I know so many people who've just done basic CRUD business programming. Smart people, really smart people, but they limit themselves; don't try to do anything deep and interesting, and it's sad.
I don't know much about CRUD business programming, but I do know in every field there are many levels of difficulties. Maybe these smart people are trying to solve those problems? If a system has simple atomic parts, it does not mean that every problem will be easy.
Edit: "Specialization is for Insects.", wow if you believe that, why do you live in an society. If you know every general thing, then you must be able to make your meal right? It will include farming, harvesting, cleaning of wheat, making your own bread (with equipments that you make on your own) and then slicing it and serving it. And that is just bread ;)
