I don't think web2 is going away any time sooner, but rather some kind of fusion is going to happen that will take advantage of web3 decentralization and web2 exposure to the masses. Think about PayPal's stablecoin or YouTube adopting InLeo features. Even better some clever 16 year old kid in a year or two will come up with an idea of decentralized AI super app or something we can't even realized yet it's possible to do. Some will recognize the disruption, many won't - but hey that's the charm of change :)
