As a healthcare provider (albeit paramedic), I don't think the issue is AI's encyclopedic knowledge of disease, but rather, how to draw out a good, structured patient interview and exam, and cross-reference details. I could regale you with patients who only remembered their serious penicillin allergy when we got to the hospital, or forget their shoulder pain when describing chest pressure and so on and so on and so on.

However, this is something an AI can be good at. And well, GIGO, be your provider human or AI. I can't act on things you don't tell me. Well, somewhat - if I'm looking at your lower legs and seeing severe edema, I might be skeptical of your claim that "other than what's going on today, perfectly healthy". So maybe we need realtime video too.

Relatedly, I was talking to my immigration attorney, who has been very good, on an area where immigration law intersects some other topics, and she was fairly obviously using AI on our video call to guide her on many areas she wasn't as familiar with.
