I feel like some dinosaur trying to manually think up every line of code to understand how this would look in some kind of Basic, because that's what makes most sense to me. Things then made sense because one transistor = one transistor function = one logical gate. Then you represent that gate, which in physical terms is what he said there, but it's either 5 volts or negative 5 volts, and then current is let through. So it's like you're changing the voltage threshold on a transistor, and then sending an adaptive voltage into the circuit which is made up of layers of transistors. Now I'm aware that logical gates aren't actually based on transistors originally, the Boolean functions are logical theory, but I can't seem to get past this easily when they keep representing it saying they are built to represent a brain, but with transistors, then making it into code.
