I've been thinking about Gattaca a lot lately too. It's interesting to me how in the film the mechanism for controlling genetics was to create a bunch of zygotes and then to pick the best one. But what seems to be happening now (the creepily named CRISPR and all that) is that people are editing existing DNA and controlling how DNA functions in living people.
