cause and effect system every action requires energy and there is limited storage capability that each machine has due to power density hence the need to eat 3 meals a day, as for doing work the human machine is slow because it processes information at a slow speed that's why it takes so long to do anything, as for gaining knowledge the brain requires learning, and feedback is slow because of how our brain work there stuck in the slow lane, as for AI it will inherit all human knowledge built directly into its mind without ever having to learn anything
