The 'science' in Gattaca is just an excuse for segregating human beings based on some arbitrary criteria. As others have pointed out this is nothing new. What is extremely irritating is that people actually think that genetics works the way it is portrayed in the film. This is patently false. Yes, some portion of what an organism is is determined by the primary sequence of its DNA. It turns out that the contribution of primary sequence alone is quite small. Look at all the naive genome wide association data sets that have revealed that primary DNA sequences are in most cases very poor predictors of phenotype. This should't be surprising to anyone who has even a cursory understanding of evolution and the interaction between ecology and development. Yes, this is classic nurture vs nature stuff. The fact that people want to claim that science could actually give us a universal, deterministic and predictive answer about the future should quickly alert us that the principles on which they are basing their predictions is not science and not predictive, but instead an ideology based on prejudice rather than evidence.
