Did you mean this is Web 3.0? (semantic web)
Where the goal was to have a site's data as machine readable so that could be mashed up into something new? Instead of making it easier to gather the big sites locked the bulk of their data down so it never gained widespread adoption
Web 2.0 is what we mostly have now -- social, user generated content and interaction
Unfortunately (?) there are no real semantics in MCP so it falls short of Semantic Web.
I think 3.0 as a term was taken over by those weird crypto guys with their alternative dns roots and suffixes, that literally no one uses. “Own your domain forever!!*”
* Disclaimer: domain not usable for any purposes except on computers where you have root to install their alternative resolver
