I’ve had many situations where a sourced AI summary has references that don’t show up in the top search results. Clicking through to the source gives me the nuance and context of the full post that I wouldn’t have found without the AI summary. Even if you don’t trust the summary, rightfully so, it can still be good at surfacing good results.

(My experience here was with Kagi, I’m not sure how Google and others are with this)
