The most unrealistic part of Gattaca is how confident they are in their DNA-based projections. Like in Gattaca they can determine you are unsuited for a particular career based on your DNA. But we are nowhere near determining someone's potential intelligence based on their DNA. I think most scientists believe that is impossible - DNA does not determine your intelligence with that much detail. I do think that soon it will be cheap and easy to sequence your own genome. There is great hope for personalizing medicine, treatments tuned to you that are twice as effective. But genetic screening will not take on the role it does in Gattaca. A genetic screen will not give you better information than a 1-hour interview. (I'm not a professional in this field but I did get a master's in computational biology, working on genome sequencing.)
