The joke of looking symptoms up on WebMD and determining you have cancer has been around for... geez over 20 years now. Anti-vaccine sentiment mostly derived from Facebook. Google any symptom today and there are about 10 million Quora-esque websites of "doctors" answering questions. I'm not sure that funneling all of this into the singular UI of an AI interface is really better or worse or even all that different.

But I do agree that some focused and well funded public health bot would be ideal, although we'll need the WHO to do it, it's certainly not coming from the US any time soon.
