Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

This Twitter post from the guy who was synthesising the stuff in the US seems convincing: https://twitter.com/andrewmccalip/status/1689476909208600576

Not a superconductor - the hints of superconductor-like properties were due to a combination of iron contamination in the Pb forming iron fragments which (surprise!) show ferromagnetism & Copper Sulphide which shows a very similarly anomalous temp/resistivity profile (but is not a superconductor).

The most likely outcome (i.e., not a superconductor, lab error due to honest scientists being fooled by their own experiments) seems to be probably the true one.
