I feel like Google used to be pretty great at answering questions until they started pushing ads more aggressively into their results, and then intentionally gimping their results (for instance if you put quotes around a word Google will happily ignore it, whereas this used to actually be an enforced rule).
I'm not sure AI is the solution to this problem at all. I think it's about misaligned incentives and trying to shoehorn a new cash cow into the mix.
