I'm not holding my breath for room temperature semiconductors anymore. I've gotten excited too many times. If they come, great. If they don't, no emotional investment here.

What interested me with this line of research is that it seems like even if they are completely wrong about it being superconductive, it looked like they might be on to some novel electromagnetic effects, which while not as exciting as hover trains or long haul EVs, might mean punctuated improvements in more mundane items.
