Right¹, the interesting thing is not how fast I can get with N times the
effort, but if I can get fast enough with 1/N.

Many of those people are making fairly simple mistakes.  I think a
somewhat seasoned programmer using good libraries can write declarative,
concise, and readable code that still is reasonably fast.

-k

¹) At least for some approximation of the word. Only one benchmark on
the shootout has C at a 3x advantage.
