I have to say I don't quite understand those saying that "It is an abomination to mess with genetics" or "Once we start messing with genetics, we're playing god."
Man has been "messing with genetics" for years. Have you ever seen a chihuahua, a golden retriever or a poodle in the wild? No, because these animals do not exist in nature. They were bred over thousands of years to intentionally pass on the most desirable genes and create creatures tailored to the positions that man needed them to fill (herder, hunter, gatherer, worker, friend).
Just because it wasn't done using a centrifuge and a pipette, doesn't mean it's any different.
