* Alternatives to patient-present doctor-mediated health care to cover the 80% case in which doctors are expensive overkill; some combination of telemedicine and nurse-practitioners.<p>Doctor salary only makes up ~8.6% of overall Healthcare spending.  Since, right or wrong, people <i>want</i> to see doctors rather than nurses when they bother to go into the hospital in person, I predict this tech will actually <i>increase</i> healthcare spending.  The main change will just be that people seek nurse advice from home for minor issues they would have ignored previously.  That may more may not be a net benefit.
