I don't trust physicians or dentists opinions on this subject, because they have a vested interest in preventing technology from disrupting their field.
Its better to be the oracle with the Tea Leaves garnering the accompanying salaries and status.

You're right it's today. There's a bunch of HIPPA compliant, reasonably priced SaaS's available to do just this. Google it.
The obstacle lies in getting medical professionals to give their status, cush jobs, and money over to a machine for the betterment of patients and the field, which is going to be a hard won battle.
I for one can't wait until a nurse with good beside manner takes my samples and symptoms, sends them to a lab/records them in an EHR, and a machine with zettabytes of data and years of machine learning diagnosis me with more accuracy than a human ever could imagine.
