The problem I see with lots of software is that you don't have an immediate view of the scale. Suppose you're opening a random file. What do you see? Are those the atoms or the gears? You want to see the gears but there is usually no map to point you to the gears. The software is the map - yeah, right.

What are you supposed to do? Find the int main() and then make the program run in your head?

I can make an analogy with a car - I don't know every one piece of it but I can infer from the context. The scale is evident.
