I understand all that but, jelly fish have nerve bundles, not brains. Even a brain is nothing more than a collection of cells that transmit electrical impulses. Using chemically created electrical currents transferred to other cells that are all exactly alike. There is an experimental line of robots made by Mike Tilden. The "brain" is based on a neural network, there's no computer. They are solar powered and he claims they actually seek light to keep charged up. The idea is, if you created an artificial brain, attached cameras for eyes, microphones for ears and etc, could it learn? Could it walk, talk, think, respond, obey and all that?
