Stop implying something I've never said. Shout as long as you want, but the original link (and Gataca, imho), isn't about eliminating illnesses as such, but about either favoring certain embryos and/or forcing people to take careers that fit their genetic outfit, no matter if they want to or not. So forget things like freedom of any kind.

Selecting embryos due to their (perceived) chances for future college is a f*cked up idea. It's euthanasia for nothing else but, basically, intelligence. And it will, once again, favor those who can afford it and leave all others in the dust.

Eliminating illnesses on a larger scale is a completely different matter, but even that purpose is debatable. There are parents who are willing to give their unborn child a chance even if they know that it has some kind of genetic defect. And even if such measures would be reliable in the future, they'll most probably wouldn't be for the masses but for the few who can afford them.

The end result would be some very healthy, very intelligent rich people and an endless stream of poor people who, due to their "faulty" genetic composition, would be seen as mere underlings, only there to serve those that are "worthy" of good education and jobs.
