The original definition of Web 3.0 (or Semantic Web) was conceived by Tim Berners-Lee and meant something completely different, it referred to a web that had all information assembled into an open graph that was easily accessible and machine readable with the goal of leading to an AI revolution. AFAICT the "web3" moniker was co-opted by Ethereum developers to refer to something which is almost entirely opposed to that, it's about locking everything up on the internet behind paywalls. But somehow this is supposed to be revolutionary because technically anyone can set up a paywall, as if they somehow couldn't do that before, as if web businesses haven't been a thing since the early 90s.
