“This context” is a hard problem because we need an ontology of contexts. And ontology is a hard problem because we need SOMEONE to be in charge of the ontology, like a World Wide Web Consortium (w3c) committee of experts perhaps, but we simultaneously need NO ONE to be in charge of the ontology, bc the last thing we want is subservience to another goddamn committee of experts. What we need is a decentralized language, like the spoken word, but digital. **This is the hard problem.** And almost a decade of thinking about it is how I’ve come up with the tapestry protocol, i.e. the concept graph and the grapevine.
