I believe the movie Gattaca’s premise is around this subject.

Either x-men or just less people with genetic diseases. Not sure which one though…

… Bioshock

KHAN!

I imagine genetic traits like down syndrome or bodily mutations would be a lot less common.
Autism, ADHD, depression, anxiety too depending on what kinda healthcare this fictional society has.
if it’s anything like plastic surgery, nothing will happen except maybe down syndrome and bodily mutations.

if it’s cheap though people are gonna go ALLL out on bodily cosmetics. Id want a spiky dick with one of those spiky balls at the end like that one dinosaurs tail.

A global society where science has advanced enough and everyone is wealthy enough to be able to do this? They can do what they want with it I guess, we’ll never see it
