Ohhh. I have no real knowledge of electricity or electronics, but I know transistors are very fundamental so if you squint a bit, you might say this is what we set in motion when we program, or even just use a computer! Or at least some of it. Not knowing enough to benefit from it I learned nothing, and don't regret a second of that.
You can google for "From nand to tetris" or get the book Digital Design and Computer Architecture by Harris to get the idea of how these machines work.
