> I read through this thread and I can't help to feel reminded of the discussion about cryptocurrencies.

Same. Some people are simply wired to be perma-skeptics / perma-bears / perma-negative. This community is still full of people who truly don’t grasp how world changing bitcoin is. They are in complete denial, most often parroting unoriginal talking points that they’ve been handed from others.

It’s easier to bypass deep thinking and deep learning and just imitate being an expert. It takes courage to admit being ignorant.

I’ll be the first to admit that I’m not an expert in superconductors. I doubt most people in this thread are. But they are parroting and making ignorant predictions - just like crypto.
