Hello, this is my first post here, I'm not very passionate about physics, I'm a programmer but I have a little dilemma related to physics. I was talking with someone about nanotechnology and I said that we can create nanorobots in this way(theoretically): We create a "robot creator machine" that can also create a smaller version of it self. The smaller version of the "robot creator machine" will create a smaller version of itself and so on. We keep it up to a point we have a nanometric "robot creator machine". Then the robots the nanometric "robot creator machine" creates will also be nano. The person automatically refused the idea saying that this isn't possible not even in theory. I think theoretically(I must stress this) it is possible. What do you say?
