https://news.ycombinator.com/item?id=16523268 links to the Nature abstract showing it's critical temperature is under 2 kelvin, so that's low even for cryogenic superconductors.

It's interesting because it's very high temperature given certain properties of the material; if that is confirmed, it may allow greater understanding of superconductivity, which may allow other materials to work at higher temperatures.

Damn! But any movement is promising. Thanks

If that’s what floats your boat (sorry) then you might want to look into topological superconductors, which I think might be the way to go. The whole field of topological materials is new enough to hide something surprising and promising.
