You had the knowledge to discern whether the info given to you was legitimate. The average user doesn't have that. What if I need to look into something that I have zero knowledge about? When I get a list of sources, I can look through those sources and at least partially determine whether they're reliable. If an AI just spits an answer out, do I always just trust it?
Search engines are getting bad enough about throwing crap information at me. I think AI will just increase that. I prefer that I have the power to sift through the sources. I'm not willing to hand that completely off to AI.
