Opinion: Do we need doctors or algorithms?

I was asked about a year ago at a talk about energy what I was doing about the other large social problems, namely healthcare and education. Surprised, I flippantly responded that the best solution was to get rid of doctors and teachers and let your computers do the work, 24/7 and with consistent quality. The beginnings of "Doctor Algorithm" or Dr. A for short, most likely (and that does not mean "certainly" or "maybe") will be much criticized. But Dr A. will get better and better and will go from providing "bionic assistance" to second opinions to assisting doctors to providing first opinions and as referral computers to the best 20% of the human breed doctors.
