I disagree. My experience is that excellent programmers become fanbois because of their frustration working with sub-standard tools. So when they find the tools (by which I mean language) that allows them express their craft in the best way possible (for them), they latch onto it and become fanbois. All of the great programmer's I know (small sample I guess) have a favourite language, and generally dislike working in other languages, even though they can.
