web3 is that. Pay for content / services you use through micro transactions.
Web3 is things like json-ld and the like and it is tragic that scammers have been able to abuse the term for so long.
But together with other, similar technologies it extends the current with metadata etc web just like web2 extended the existing web with things like ajax interactions, drag and drop and folksonomies ("tags") and other forms of user generated content.
The (IMO) fake crypto peddler "web3" is (again IMO) "revolutionary" unlike web2 and the real web3: it is a complete break from many of the things that made the web great. I'd even hesitate to describe much of it as web at all.
Get your head out of your asses guys. There's nothing inherently bad about blockchain or decentralization.
