If the original article doesn't understand evolutionary optimization,
then it's a peer review failure.

Mutation is not selection (though not entirely blind, once the
system has evolved evolvability), all the selection is done by
the fitness function -- which is not static, but certainly selective.

Yet that mess produced you. Using pretty pedestrian means.
That's pretty damn powerful.
And strangely, the very thoughts you're forming right now are
produced by a highly similar process, by selecting competing
activity patterns in your neocortex.
Those who don't understand evolutionary optimization are doomed
to reinvent it, poorly.
