This analogy doesn't work. There is a material difference between SO and Github and a machine that can talk to you and understand you. You may claim it doesn't understand you, then I can say, fine... a machine that perfectly and indistinguishably imitates a response made by an intelligent being that understands such that a difference cannot be measurably detected.
