The primary reason why there wasn't much automation in the past was the combination of doctors being conservative (which is a good thing) and lack of competition among established medical companies (the ones conservative doctors depend on). You can see how the two couple stifling innovation not through any conspiracy but just preferences.
Both of those aspects are being relaxed today. Doctors are become tech-oriented and more diagnostic companies (run by first-rate medical/engineering teams) are starting up that may upend more established medical companies. We will see a rapid change in the diagnostics landscape in the next decade. This may also add some risk to the diagnostic field, but the benefits far outweigh the risks.
