One of the interesting things about crypto to me, is that the projects that don't involve pollution, speculation, theft and crime don't get noticed because of the lack of controversy or speculation.
People are like "but what if there wasn't artificial scarcity", well those projects exist, they just fail to coordinate humans to care. What you see is survivorship bias. There are many onchain-only versions of other onchain projects without any token at all! Annnnd thats exactly why nobody knows about them. (some are pretty active though, they just don't bubble up and out to a broader community)
Theft and crime? I mean if that's the headlines you see, (or even if its your actual experience), thats still not nearly everything.
Pollution? Proof of work still taking up all the headlines when only like 2 out of like a thousand blockchains are heavy on that, with one of those 2 trying as hard as it can to go off of that.
(I'm not opining about the "revolutionize" part, that one is so subjective that its not worth bothering.)
