No, people superficially said the same things. Except if you know anything at all about the underlying tech, or about business, you immediately see the difference. This is why so many people disliked and totally ignored the blockchain hype (like me), but are very bought into AI (also like me).

One glaring example of the difference - you're making an analogy by saying that people were saying "get on board web3 or you'll be left behind". I'm not sure I heard people say it quite this way, but even if they did - what was the causal mechanism they claimed would "leave you behind" exactly? Why would the average user care? Not at all clear.

Whereas, correct or not, there's a very obvious reason to think adopting AI is critical - in SE, for example, it promises drastic changes to how people work and increases in productivity - it's pretty clear why not adopting it is a bad idea.
