See zeldman's 2006 article about when "web 2.0" turned into business speak. It was cringeworthy then.
Not sure why ppl think this is some new insight: Slashdot was "web 2.0" well before "web 1.0" was a thing. We had a reading group that went deeply into this after the publication of Kurzweil's "Age of Spritual Machines" (1999). AI is the baby of humanity, it will be trained on the web, blah-bitty blah blah.
Crypto and AI having nothing to do with the platforms or the delivery style/agents. IMO, "web 3.0" == "mixed reality 1.0", so I am biased
