You are a hydraulic system. You are composed of interlinked pipes within which the pressure rises and lowers in order to produce all your thoughts and actions.

You are a chemical soup. Your body is a closed system of proteins and amino acids reacting with each other, driving behavior in order to sustain the reactions.

You are an electric grid. A system of interconnected wires where electric impulses respond to one another in a synchronized manner, from which your life force is derived.

And if you're Steven Wolfram all of those are just automata as well.
