Particularly in more advanced applications of the Wolfram System, it may sometimes seem worthwhile to try to analyze internal algorithms in order to predict which way of doing a given computation will be the most efficient. And there are indeed occasionally major improvements that you will be able to make in specific computations as a result of such analyses. But most often the analyses will not be worthwhile. For the internals of the Wolfram System are quite complicated, and even given a basic description of the algorithm used for a particular purpose, it is usually extremely difficult to reach a reliable conclusion about how the detailed implementation of this algorithm will actually behave in particular circumstances.

Yeah, I find this article very insulting and condescending. "Don't worry your pretty little head, our ideas are far too complicated for you to understand!"
