If you stop labeling things neuron and just call them imperative code, or a PID controller are, you still making the same argument for intelligence?

A line follower with 5 photodiodes and a simple loop steering towards bright or dark lines (pid or not) works, just like the example of following light with two neurons.

When I did hobby robotics competition, some would train neural nets for this, many just had crude for loops, and most often it was PID.
