As a consumer I actually quite like the current Google search. The AI thing often tells you want straight away and usually links to sources if you want to fact check. The traditional link thing works too. The people who say it's unusable usually can't give an actual example of something specific it's been unable to find. I've come across a couple or areas where it struggles - old obscure stuff where I think most engines have limits, and piracy stuff for which you can use Yandex.
