I thought that this was a relatively good article in that it explores a number of features of web3 that go unmentioned by others (and critics especially). But I think we need to be clear that we can talk about web3 without talking about crypto-currencies (like bitcoin or ethereum), just as we could talk about web2 without talking about PayPal or advertising. 'Play to earn' models and NFTs are the web3 equivalents of affiliate marketing and commercial e-textbooks. The web2 or web3 model makes them possible, but it doesn't make them necessary. But it is true that while "web2 is about communication and sharing (like Instagram and Facebook), web3 is about creation and ownership where users can retain control."
