It's not only mentally ill people that are at risk, but anyone that doesn't know it's not a good idea to put "non-toxic" glue in pizza cheese. That includes a lot of not-mentally-ill but just plain dumb people. Google didn't need to tell people that glue+pizza is a reasonable thing to do, or even just a thing. It sure did frame it like it was a legitimate response. And Google didn't even have to reply with this or anything else, they could have just supplied the links to other sites where it had been suggested, but no - they have to make a show of force with their premature foray into AI, and have it tell real people all kinds of false, and possibly dangerous things. That's an unforced error by Google that they could end up being prosecuted for.
