I wish I could separate decentralized database from volatile investment. I understand that it can provide an incentive to get paid for essentially hosting part of the database. Is your average person benefiting from this or did we just give most of the centralization to mining farms where electricity is cheaper? Is web3 crypto money? Is it peer to peer? Is it blockchain? Does the blockchain really make sense for something like a HN clone or an instagram? If I were trying to proselytize web3 I would be promoting tech demos and convincing people why it is better. Like the Rails blog video that blew all of our minds in the past. We all wanted to use Rails after that. The benefits were clear.
