Most people Google things they're unfamiliar with, and whatever the AI Overview generates will seem reasonable to someone who doesn't know better. But they are wrong a lot.
It's not just the occasional major miss, like this submission's example, or the recommendation to put glue on a pizza. I highly recommend Googling a few specific topics you know well. Read each overview entirely and see how many often it gets something wrong. For me, only 1 of 5 overviews didn't have at least 1 significant error. The plural of "anecdote" is not "data," but it was enough for me to install a Firefox extension that blocks them.
