A ways back, the president at a multi-discipline engineering consulting firm I worked in made an interesting point. If you give ten EEs a hardware task, they will come back with something that looks similar. If you give ten software engineers a software task, they will come back with ten completely different things. I think this is because in software there are so many possible ways to do something, and so much richness, that writing software is a very different from making hardware, or architecting a building, to go along with the parent comment.
