It seems it must be a tool in a tool chain, rather than a physician replacement. Tests must be run, and follow-up questions asked. Also, computers take everything literally, they don't say "Well, that's not what your face is telling me." or think the patient is lying, delusional, or misinformed. You can ask the patient on a scale of 1-10 of their certainty, but again, there are other problems.

"What are these red dots?" Also seems non-trivial to diagnose. They can be tested, or more questions can be asked of them, but this seems like an awful lot of work to be managed by a computer alone.

It's a good, or even great thing to research, but it seems far from implementation, and that's just from an engineering perspective, imagine the legislative hoops that will need to be leapt through!
