Elective, consumer level CRISPR is the answer. People will not only choose it, and choose what changes to make, they will pay for the opportunity. This solves all issues relating to government intrusion on our rights, individual consent, and so on. Nobody is "deselected", nobody is sterilized, nobody dies, except the natural process by which future generations will replace us either way. This way, we have the choice to make those future generations healthier and smarter than the generations before them, rather than the reverse.
