Are machines better at quantum physics than humans?

6:41 That's not really true. Almost all heat in electronics comes from the semiconductors (ie. transistors in the ICs). You could replace wires with superconductors, but you still need semiconductors (especially PN transitions) which dissipate a lot of power. A better use of superconductors is in high power transmission lines, where the resistance of the wire means significant losses. There are actually transmission lines made of superconductors with liquid nitrogen flowing around them in tubes to make them work.
