The people who are advocating web3 are not the people who were part of building web1 & web2 (whatever those even mean). They're people who are idealistic & seem to disregard (or are ignorant of) the effort in building infrastructure at scale. Building things is hard. Building things that scale even harder & anybody who has worked at a company that needs to scale knows there are trade-offs between security, centralisation, reliability & making things work for the user in a nice way. Web3 is a moot point until somebody actually brings something real to the party. Otherwise, IMO, it's a hype train.

EDIT: Ironically, web3 also seems to be able to rip the environment a new one. Which is pretty funny given the demographic of its fans.
