Hmm, just as most parents will, in the future, probably not be hermaphrodites, what makes you think they will want their children to be? Where do you see this great urge and desire for hermaphroditism? Most parents want their children to be able to adapt comfortably to a ‘normal’ social environment and since hermaphrodites in our society often have hard time doing just this, what makes you think it will be any easier or any different in the future?
After the first wave of hermaphrodites, I could potentially hypothetically see this, after all there would be a high security of similar peers and adults, although my bet is that the parents would still want the children easily relatable to their own experiences, but where are you going to get that first wave in the first place? Maybe among some fringe groups, but in general I find that idea highly unlikely.
The best analogy for how genetic engineering in the futue will be handled is plastic surgery today. Plastic surgery was initially developed for burn victims and as such most people favored its development (like g.e. today is favored for similar life threatening illnesses), however the very wealthy were soon able to afford plastic surgery for nonmedical expenses and see it as a luxery, this ability has slowly drifted down to be a reachable dream for most of the Middle Class.
And what do people want with plastic surgery? To make themselves look completely different? Some, yes, but most simply want to accentuate those traits that were already favored in society, i.e. society appreciated ample bosoms, plastic surgery made cartoonishly ridiculous breasts possible, our society favored women on the thinner side, liposuction and other advances made walking caricatures like Twiggy and her ilk possible for the very wealthy, so, probably, in the future people will want attributes admired among natural elites, but more so to a cartoonish degree.
Like people with romantic passion? Nymphomaniacs can be designed with uncontrollably powerful need for frequent sexual intercourse.
Like macho men? Men can be tailored who make Rambo look like the absent minded professor.
It’s going to a wild and weird world our children grow up in!
