#2This isn't a particularly meaningful paper because they failed to produce any kind of partial levitation.
This one which finds substantial ferromagnetism and minimal diamagnetism is a far better reason to doubt that LK-99 is a superconductor:

Still very inconclusive because the synthesis is difficult and messy and nobody knows precisely what materials they're analyzing, but I've adjusted from cautious optimism to mostly resigned pessimism.

Wait till tomorrow when there will be a new not peer reviewed paper stating the contrary.

#5I think we'll eventually discover superconductivity isn't possible at STP

#8Now I don’t know what to believe.
The original scientists said that only 10% of their synthesis attempts were successful.
So at this point no one should be believing anything until we have a lot more evidence.

Superposition of it's over / we are so back.
