It was based on a legal fallacy and a technical one.
- The legal fallacy was that you own your health data, and can control it. That may be the law, but that's not the fact. The people who collect your data control it, and that control is important to them.
- The technical fallacy was that most people are versed on technical subjects, and either have the patience to input their own data or go through a complex download-transform process to get it.
Both these fallacies have been pushed for years by so-called privacy advocates, mostly shills of insurers, who use Fear, Uncertainty and Doubt (FUD) about technology to keep it out of doctors' offices. Through laws like HIPAA, and their continuing campaigns against reason, these "advocates" make it necessary for you to keep filling out the same damned forms -- over and over again -- whenever you see a new doctor.
