If you want to see a film that gives perpsective on this kind of thing, try GATTACA. The only problem with that film being that the guy SHOULD have died at the end. You are emant to think it is discriminatory against him that he would not be allowed on the space programme because he has a genetic heart coniditon. Huh? They wouldn't let anyone TODAY on a spaceship with a weak heart! That's not because they are being evil, but because it will most likely kill you on take off!
But the rest of it is rather good- though it does depend on us being able to custom design babies, and the inevitable two-tier system in society that results.
It also, incidentally, has one of my favourite wuick conversation exchanges ever, when the policeman is interviewing the guy in charge of the GATTACA institute, with all the highly fit genetically desinged people exercising in the background. The policeman asks what the exercises are for, and the head (played by Gore Vidal) says he has them all tested regularly.
"But if they are all so superior, why do you need to test them?"
"Simply to make sure they are living up to their potential."
"Or exceeding it?"
"No-one exceeds their potential."
"And if they did?"
"That would simply mean that we did not accurately gauge their potential."
Which is not only a neat reminder of what the word potential MEANS- it is something you can NEVER exceed because your potential, by definition, is ALL you can do- but it is part of the lesson of the film that no matter how accurately you can map someone's skills and body genetically, you will never accurately assess what they can do.
But that is still no excuse for a man with a dodgy heart going on a space flight...
Anyway, the big dig deal in GATTACA is the fact that babies can be designed to be strong, healthy, clever, well-behaved (and in a sequence cut from the film, heterosexual- removed because of the dodginess of whrther it is genetic (no debates on that plase, that is just why they removed it))- but it COSTS, so only the rich can have babies like that.
So it might be very important that genetic development is always public sector, but that seems unlikely. We may otherwise end up in a world like GATTACAs- which is not a BAD world, it is full of bright, strong, healthy, ambitious people making great strides forwards for the human race; just that it is also full of an underclass of genetically 'poor' people whom no-one will give a decent job to.
