> If you make code anything more complex than that then it isn't really equivalent to navigating the streets on a map. My point is, you should strive to make coding not more complex than that, if possible. And if you have constraints such as must represent the program as a 2-D dataflow structure then it must stay simple as that. Now is there a need to make more complicated programs? Probably yes. But human society is still able to function with the simple dataflows that it has, which makes it understandable and thus very resilient.
