I hope the following provides some insight as to the automated versus human debate here:
There's a similar revolution going on in science - perhaps one that is more mature than the one in medicine. In organic chemistry, the utility of the organic chemist is hotly debated now - should chemists go into that field, since high-throughput machines have been created that can do essentially the work of 10 graduate organic chemistry students? I believe it was a Science paper that revealed this really amazing machine. Basically, the machine can weigh and mix in reagents, add the solvent, and quench the reaction whenever you want. And since it's fully automated, it can make precise measurements and so you can scale down your reaction so that you can do it in a 96-well plate and boom, you're in business. Now, you can run 96 reactions in a day using any permutation of reagents and solvent you want for a given reaction and screen for optimal conditions very quickly. (You'll be hard-pressed to find a graduate student who can set up and process 96 reactions a day).
So with all of this technology, what role does an organic chemist have? I believe that these new-fangled devices can be tools for the synthetic organic chemist instead of replacements. There are several reasons for this. Machines need guidance. You have to tell the machine what to look for and that takes expertise. If I want to do a C-H activation reaction, I have to start with reagents that are known to functionalize C-H bonds. I can't just mix in every reagent ever created. That takes insight and expertise. Machines also may take longer to find the solution. This is because machines can only do the laws of statistics and probability to do what they are programmed to do. As such, if you're looking for a path from A to C, the machine will necessarily apply a combinatorial approach to finding that path, testing various paths from A to C. But humans may have insightful shortcuts. You may already know from experience that passing through B makes the trip shorter. So you can tell the machine to compute only paths that go through B. Now you've drastically reduced the computational power needed by reducing the sample space.
Applied to medicine, this implies that physicians will be the benefactors of these new tools because they will enable them to perform at a much higher level. In contrast to replacing physicians, these machines will actually help physicians accomplish many more feats - scientifically and otherwise. Think of it as the PCR machine. Before the automated system, graduate students had to sit there and manually go through the PCR cycles. Think about the opportunity cost lost there. What else could they have been doing with that time devoted to menial labor? Physicians will always provide the expertise required to guide these machines and derive maximum benefit from them.
