Interesting to see this alongside "Physicists Have Identified a Metal That Conducts Electricity But Not Heat" which is talking about another material where electrons exhibit collective behavior, "moving as a fluid". Perhaps there are a number of situations where electrons coordinate within a metallic lattice, but something additional is required to produce superconductivity. Cooper pairs could be degenerate (or at least very simple) forms of this collective behavior. Or maybe vanadium oxide is a room temperature superconductor, it's just that any amount of current destroys the effect unless it's really cold, cold enough for everything to stay put.
