As another comment in the thread said, this situation is fairly different from a cochlear implant for a number of reasons. This situation is most similar to child being born to deaf parents with normal hearing. Not the same as a cochlear implant at all. The choice in this situation is being deaf or having normal hearing, no inbetweens.

Me personally, I wouldn’t want to pass on any of my genetic gunk to my kids in the name of culture, communication, or community. That’s just cruel and unusual. I would not be surprised if my kids resented me for it if they knew it could have been prevented. Even more so if cellular reconstruction technology is available to repair stuff later in life. And it’s not like they can’t participate, they’re still your kids, they’re just different from you in a small way. Humans are adaptable.

Culture should not always be preserved. My family has had to learn that the hard way.
