>So be careful about confusing simplicity with triviality and thinking that something can't be important unless it's complicated and deeply mathematical.

That's true of most things in CS, I think. Maybe life in general. I'm educated in cybernetics, and our most advanced stuff is hardly ever used. Too costly to implement, tune and test, very few areas where it's truly necessary. PID will work well enough for your application 99 times out of 100. Model Predictive Control is very cool, but it's going to cost you a lot. In places that need advanced regulation but where strict guarantees are not needed a properly trained ANN will beat a more analytical approach and require way less education to pull off.
