AI Overviews are a good idea but the tech still needs to mature a lot more before we can give it to common folk. I'm shocked at how fast is has been rolled out just to "be first". Somehow, the AI Overviews also use Google's worst model.
The best thing about the AI overviews is it chooses better sources than you get from the search results, IE Google knows what websites are actually more informative and doesn't want to put them in the actual search results.
