While it is true, computing requires repetitive, continual retraining, I disagree about the parsing/logic/etc stuff. In class you're taught principles of X Y or Z and how they relate to Q V and R, or at least they do. When haphazardly picking up skills, you often do not come across the greater, abstract ideals, and instead see craftsman level heuristics to solve a problem. For your example, the parser thing, recognizing if you need an parser, a regular expression engine, or a simulator is a pretty heady, abstract thing for some cases. Very few people would ever educate themselves on the difference between the cases just to do so. But that difference is one of the ones a college trained CS grad should have.
