Fair points - I don't believe that Apple / Samsung are necessarily going to build out their own EMR systems. Rather I think the bottom up approach they are taking by creating an enormous amount of personal health data -- heart rate and exercise activity now with a growing ecosystem of third party devices -- that is up to FHIR specs is a step in the right direction.

Your second point really resonates with me. I have spent the last few months working within a large healthcare organization and it is extremely difficult to make necessary changes. There is a lot of distrust of our team to the point of hostility. Very frustrating
