Robots as in any other mass production process, the intention is not to be better than humans is to be consistent to the maximum possible time and repetitions, can a surgeon be better? For sure 5 to 10 times probably. Can a surgeon be better when performing in 100 patients? There is no way. This is where robots will help to improve the life of a patient, they are millions of people who can't never be able to access a spine, knees or many other standard surgeries not even because of money is just the volume of surgeries, if a robot tool can help a doctor to perform 100 patients at the average that he can do it in 5 to 10 patients, thats it, is working and it should be enforced as a standard practice, maximize the doctor skills that's the initial approach.
