I think I would be okay with germline editing too, in selected cases. It's not like a child is going to say "hey, thanks for not fixing my cancer-causing mutation when you had the chance, mum".
"The social and political implications of gene editing are also huge unknowns, and unfortunately there’s been scant debate among policy makers and the general public."
There are a lot of genetic defects we can engineer away. There’s a lot of other things that aren’t defects, but social pressure will make people want to engineer them away.
For example, when I was a child, British tabloids were saying “Abortion hope after ‘gay genes’ finding”: https://www.pinknews.co.uk/2019/08/30/gay-gene-newspapers-19...
(Bonus points as the gay gene didn’t really exist; but as I’m bi, people like that would’ve tried to eradicate me before I was born if they’d had a way to do so).
As I expect my resistance to social pressure to be exactly average until shown otherwise, I sometimes find myself wondering what things I falsely believe to be real defects that would be moral to eradicate.
