When you say "people" I hope that you mean "minority of people". Yes, I've heard people saying that laptops will go away. Some people said that. Yes. Some people.
Web3 is just laughable. Again, some people.
Google is obviously not dead.
However, I think with AI, there's a huge potential. It will change the world, the way some things are done and some jobs are gonna go away and new jobs will appear. Much more disrupting than a f web3 joke.
