Realization About City Planning

Imagine a really bad piece of code. Not just little stupid things (like 'if (x == true) return true; else return false;'), but big design problems that prevent it from being changed to work in the ways that you need it to work now, that has a tangled web of dependencies and versioning and redundancy problems, and that is arcane and fragile and different parts are built on totally different infrastructures. Thin facades protect you, but you know that underneath be dragons.

Now, picture that... in concrete.

Ouch. Now I feel sorry for city planners. My discovery of how much work it is when the program managers want all my components to work differently must be nothing compared to, say, realizing your city needs to support mass transit.
