I keep thinking about how Google has implemented it. It sums up my broader feelings pretty well. They jammed this half-baked "AI" product into the very fucking top of their search results. I can't not see it there - its huge and takes up most of my phone's screen after the search, but I always have to scroll down past it because it is wrong, like, pretty often, or misses important details. Even if it sounds right, because I've had it be wrong before I have to just check the other links anyway. All it has succeed at doing in practice is make me scroll down further before I get to my results (not unlike their ads, I might add). Like, if that's "AI" it's no fucking wonder people avoid it.
At this point I'm pretty sure their strategy is to take the hit in search engine quality since they have a stranglehold there anyway, and spam everyone with AI so they can come out ahead on that front with Human feedback. It's pretty shitty, and the exact reason we would be taking down big tech monopolys.
