Brin's Transparent Society stood out from the mass of now forgotten predictions about the internet because he understood that technology had made old levels of privacy impossible: "The djinn cannot be crammed back into the bottle. No matter how many laws are passed, it will prove quite impossible to legislate away the new tools and techniques." The best encryption systems in the world are of no use if the state or another public, private or criminal organisation can place a miniature camera behind you while you type, or insert a program into your system to monitor your key strokes. Instead of trying to protect the unprotectable, Brin called for political change to match changes in technology. He envisaged possible responses by imagining how two cities might look in 2018.
