Relations of Dystopia

Along with the fact that Brave New World has a society that totally perfects in technology and the idea of mass producing babies, why are they made to do a certain task for the future and the society? Say for example, the mvoie "I, Robot". Why is the people in that society especially the police force rely so much on the robots to do the jobs of the people in that society? Is it to make the society more peaceful? Or more happier like the novel Brave New World? I seriously don't think having robots installed in our homes will make us feel secured and safe. Haven't all these scientists ever thought about the flaws and technical difficulties it may have? The odd part of both these dystopian society is that the people in those societies actually cope with the changes. For the film, I noticed that the creation of human technology actually changes the way people in the society acts.
I believe this dystopian society defies the laws of nature because it is always true that what nature creates, nature can destroy. But what about the things that human creates? Can it be destroyed as easily as nature can or will it actually go against us? Same thing for humans. Nature creates us and it can destroy us, but the actual mystery is that we can prevent nature from destroying us. As I' am typing this now, I have just noticed one amazing similarity that both the novel and the film shares. The character Bernard Marx in Brave New World and Det. Del Spooner in "I, Robot". I felt they are the same exact character is because both characters showed an element of uniqueness that both readers and viewers can distinguish. What I mean by that is that Bernard Marx is an Alpha but is different than any other Alpha by being able to think in his own way, not the way he was made to think, which is happiness all the time. As compared to Det. Spooner in "I, Robot", he is a half robot, half human who does not believe robots should be used in the society. Basically, the things that we create can never ever be what we image it to be. An overpowered society will always be abolished by the inferiors who believe that there must be a change in the society. Not just dystopia, but also in our living society. We live with a law and we can always change the law to make the society a better place for all to live in equilibrium.
