"Hey, you've got a broken gene? Sucks to be you, my rigid ethics requires you to play the lottery with worse odds than the others!"
In another thread about the same subject, I mentioned the issue of color blindness, and how some professions are open to ~92% of men and ~99.5% of women (because of how it's inherited). Society seems to be quite uninterested to start some wide campaign to replace color-coded information, even during the 2010s when the equality debate was active, it was never "upgraded" to include male issues like these.
With DNA editing, this problem could be fixed on the other side (along with much more serious issues that can affect an unlucky individual).
I don't know why there is so much fear to be out-competed by a hypothetical "superhuman", when the most easy implementation of DNA editing seems to be fixing genetic diseases (often "flipping one letter" to the correct one)?
Nobody requires you to have children. Your problem could just as easily have been infertility. So instead of gambling, you can choose to treat having a genetic disease like being infertile, or you can dabble in eugenics. My "rigid ethics" frowns on eugenics. We have lots of children who have already been born who need help. They may never satisfy your desire to see your (admittedly bad) genetics reflected in the world, but maybe they could give a legacy to your intellect and compassion?
Eugenics was once very popular among the middle and upper classes, though, before there were incidents. There's no reason to think that it won't be popular again. I think that society as a whole has to decide how we treat human lives though; your children don't strictly belong to you, they belong to themselves and are protected by the state (even against you.) I'm totally comfortable if we decide that this sort of thing is going to be criminal, or if we decide that this sort of thing is going to be mandatory. I just know where I sit on the issue.
And I also know that the places that eugenics survived was in things like dog and cat breeding, and the preferences of people for dogs and cats did not make them healthy, it made them interesting. Ready for the human version of "Twisty Cats"?
The taboo against genetic repairs is more comparable to antivax, rather than eugenics. Every part of the medical sciences is an intervention against "nature taking its course", in order to prevent harm to the individual.
