"It's not that extraordinary."
How is that possibly true? LK-99 is already amongst the highest-temperature superconductors ever found (with that claim substantiated by at least two independent research teams as of this moment).

People are way, way overconfident. Most people in the field would not be willing to put it at >50% odds at this point.
Do you have a source for this claim? It sounds like you just made it up.
But, for what it's worth, as both an LK-99 optimist and as someone who has worked in the field and who still talks to people in it, most people in it seem to put the chances well below 50%.
That leaves the original, that is clearly diamagnetism, but still could be misleading in many ways.
We don't know how many labs are working on replicating this. So we have no idea how unlikely mistakes we should expect to see.
