So, for the sake of the thread let's assume this is real as you've asked. In the next months and years the focus will be on "is this useful" and "how can we make this useful". To make use of a sc you need to bring it into shapes we can use. Wires of all sizes and shapes are the big one. Can this material be made into wires like current sc (bonding to a base material to fix the brittleness) or even better can it be drawn into wires? If not, that's a new research area. Also, we still have no real idea how high temperature sc work (there are two competing theories, but afaik neither can fully describe what we see). That's probably even more important for this new ones. A flurry of research will be into related materials, to see if we can find ones which combine the sc with better properties, but having a theoretical understanding would make this far easier than just randomly poking at materials. So, assuming we get to the state of usable room-temp sc everything else depends on the price. The lower the price the more they can replace until in the last instance all cables, coils and everything could use them (this will probably not happen for a very long time if ever). In the nearer future they could replace all of their predecessors in places where they are used today: In MRTs, in the LHC and comparable machines, fusion reactors, various cables, some small energy storage systems using them already. Such things. They also could solve the biggest remaining obstacle for renewable grids based on wind and solar (storage) by allowing far better SMES: https://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage https://en.wikipedia.org/wiki/Superconducting_magnetic_energ... Who knows where we'll go from there, but I think that's enough food for thought for the moment.
