Like many discussions, this seems to demonstrate that a Programmer != a Developer != an Engineer != an Architect. Of course, many programmers would never need this stuff and many have no formal qualifications but they still produce what they need to without problems. They certainly do not need to know about paradigms vs concepts vs models etc. even if it is interesting. Of course, there ARE people who need to know this stuff to do their job well but they are quite up the food chain compared to most of us. They might also be corporate, who of us sits down and thinks, shall I do this in OO or functional? Which paradigm fits? Most of us know few languages and use what we know.
