When having these discussions (and the inevitable anthropomorphisms of nature and evolution), it's important to view Past Evolution and Present Evolution as distinct.

Past Evolution is a billion-year-old algorithm from which emerged deep and subtle intelligence through trillions of trillions of iterations of trial and error. Though far from perfect, its legacy is the Terran Ecosystem, aka Mother Nature + Humans, a force to be reckoned with.

Present Evolution, however, is lazy, cruel and sloppy. On the scale of mere decades, it does effectively nothing to advance the interests of human life.

(Future Evolution is of course significant, though not on a timescale relevant to our lifetimes, at least if we're referring to the "untampered" variety.)

I view genetic augmentation as inevitable, leading to an accelerated evolutionary process; however, I can see valid cases for either throwing on the brakes and going as slowly as possible, or putting on the gas to maximize progress, with all its benefits and costs.
