Same thing with doctors.
Why not ? A bit of glue (or duct tape) should help anybody. /s
2. Even some ideal frontier model is only as accurate as the inputs given for diagnosis, and will typically bias towards said inputs.
3. Multi-modal can handle images but are terrible at image classification unless using dedicated models for each pathology.
4. The very large majority of traning corpus with these companies is in English. There is zero guarantee that said mythical performance is preserved across languages.
5. The very thought of companies with the moral compass of most AI companies accessing and training on your medical records should make anyone pause.
I don't claim to know whether that could be done feasibly for medicine, I only point out that medicine is uncommon in how it educates.
Which, coincidentally, won't be solved by AI anytime soon. You'd need a full anthropomorphic robot (it needs to look human for a lot of people to interact with it on a sufficient level), and the ability to distinguish bias from experience from prejudice. (A lot of humans suck at that as well, to be fair.)
Any medical AI at this level will only be as good as the human medical professional using it, and it will make preexistent human-caused bias/prejudice problems much worse.
(Largest one I'm aware of: not being male is an appallingly large handicap to getting properly and correctly diagnosed, even in Western countries.)
