I still see more crypto/blockchain adoration here than disdain, although the tables might be turning slowly now.
HN users are much like magpies: once an idea shoots up, you can't swing a cat without hitting a zealot. If you are ambivalent or skeptic, you'll be furiously explained into the corner. Then, when the fad fizzes out and its inevitable drawbacks are publicized by more and more sources, the "told you so" camp starts merrily chasing the dwindling numbers of zealots around, while some former zealots get depressed from their high hopes being squandered and the resulting dopamine deficiency.
A new shiny comes in (say, "rewrite everything in Rust"), the cycle repeats.
You say "web3/blockchain", I hear "homeopathy", "astrology", and "bioenergetic therapy". The HN crowd might be fad-gullible, but stupid-gullible? I don't think so.
