So we’ve gone from the best semiconductor we can manage is -73 degrees C at huge pressures to we can do it past water boiling? This is a huge leap forward no?

resistance might be possibly zero above room temperature allowing for the design of superconducting circuits at room temperature
There must be some nuance here that requires some expertise to understand since I would think Tc up to 500K is way above room temperature but they’re being very cautious about saying they could build such circuits. Is that because circuit manufacturing is an even higher temperature process or something else?
This seems like a revolutionary result that’s the first step in changing everything we do in electronics from computers to travel. What’s the reason to contain excitement?
They're claiming to have found a small number of microscopic particles that are superconducting at 500K, with details on how they found those particles. They acknowledge that making contact with those particles to directly test their resistivity is particularly challenging. That is, even if this is true, there's a long road between the discovery of microscopic particles and mass manufacturing / large scale integration.
It would be quite inappropriate for them to brag about revolutionizing anything at this stage. The field recently witnessed that with overstated claims surrounding LK99. Much more appropriate to publish methods and allow other groups to verify or refute their findings.
They’re measuring particles they think are superconductive, but these are measured in micrometers. Optimism and measurement error are entirely possible.
If you could, for example, demonstrate flux pinning at room temperature on a sample of material weighing at least a gram, that would be exciting.
These first announcements aren’t exciting because they are far too possibly wrong. Good enough for funding the next study, not for getting folks on the internet excited.
