What about if the program takes a variety of inputs which influence the output? (At some point there has to be a transition, since e.g. books are "just" the output of some program.)
For any book, there exists some program which generates it, but most books are not created that way (so we consider those books to be products of human creativity).
I was talking about the word processor/text editor, since the things created by them are still just the output of some program (with heavy human influence along the way).
