A practical superconductor is a huge deal, it would drastically change the way we deal with electrical power distribution and electromechanical applications. So any development is going to be big news. Though we’re not talking about an actual working conductor, it’s just excitement over research advancement, yeah? I’ve seen this kind of “big news” before in other tech sectors and time often proves it unworthy. If it does present a big step toward a practical superconductor that’s great, but I wouldn’t count any eggs yet.
