“The dystopic view would be IVF clinics that offer parents a menu of options for kids,” she says. “Nobody has kids by sex anymore. You go to a clinic, pick from a menu, say, ‘I want my kid to be this tall, have this colour of eye, this level of IQ,’ and all those sorts of things. I think that would be terrible.” - Doudna

It may be unpalatable to our sensibilities now, but this is actually the most likely scenario for how our species as we now know it will cease to exist. I have no doubt that we will upgrade ourselves into other species. There will be conflict over it, but attempting to ban this will never work. The technology exists NOW, how much longer do you think it will take for the will to be there? I'd give it less than 10 years for the first baby, and 5 generations to have a genetically divided society.
