Maybe, but the same was already said when cuprate SC appeared in the late eighties with their relatively high critical T°, but they haven't really fulfilled their promise…

Are they really the same though? I mean we are talking about room temperature, not the"(relatively) high temperature", a term that is arguably misleading to a layperson.

I'd imagine most people who are informed of the difference would recognize that cuprate SC is nowhere near as useful.

Every article older than a couple weeks talking about superconductors goes on and on about how useful they are, except for the logistics of keeping them cold

Example: https://en.m.wikipedia.org/wiki/Superconducting_magnetic_ene...

Superconductors suporting high current are incredibly useful, but that's a big caveat. There's a reason MRI scans still use the super tedious helium-cooling instead of a much simpler nitrogen cooking allowed by cuprates: the cuprates SC aren't good enough for MRI.

Iirc the LHC experiment would not be possible without those superconductors. That’s a pretty big deal.
