Web3 was about decentralised web - as in, more stuff, like login and data, moving client-side. E.g. instead of having "login in facebook", having Metamask plugin in your browser, that holds your private keys, and allows you to log into a website. Also, building websites that don't store user data at all. Everything is kept in browser storage. You could say that the chat-gpt interfaces people are building now are web3, because they don't store your api keys, nor your converstation history. Second part was decentralising as much as possible. Decentralised domain-name systems (ENS), storage, hosting, and money of course. So that you own your data, and your identity. The last time I checked, the decentralised storage and hosting were the most difficult to solve. That is - we have torrents of course, but if you wanted to pay decentralised web to host and run your scripts indefinitely, it was not feasible.
