Well, for one thing it just makes you look ignorant and hypocritical to criticize AI when all search engines now employ it.

Think critically about AI Overview responses. Explore results from multiple sources to fact-check important info.
It might be practical to quickly double check one piece of information from an AI search summary that is usually just a sentence or two. It is totally impractical to check each and every source in thousands of words of AI text on this forum to find out which parts are being grossly misrepresented as invariably some of it is.
