The potential for tech miniaturization alone is a massive deal.
Right now, one of the biggest obstacles toward packing more transistors into a given space is the fact that they radiate a shit ton of heat which must be removed by close to immediate contact with the heat sink.
Without the need to deal with a shit ton of waste heat, instead of only having one, or only a couple layers of transistors in a processor, you can stack that shit high. Volumetric processing. Instead of wider chips, we could have taller chips. Hell we could stop calling them chips, and start calling them blocks!
If our processors could be as dense vertically as they are horizontally, we would see entire orders of magnitude more processing power, and, because a lot of energy is not being lost to heat, it's actually being used productively. Or in other words, you need less energy and yet can accomplish even more work.
The overwhelming majority of the heat from processors is not from resistive power dissipation, it's from transistors switching state. This will not go away because of superconductors.
I read in another comment somewhere that introducing a superconductor wouldn't change the properties of the semiconductor bits. So the transistors themselves would still produce heat. But there are also full-conductor bits that produce heat that might be eliminated.
