A program counter receives the same input pulse (the output of a clock - for synchronization) over and over, but works precisely -because- different outputs can flow from that interaction.Different clock values represent different states. You could also have used an interferometer.
But that's not the point. You've identified a lot of outputs that we as people would identify as important. But what's to say the sum total of a galaxy's interactions, with near-infinite complexity, leading to a supernova with a burst of photons heading off to an observer in a distant galaxy, isn't communicating the result of a simple binary gate: light = galaxy known to exist there, lack of light = galaxy not know to exist there? Or that even lacking an observer, those few photons' effect cascade via a Butterfly Effect to a major event in that distant galaxy?
Or at a smaller level, who's to say that the assimilation of a photon's energy into an electron isn't both a gate and a memory device: a gate, because it represents a boolean truth: that the photon bears the right quantum energy to be absorbed; and a memory device because that electron's energy level is sustained until a future interaction?
As a practical view of AI, I think your model works very well. However, as a philosophical expression of reality, it seems too anthropocentric and arbitrary. It's one thing for you to define a gate, but how would the mind-spawning universe define it?
