They are related to the discipline being quite new, I think.I have seen little correlation between studying computer science and being able to program well. That might also have something to do with the generally atrocious quality of CS teaching in Germany. Professors try so hard to avoid "dirty practice" in favor of doing quasi-mathematics that they ignore interesting and fruitful fields because (get this!) not only does practice follow theory, but vice versa as well, maybe even more so.
