I know that empirically, in terms of what society thinks, you are probably correct, but what is wrong with designer babies? Isn't it the only way we can continue the further improving and developing of the species (instead of making it worse by artifically keeping people with genetic diseases alive and reproducing), at the same time also avoiding the more horrendous parts of natural evolution and selection like genocide, race wars or idiocracy-styled trends of selecting by the dumb metric of sheer number of kids?
