Too Long; Didn't Read
The Internet will be a collective semantic engine driven by a shared language to describe entities and the way they connect and interact with one another.

The main actors in this space have built their own ecosystems, walled gardens and protocols, but there isn't much usable code on the Internet yet, nor usable specifications.
