How much time does dispatching take? It seems that dispatching is an expensive process - especially just for the ability to override/substitute methods at runtime and create dynamic hierarchies, etc.

I'm still learning objc/etc, so maybe I'm missing something - or I'll wait until you dig into the object runtime in the next article?
