Jeez— it's almost like few people around here are physicists, consider physicists credible on their specialty, saw physicists excited by the potential, and get excited by exciting things. What a shamefully foolish intellectual failure!
As noted by the sibling comment, the physicists (especially those who specialized in superconductor research!) were the ones who were the most skeptical of the announcement, partially because claims of room-temperature superconductors are actually relatively common, and partially because the evidence in the paper was just atrociously bad [1]. One of the things I look forward to in an HN discussion is the comments of…
HN is full of subject matter experts on computing-- that is, software, and to a lesser extent, hardware-- beyond that it's a mixed bag at best. Even as an interface designer, I see so much confidently presented and totally bogus pseudo-expertise on art and design here that it's actually kind of funny, and that's much more closely related to software development than physics is. That BS sounds credible to other developers because it's in a developer's voice and trips on misconceptions common among developers. I suspect that's true with the other non-computing topics discussed here that I don't know enough about to give an expert opinion on.
As a long-time developer myself, I've been on both sides of assuming our astonishing intelligence and analytical capability can make up for lacking the requisite expertise. The mistake is expecting the HN crowd's musings about things outside of it's expertise to be more trustworthy than any other internet forum. If this were some physics subreddit or something like that, the criticism would make more sense. This is just people being excited by something a lot of other people were excited by.
