Of course the interesting question is what happens on the interface where your rights and my rights collide... your right to freedom of speech and my right to live without being put in fear, for instance.

Try Michael Crichton... he exhaustively researches his books, and the science in them stretches a bit beyond what we can do now, but not to the point where it is unbelieveable. Also, this stretches from physics (Timeline) to Biology (Jurassic Park, Next). Highly recommended

Orson Scott Card - The Ender Saga... consider the fact that he wrote this ages ago... then read about everything he came up with based off of quantum entanglement and AI and the stretches he makes with technology... its a really fun read.
