It Will Be Impossible To Change.

The fact is that gestural control by skilled humans for surgery by robots will come to pass quite soon, but then very quickly will get overtaken by robots controlling other robots, because robots will get vastly more knowledgeable than any humans (by several orders of magnitude), and with super-fine gestural control that will outstrip any human ever. Right now it’s not relevant because humans are still much better, but in a very short time (10–15 years) the opposite will be true, and the state of robots will finally become clear — and frightening. But by then it will be impossible to change.
