> The superconducting-like behavior in LK-99 most likely originates from a magnitude reduction in resistivity caused by the first-order structural phase transition of Cu2S

The preprint you are citing is explicitly dismisses the sharp transition seen as being non-superconducting.

Nah, I know. But it still looks like a similar material, no?

Even if it looks unlikely to be superconducting, I still think people should remain level headed about it. They spent a lot of time and effort on it.
