Go program authors can beat their own inventions, so clearly this
depends on the problem domain. In the chess (and go) problem domains,
the time the human spends on the problem is artificially limited by
the rules of the game. For programming, limiting the programmer time
is a goal, not an axiom.

As an existence proof, unless you believe that the compiler produces
perfect code, dis-assembling (if needed) and hand-tuing the code
produced by the compiler should get you faster results than you
started with.
