"(room-temp. superconductivity) would deliver nearly unlimited energy, turbocharge compute speeds, and introduce new and better ways to use computers and other electronics." How so? It would save a few percent in transmission losses, make various quantum sensors possible/cheaper, just maybe, levitating trains, if it's cheap enough. Unlimited energy? lol. I did a double-take when I checked the publication. I can't believe this is in the ACM journal.
