I think identical twins taught have us much of what we need to know about a person's genetics vs. experience and conditioning as far as effects on their performance of certain tasks as advlts. The idea that we'll get to a point anytime soon wherein an obviously exceptional person with supposedly inferior genetics is likely to be barred from any jobs that don't involve a mop is a little absurd. I've seen the movie...it was quite some time ago, and I thought it was decent. I liked the art direction, and I can appreciate the concept, but I'm not sure humanity has quite developed that particular manner of tunnel-vision as of yet. Potential doesn't lead to such a simple, linear path to results in anything but an ideal, closed system. There are too many environmental and incidental factors involved to be able to use genetic potential superiority as such a absolute yard stick. I think we understand that well enough that we're not going to see that type of DNA bigotry anytime soon.

It's also not a new idea...I think my favorite version of that concept is Player Piano by Kurt Vonnegut. It's a story with a bit of a different message, but is very similar thematically.

I think how we look at stuff like this from an ethics standpoint would have to change a lot before it becomes antying that would merit any concern.

then again, at the same time, we are making leaps and bounds with things like advlt stem cells. so, its just as reasonable to say that people could be cured of their defects well before we are engineered to be "perfect" from birth.
