It's shocking to see how bad they've become at what used to be their core function. I mean their brand name became the verb for looking something up on the internet. Now it just returns a useless mix of advertising, blogspam, AI spam, and sometimes-useful reddit results.
I'm also not quite happy with the search experience due to them constantly moving UI components around randomly. First they started shuffling around the order of the search tabs (All, Images, Videos, Shopping, News) erratically, and now they've also decided to also start including what they believe may be related search terms there as well, sometimes.
