As Scott Huennekens indicated, this vision extends out 10, 20, and 30 years. And part of it is to make robotic surgery ubiquitous enough that it becomes much more affordable, and can be deployed into remote areas that currently don't have access to surgery at all. I don't know if it would ever get to the point of the robot doing patient prep, initial incision, etc., but if you were in a remote area and in need of life-saving surgery, would you allow a robot with a solid track record to do it, or just wait to die in a few weeks? To the autopilot analogy, if you are stranded on a remote island with no long-term means of survival and your only hope was some autonomous aerial craft, do you take the chance flying or stay put for sure death? I think the long term vision is fairly comprehensive for the planet and all its residents, but I am also quite confident that it will be an extremely profitable model long before it achieves that level of global saturation.
And maybe the two can tie in together! Autonomous aircraft delivering surgical robots to remote areas for life-saving surgery!
