If you want to see all the conflicting findings and by-the-minute updates, this post is great: https://forums.spacebattles.com/threads/claims-of-room-temperature-and-ambient-pressure-superconductor.1106083/page-11?post=94266395

I’m very much not an expert, but my read of this is: most replication efforts have mostly failed when it comes to making a working room temp superconductor (meaning conducts electricity with no resistance). However, groups are increasingly seeing some of the other characteristics expected from superconductors, and it appears that the failures might just be caused by using an unrefined technique.

So time will tell, but this is probably a big advance, but not itself a world changer just yet.
