Vitalik is a clearly a smart guy but I don't get this "All solvable problems" mindset of him and others. Saying stuff like "supply chain apps" is a key application at the same time global supply chain apps on the blockchain are getting shutdown. The only use case of blockchain is coins and those are merely unregulated pump-and-dump. Bitcoin was an interesting thought experiment but the probably is that you need it to be profitable for individual miners (minus pools) to drive true decentralization and as soon as that is true, economies of scale will win and there will be a drive to centralization.
