These "robot surgeons" are still driven by humans, but can be done remote. That means no need for surgeons in many remote locations, and no need for patients to travel long distances to get specialised surgery. It also means one surgeon can operate on a wider array of people than just their local area. Again, it doesn't replace a human. But it means fewer are needed to treat more people. This video demos a grape inside a glass jar, similar to human keyhole surgery. The robot-assisted surgery here is peeling the skin off the grape, then suturing it back on. How the surgeon controls the robot. Many of these have fairly accurate stereoscopic displays to give the surgeon a proper sense of depth.
