One thing though, the internet was/is solid technology. Underneath the internet bubble was something that worked. Blockchain is promising technology but without solving the scaling issue it will always be just that.
I expect that the problem won't be solved, and instead we'll get a formal proof that you can't build a fully decentralized, trustless system without Proof of Work, at which point I hope Bitcoin & others will get labeled for what they are: crimes against climate and sustainable energy economy.
