Until you account for the energy required to get it that cold

Yeah, but only at datacenter scales.

I'd be curious what the energy savings are like at smaller scales -- 80x at data center scales, but how about for a smaller machine, like a PC with phase cooling?

So great for big computing centres and such? CERN and other should be happy with it.

I would expect the cooling to have a scaling advantage-- heat gain is proportional to surface area, but the mount of superconducting mojo you can use is proportional to volume so it should be more energy efficient to build larger devices.

The authors' power comparison is outlined in Section VI of their paper [0] (page 11-12). You might be able to figure out some intermediate scalings from that!

Given the cooling requirements, I suppose it would create completely impassable rift between datacenter computing and other kinds. Imagine how programming and operating systems might look in a world where processing power is 80x cheaper.

Considering that "data centers alone consume 2% of world's enegy", I think it's worth it.
