timbl was ahead of his time. His concept of web3 meant including data in web pages. I played around with that stuff (RDF, FOAF etc), but it did not really take off. I don't know what his views are on crypto, but it does give us a degree of ownership that centralised platforms lack.
I can see AI assistants taking off. It's what we've been expecting computers to do for us for decades, but they are still pretty dumb.
