We like the idea of shaping stone knives, but we don’t like the idea of being stone knives ourselves. So the matrix variation of the old mammoth story goes something like this: “Mind imagines a robot; hand creates a robot; robot kills terrorists but also tries to control the mind; mind kills robot.” Yet this story is false. The problem is not that the mind will not be able to kill the robot. The problem is that the mind that imagined the robot in the first place was already the product of much earlier manipulations. Therefore killing the robot will not free us.
