I disagree. Most universities have, for example, both a chemistry department and a chemical engineering department. They are different (but related) disciplines, but both belong at the university.

In the same way, I think we need both "computer science" and "software engineering" - but they need to be different departments. They both belong at the university, though. (I'm not sure you go to a polytechnic school to learn chemical engineering.) The problem is, most universities try to teach a computer science degree to people who will work as software engineers (and therefore don't teach them as much software engineering as they should).
