Yeah, and IMO it's not even a good theoretical way to look at an analog computer. The hard part that will eat up time is differentiating the small differences

Yeah, and IMO it's not even a good theoretical way to look at an analog computer. The hard part that will eat up time is differentiating the small differences between spaghetti to arbitrary precision. Analog systems still have to deal with signal to noise ratio issues, which affects the decision criteria here as in, "which one of these is the next longest?".
