This is the curse of popular science websites hyping things up; most people, present company included, have no idea what the scientific language means - be it superconductivity, LHC results, or astronomic spectrography.

So popular science wraps it in a "what you could do with it. maybe. possibly." Or what it means. And commenters have latched onto it, but a lot is said with an air of confidence, of just-so. "Oh uh, superconductors, conducting is passing electricity from one end to the next, super is like really good, uuh uh uh... I know, what about power lines from the Sahara to Europe so they can build solar collectors down there!"

Same with exoplanets, the actual science is "yeah the luminosity of this star drops by 0.0003% at a cycle of 300 days and we're getting some photons that indicate there may be hydrogen molecules", pop sci turns that into "EARTH-2 TEEMING WITH LIFE DISCOVERED, GENERATION SHIP WHEN?"
