Until Apple introduced iPhone nobody thought it was possible to make smartphone like that. Six years later many of us carry access to significant portion of human knowledge in our pockets. My hypothesis that at current technological level we can have full stack mining/refining/energy generation/assembly of new robots done by robots. Trick is putting right pieces together. Why is it not done yet? Not economically viable yet. It is far cheaper to design a simpler system with human controls, that assemble full stack robotic implementation.
