But there’s lots of applications - computers that are orders of magnitude faster and use way less energy, maglev trains that are orders of magnitude cheaper. Think about how as electronics got cheaper they permeated nearly every aspect to the point that cheapo $20 gadgets probably have a simple microcontroller instead of an analog circuit. Room temperature semiconductors would be a material science breakthrough that would permeate every aspect of our lives within ~40 tears similar to how semiconductors did in the 1960s (assuming we got better and cheaper at manufacturing it at scale which would be the next challenge after confirmation).

That being said, I think it’s something we should remain hyper skeptical about as a prior because of the low likelihood and how difficult it is to verify superconductance (because the samples are so small they have to use roundabout techniques to establish it like the Meisner effect that can be confused with other properties because measuring 0 resistance itself is even harder and more error prone).
