Never mind the almost unbearable cringe of incrementing a buzzword by not one, but two counts - do you have an explanation what exactly warrants this increment

Never mind the almost unbearable cringe of incrementing a buzzword by not one, but two counts - do you have an explanation what exactly warrants this increment at all? The only thing in there that I don't remember as "web3" are the decentralized web nodes, and I'm not really sure whether those are new either. Not trying to be sarcastic, I think topics like DID are important, especially as BigTech looks set to try to kill passwords.
