An entirely new category of superconductor could well be revolutionary even at this temperature, for several reasons. It could be the first one of a family with variants that go up to room temperature. It could be cheaper to produce or have other desirable properties for commercial applications. And it could lead to advances in theory that would allow prediction of other unknown superconductors.

First, at a minimum it validates that the researchers found a novel rare superconductor at ambient pressure, and are not frauds.

Second, the new mechanism of superconductivity may lead scientists to explore other materials with similar properties that may work better.

Third, the synthesis may not be completely spot on yet. It has been just 4 days of attempting replication, and this result is pretty good in that context.

This is not about 110K, this is about trying to verify the results related to LK-99.

The LK-99 that is room temp superconductive seems quite difficult to produce at this early stage. But these researchers were able to produce their not-as-good version of LK-99 and at least verify very close to superconductivity at 110K. This makes the LK-99 room temp superconductivity claims that much more plausible.

Is my understanding correct that 100k at ambient pressure is pretty special on its own?

That's what I'm not understanding about this frenzy. Seems like this already kind of exists?
