We were learning about this in school. I’d imagine the majority said they wouldn’t do this, but there’s definitely some who thinks it’s a good idea (like my uncle, ahem ahem).
But if you had the option to mess with genes and give you the “perfect” baby and you knew what they would look like beforehand, would you do it? You could give your child “desirable” traits while the children who don’t have those traits are inferior, or you could love your child considered “inferior” by society as they are.
We’re probably within being able to do it within the next 10 to 100 years.
Once the genie is out of the bottle, there’s not going to be any turning back.
There might be a few isolated groups that refuse the treatments, but I am sure that once the option is out there, people will take it.
I can see some interesting lawsuits in the future. Suppose the child develops, say cancer, and knows that the parents could have given them an anti-cancer gene*, could the child sue the parents?
*I picked a disease at random. I couldn’t think of a genetic disease off the top of my head.
