I don't think the idea was that reading the article would change how you thought about coding. I believe the point was that trying out these unusual programming paradigms would change how you thought. For the cases on his list that I have tried (declarative programming and Forth/Joy) I have found that to be true.
I would add object oriented programming (eg: smalltalk), macro programming (eg: lisp) and functional programming (eg: Haskell) to the list of things that change your thinking, but since most of the article's prospective audience has already heard of those I was happy that he stuck with paradigms that are LESS well known.
