Even if you disable the 'AI overview', the search results themselves are powered by AI models as well. They have been since at least ~2018 with BERT.
Please comment in good faith. The discussion is about generative AI.
Maybe, but not necessarily. For example, I recently searched for someone who worked at a company using a plain language query. The AI identified one person (correctly, as it happens), but all the links below were to different people.
Obviously the results were not driven by the same AI that produced the summary.
No one's objecting to that aspect of things.
