You are about right. Considering there is actually many jobs even higher paid than tech and programmers' jobs, then why this exact rational from TFA hasn't yet been applied to these jobs since the savings will be much greater? Many diagnostics and prescriptions from omnipraticians doctors could be replaced by automated systems with higher success rate and lower error rate in prescriptions and much lower price than the average or even expert doctor these days. These doctors essentially measure a small amount of physical characteristics, pulse, blood pressure, temperature and ask few questions to finally reach a diagnostic. This can be automated for the vast majority of common diseases. And when the application cannot reach a diagnostic because the case is too complex it could even ask for more information, blood analysis, CT-scan, bacteriological culture, etc. Which a nurse can take a sample as required of the tissus needed or the blood sample to be sent to a lab for analysis and the results being returned back to the automated system for further analysis. If at the end, the program cannot reach a diagnostic with a high probability, then the case can be refered to human doctors and probably to a panel of experts because at this point it is very likely the regular average doctor will not be able to do better.
