Author seems very smart, and has probably done some good consciousness work to show up with these ideas... but this is completely ungrounded & disconnected from any real use case & understanding of market dynamics... much like the rest of Web3.
This is (I think) supposed to be a shared language between note-taking apps (and eventually others that include "thoughts" I presume). The hopes are that it does "affect everybody," but it is not something that can "affect everybody" without "apps" speaking in this shared language.
If you are not somebody who works on these kinds of things, then yea, probably useless to you for now. I think the author wants interoperability at the "thought" level between apps that support users inputting their ideas.
