gender-bending

So I heard today that for $20,000 you can choose the gender of your baby. The technique has been around for years, but now it's starting to become "affordable." It's kind of a creepy first step down a slippery slope. Eventually, are we going to get into Gattaca territory? Or more importantly, at what point are people going to be able to start breeding super-masculine women, or super-feminine men? Because maybe once humanity can get over the gender polarity hump, we might make some cultural progress...
