If you're going to make the comparison with vaccines, and if history is any indication, the more realistic worry would be the other way around (since that's where the money is): that genetic modifications will be mandated, and that those who object will be discriminated against.
[And no, I am not anti-vax, nor anti-gene-editing.]
“What do you mean you haven’t modified your chromosome 7 CFTR gene? And you’re planning to have children???”
I don't know anything about gene editing, but my grandmother was a carrier of the BRCA mutation. It would have saved a lot of heartbreak in my family if that could have been detected and repaired. My aunt, mom, and brother (age 4) all died of cancer. I'm just glad that my mom didn't know she had the mutation and passed it on to her child.
It wouldn’t be crazy if I teleported 50 years in the future and heard someone tell me that not doing this is akin to child abuse. Obviously all suffering is relative, etc. etc., but it’s just interesting to imagine a world where the societal pressure to make a perfect child is high.
