This is obviously a jab, but to answer the unspoken question: if it's still more effective than human doctors for black or female people, then yes it should be used. If it isn't, then don't use it for them. Simple as that. (fixing this problem should be a high priority either way, that goes without saying)
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.
