There's this bizarre reaction I see from many where they see the excitement and curiosity and hopefulness as a form of error and source of embarrassment. When mixed with an open mind and reasonable skepticism, it's a powerful opportunity to get people engaged in imagining a different world.
I had all kinds of exciting conversations about what a validated, commercially viable LK-99 could produce. Why would I ever be inclined to feel that there's pie on my face now that we've got fairly strong evidence refuting the claims?
This is probably because people (i) were not aware that there had been many other hypes about RTSC before but less publicly visible all proved to be false, (ii) not being able to accurately judge the technical quality of the initial evidence, (iii) uncritically believing that the data in the initial preprints was proof for superconductivity because their authors said so.
While a convenient abstraction, it plays into our biases to notice and remember only some of the discourse.
Plus I don't think it's really relevant to what I'm saying given I'm not making a claim about how any specific individual or group reacted, but that it's odd when there's people who treat an optimistic outlook as an error.
