A program that can be very confidently wrong while giving people advice that can mess up their life
Literally WebMD.
I think there's an assumption that professionals are always correct. They are not. Professionals are also heavily trained to "[try] to make you happy and doesnt know if [they are] telling you right or wrong, only that [they] shouldnt say [they don't] know."
You're also neglecting how bad health care access, and legal etc., is. Especially in countries like the USA where access to healthcare is financially gated and increasing extraction makes "go[ing] to a professional" not possible unless you wait >6 months to go somewhere that's a >3hr commute from where you live. WebMD, Wikipedia and chatbots can help to decide whether the >$1,000 and 7hr professional consultation is worth it, and if so be more informed going in so that the time is better spent.
That being said, poor healthcare can absolutely have worse outcomes than no healthcare. I do believe that is a minority of situations, however I also lack any hard evidence to really back that up. Do you have any?
I thought the issue you had was with the information itself. Why does it "being a program" matter? That said, it is; "symptom checker" specifically and "page rank" more generally.
And? There seems to be this assumption that "wild West" == bad/dangerous/scary/harmful. The modern Internet is certainly far less of the "wild West" it used to be. I would also argue it is also far more dangerous, harmful and nefarious than the "wild West" web.
Anecdotes aren't useless, but they need to be contextualized. Is it higher than the baseline? Is it greater then those who didn't commit suicide because when the mental health institutions failed them they at least had some sort of backup?
Navigating healthcare while dealing with a mental health issues is a paradox. Is the damage caused greater than the damage prevented from allowing access to a tool that can help lower that barrier to entry?
Looking at general trends I find that the harms outweighing the benefits very hard to believe. Do you have anything non-anecdotal, on that specific point, to back it up?
