I know this might sound bad but I actually think the reality portrayed in Gattaca is not that bad. I mean, if you put aside the discrimination faced by that part of the population born the natural way, you have a society where almost everyone is healthy and will live longer than previously possible, and is of great contribution to the community. I think that's our future and it doesn't scare me that much, what actually scares me are the endless genetic mutations that result in a wide array of tumors and untreatable diseases.
