Just like any medium, if you take the time to become familiar with the tools you'll find that the tools become an extension of your body and become part of the art as well. It's useless to criticize the fact that the computer is part of the creative process. Anytime you create a piece of art the tools you use become part of the creative process. That isn't a bad thing. For a painter to complain that paint stops him from doing his best painting would be absurd.
Contemporary art is the result of the strong development of techniques.
With today's technology a mechanic reproduction of images is possible. As I stated in my previous answer I feel that to create your best work you need to be comfortable with the medium. But again this isn't anything new or anything to be disputed. The development of new tools will always influence an artists work. Oh that's a hard one.
