When I was an EE major I distinctly remember designing an APU and thinking what a convoluted cluster f* the whole thing was -- taking electron flows, pouring then over specific transistor arrangements (transistors are not binary, they are amplifiers) that take time to flow over a transitor set for each binary digit, and design it so it had the right answer at the exact time of the next clock pulse. I wanted to just take two signals and let them superimpose and let nature to the instant addition. Of course the "context" between the analog and electron stram with a clock "digital" just wasn't possible on the process of the day. Or today. Maybe someday in all optical computing. Or something else...
