Let's generalize the question. Why are our brains able to engineer machines that produce forces greater than a human body? Because they understand the forces, and set them into motion with tiny efforts to build mechanisms that eventually unleash and reform large amounts of energy, creating the force. And what if intelligence is another kind of force that can be created by taking tiny, human efforts, building a machine, then pumping huge amounts of energy into it, outputting the intelligent force? Or let's consider evolution. How could it create intelligent brains from single celled organisms? Incrementally, as the organisms randomly accumulated mechanisms of adaptability and eventually sensing and cognition. In the first view we see ourselves as engineers, building a vast engine that, through its sheer size and energy, and our basic understanding of fundamental laws of intelligence , produces an intelligent force greater than a human mind. In the second view, we see ourselves as blind watchmakers, jamming AI components together at random, until, by accident, we get something smarter.
