Engineer's Disease refers to specialists in one field assuming that they can speak with authority some other unrelated field. Healthcare in the US is notoriously complex and complicated, it would be naive to assume Amazon's success in distribution, ecommerce, and cloud services would necessarily translate to health care.
Complex and complicated is an understatement. It's a complete mess with a lot of very greedy unscrupulous people involved.
A lot of times the "care" people get is really crappy also, in spite of expensive insurance. Oh, but they'll be sure to offer you a $30 orange juice. Then you'll be getting bills for months/years afterwords and not be completely sure what they are for.
I realize medicine is a specialty. I realize it takes a lot of training to be a doctor. But I've always believed that a lot of what medicine solves isn't unknowably esoteric. A lot of it can be solved by a person with some hands on experience and good observational powers and base knowledge (not brain surgery obviously but things like yeast infections, simple broken bones, etc.).
The whole thing really is more ripe for disruption than any other area I can think of.
People have been pursuing "low hanging fruit in the digital health space" for the last 5 years with little to show for it. Most successful (as measured by acquisitions / adoption in the broader industry, not by VC funding raised) health IT startups come from "flyover" states and are created by people with tons of domain expertise and enough engineering chops to execute, not the other way around
