Dystopian Futures

Today my partner and I went to the new movie Transcendence. After the movie, we began discussing how so many dystopian stories contribute to the fear of science. In Transcendence it’s AI technology, In Divergent it’s mind control, In Hunger Games there is the fear that the elite will control all the technology and use it against the rest of the population. These fears see to follow fears held by the average person. But are these fears right? Or are they simply brought about by a lack of understanding of science and technology? What if there were a dystopian novel/movie that went in the opposite direction? Are there any that already have?
