To a certain degree, this is true. However, a profiler won't turn the DFT into the FFT.

  The FFT only needs to be invented and optimized once, though, then everyone else can just link in libfftw or kissfft. All those software tradespeople can do the jobs that require connecting pieces together. A tradesperson can be taught enough to know which algorithms to apply in which situations. Computer scientists become academics inventing new algorithms, and analyzing and perfecting the ad hoc algorithms created by software tradespeople. Aside: I wish the English language would just decide that "man" and "men", when used as part of a compound word like "tradesman", is gender neutral.

A tradesperson can be taught enough to know which algorithms to apply in which situations. Is that a circular argument? If we had enough people cranking out smart enough algorithms (like the automatic programming example upthread), would we need so many tradespeople?
