It would be unlikely for the first observed room temperature superconductor to also be practical. LK99 contains lead which is something we are trying remove from consumer electronics.

What matters is all the investment and attention that would follow the verified discovery of such a material, the huge glut of research would surely yield even better candidates.

The ideal end goal is something like the superconducting tape that we already have, but that works without cooling and is preferably non-toxic.
