Even if it does, it's a ceramic which makes its very limited for usability and you won't see it in an MRI machine or transmission line like the media wants you to believe. Also we actually already have some high temp super conducting ceramics.
We need a metallic high temperature super conductor.
What room+ temperature ceramic superconductors are there? Why would this not still be immensely useful anywhere a ceramic superconductor is currently used?
I didn't say other superconductors were not useful. I was saying that one that can be used at higher, room temperature temps is at the very least a new, useful thing. That calling it "limited in usability" is odd when existing ceramic superconductors with considerably cooler temperature requirements are already useful?

This will be sufficient as soon as you can find a way to market a smartphone that only works while standing in a freezer. There's a world of difference between "above the boiling point of liquid nitrogen" and "in a room that people can use consumer electronics in."
Imagine winning the online bet after it drops to < 5% confidence. Yum.
Why are we supposed to believe this new paper? Realistically there’s nothing here. This is an announcement of an announcement.
All we can do is speculate. And I speculate that if there were a room temperature superconductor, it would have been proven in the first paper. That’s the point of a paper.
If this article is true (i.e. the quoted bullet points were actually said by Kwon) I would feel a bit more optimistic. I haven't checked the veracity at all.
The metaculus wager says replication within 15 months. Point #2 #3 #5 & #8(!) is that this stuff is really really hard to make. Point #6 is pretty noncommittal about how long till the recipe is published (in the context of 20 years of work).
But let's stop deceiving everyone into thinking everything using superconducting wires/cables will magically become room-temperature if LK-99 is real. They won't, you don't make such things from brittle ceramic.
Is there use for almost-superconductors? E.g. could you take fine room-temperature superconductor powder, stick it into copper or sth and have something that's a fraction of resistivity of copper (but not 0)?
My money is still on LK-99 being a finicky topological (only conducts in one direction) superconductor.
Its what the simulations suggest. It would explain why the replication attempts failed.
Its perhaps no world-saving bulk superconductor, but that still seems like a fascinating material for, say, microelectronics or high power electronics. For instance, what if foundries could align it and work it into a metal layer for microchips? Maybe they could take advantage of the directionality to make a gate out of it.

So, a 104K superconductor is well within the range of being practically useful.
But there are no applicable uses as of now outside a lab.

EDIT: actually it’s 1%, so you’d 100x your money: https://www.metaculus.com/questions/18177/room-temp-supercon...

It'd be damn nice if he were right though.
No matter what, if it were bonefide it would be interesting.

There’s probably many meters of electrical traces in my iPhone’s logic board and ICs, most of which are presumably copper, but don’t need to be.
The whole outer case of my phone is made of ceramic so it doesn’t seem like it would be a problem.
Antennas in mobile phones, EM shielding for sensitive amplifiers, motherboard circuitry, etc, etc...
