Answer 1

A robotic cutter like a laser cutter can cut exactly the same shape out of a piece of steel for instance, every time. A human would never be this precise. Cutting a human open requires the same level of precision, not something you expect from a human to do thousands of times without smaller or bigger mistakes. You can expect a robot to be precise 100% of the time. Also the physical limit of precision when it comes to humans isn’t that high.
