I used to be curious what Google's AI summary would say but found it to be wrong most of time for my searches so I don't expand it any more. I do not use any of the other AI and go out of my way to disable any form of it on every OS and application. In my opinion Google should dump its entire data-set, start over and work on better input filters.
