Can somebody explain to me the existential threat AI is posing to the search business?

I am familiar with ChatGPT composing reasonable sounding answers to prompts. I get that I could type in "what's the best vacuum cleaner under $500?" or something like that, and both Google and ChatGPT could generate an answer for me.

But I want the best, most accurate answer, not a set of banalities that a neural network has composed to convincingly pass the sniff test. I actually care about the content being right, or as close to right as possible.

I admit freely that I'm clearly missing some possibilities here. Can anyone fill me in?
