I'm not sure how serious you're being. Assuming full seriousness: In Gattaca, parents somehow got to choose between thousands of potential embryos to maximize chosen traits. This is not biologically plausible; even in IVF, you only get to choose between a few embryos, so you could never have anything like as much control over abilities and health as we saw in Gattaca. The most realistic use of embryo selection is so that you could simply make sure that -- for diseases where you're a carrier and had a 50/50 chance of passing them on to your children -- you choose the embryos without the pathogenic mutation. In this new paper's technique, you just get an abort/don't abort decision over your fetus after seeing what is probably its genetic sequence. We already give parents this decision via amniocentesis. It seems unlikely that people will attempt to go to great lengths to get "the perfect" fetus this way, because one fetus at a time doesn't give you many options to choose between. More likely, we'll just move from "sometimes parents abort fetuses if they're going to have Down's or some other grave disease" to "sometimes parents abort fetuses if they're going to have a serious genetic disease". This doesn't bother me much, nor does it seem to have much of anything in common with Gattaca.
