AI can be a serious helping hand when trying to figure out what diseases you have.
Not everybody has access to doctors, sometimes, whole countries don't have good specialists in everything.
When Google refuses to answer medical questions (when it could have answered and said "be careful, I'm not really sure"), it's actually putting lives in danger by hiding useful information.
If you can, of course it's better to go to a triple Nobel Prize doctor that is 200 USD per session, but not everybody can, and these doctors may not even be available in your country.
But otherwise in general, it's better to have the opinion of AI than nothing.
In the mean time these problems should be surfaced and corrected.
