google search results were true in that they accurately reflected the content of the pages that were found. it would then be up to me to decide if i trust those actual pages.
that trust level obviously varies, but for example if the page found is from wikipedia i know that the content has been reviewed by multiple people, so i can trust that more than say a blog post on the same topic.
on the other hand, AI results are not certain to be an accurate reflection of that wikipedia content, and therefore it is less useful than the page itself.
practically speaking i don't even look at the results in detail. i just check if my search keywords match and then i open the pages and read them myself.
the AI summary does not tell me which keywords on the pages matched. it is therefore completely useless.
