I rarely use Google for search, but I've actually gone back a few times just to use the AI search function. Occasionally it is useful, especially when I can't think of the correct term to search for.

But recently I had an entertaining experience with it. I was trying to apply a math technique to an application it wasn't normally used for, and I figured that somewhere out there was a paper or two explaining how to do what I was attempting. So, I tried Googling, and the response was something like:

"You appear to be working with two completely different areas of mathematics, which have absolutely no connections between them. That's fascinating! Would you like to know more about either of these two completely separated subjects which have nothing to do with each other?"

Not useful, Google, but definitely good for a laugh.

I read it because it's shown before search results now but I have to stop myself to not accidentally rely on it. Had two times it misinformed me pretty blatantly and its links to sources are wrong a lot.
