    @JohnDCook: Hi John! I've updated the description to reflect this. Congratulations! This is great news for companies who will no doubt benefit from your excellent programming skills, broad knowledge of mathematical computation, statistics, modeling, etc..

    Right on!

    R is a great example of code in which performance is not a critical problem.
    If somebody would like to calculate a variance of some given data it really doesn't matter if it takes 0.01 seconds or 0.001 seconds. For typical datasets it is acceptable.

    In long run it is better optimize everything at the machine code level but today it is time-consuming and because of that it is too expensive.
    It is much faster (and because of that cheaper) to write the modeling code in R instead of rewriting everything in the machine code (which is a very slow and complicated process and because of that very expensive).
