Problem with that logic is, humans don't just evolve genetically, we evolve culturally, and that cultural evolution ends up affecting our biology as well. So it doesn't really matter how slow genetic evolution is. Cultural evolution is what defines the human species. It's much more rapid because it includes planning and foresight, unlike the blind watchmaker of biological evolution. It is also lamarckian in that it incorporates the experiences of the previous generation into the cultural phenotype of the next one.

That's precisely how we've changed so drastically is an evolutionary blink of an eye.

And now, our cultural evolution has reached the point where we're even able to change our own genetics with planning and foresight in a single generation. So it seems to me that the blind watchmaker is essentially irrelevant now.
