this isn't much benefit since the vast majority of applications can't be liquid nitrogen cooled (and computing has followed "what consumers will buy" on progress).

That changes substantially if superconductors will keep working when put in my pocket.
