Are machines better at quantum physics than humans?

This is a little nit picky, but you mentioned that room temperature super conductors would mean that laptops and cellphones wouldn't get hot. That isn't actually true, because current computer technology relies on semi-conductors, with variable resistances to allow for high current (a one) or low current (a zero). That variable resistance would generate heat when current passes through them.

The place where room-temperature superconductors would help the most would probably be with transmission lines, because you could then reliably transmit power across a continent with minimal loss. That would allow you to do cool things like setting up solar panels in different time zones to transmit power from sunlit areas to nighttime areas (i.e. France to China when it is daytime in France and nighttime in China).
