My question however is, why would i trust the "second opinion" of an online professional over that of a doctor WHO ACTUALLY EXAMINED ME in person?
Why would you Google search when you can visit the library? You know books are written by experts whereas websites can be published by anybody and are usually second opinion too.
Think of all the people in third world countries who might be able to eventually get easy access to the internet, but can't afford or don't have a nearby doctor.
Do not only think of the personal benefit but for the whole medical field. Sure nobody will trust a 'machine' over a human. But today, at least in my country, my doctor has to mail my personal records to another doctor if i'm changing my doc. Or the new doctor has to build the medical history for himself from ground up. This is due to privacy regulations but when I think of a blockchain with all my medical data, which I can maybe just export and bring it to my new doctor or even just share them with my doctor if he is also using eHealth First - this would be awesome. And, like I said, you could look up the blockchain for similar sickness and maybe find a better therapy which you did not know of yet. It has so much potential!
