Many people do not believe this will come true because they do not see it happening. However, if you look at the current state of technology you will easily see that it is being used, and that it is easier than ever. Many private companies are using these systems to watch both their property and their employees. Surveillance devices have become so small that it is now possible to make a camera and a microphone fit into a very small hole in the wall. Some companies are selling cameras disguised as smoke detectors.
Police admittedly use small microphones as 'wires' to get confessions in undercover operations.
It is entirely conceivable that the government could be watching us now. Perhaps, though only on a small scale. The people watching probably would not go directly into your account, that would be as illegal as entering your private room without a warrant. However, they could easily watch the packets of information running through their systems and rebuild the your private E-mail, or newsgroup transactions. This must be put to a stop.
