>The overwhelming majority of slow code isn't slow because it's failed to do this kind of microoptimization, it's slow because it used the wrong algorithm.
Try to look at The Computer Language Benchmarks Game where all implementations are using the same algorithm. An optimized C implementation can be 300 times faster than Python.
That's exactly the kind of missing the point that I'm talking about: tiny programs where all implementations are using the same algorithm and people have spent months microoptimising and are utterly unreflective of realistic business problems.
