Everything you see in sci-fi movies is going to happen

I do believe that scientific advances will make many of the yet impossible things possible for us. However, I dodn't for a moment believe that it will be an easy ride for humanity as we move forward. The new advances will also be accompanied by new problems. Average age of human species will not rise by any significant margin in next 50 years. I read an article in which the proponent was saying that in next 30-40 years people will start living significantly longer than now. I don't believe that there is any possibility of that happening in next 100 years.
