Big Brother All Over Again
The societal issue is one that we have faced many times before, most recently with the advent of cell phones, the location of which can be tracked very closely. Privacy and anonymity are quickly being lost. If you can be uniquely identified by a computer from many meters away while you are totally unaware of the ID being made, then you simply can't go anywhere without being recognized and even tracked by anyone with the technology and infrastructure to do so.
What is the problem? What legitimate purpose could I have for hiding my identity or whereabouts? If I am not paranoid enough to believe that those in power have any reason to prevent my profitable pursuits then is there any reason to hide?
I'm afraid that just may be the problem. Humankind has a terrible history associated with the phenomena of those in power crushing any possible attempt by any potential competitor to upset the order of things. We all want greater safety in our society and technologies like the one mentioned above may offer that increase in security. Like any technology, these can be misused by those that possess them. In my opinion, the best way to prevent such misuse is an understanding of those technologies. An understanding held by a well informed, well educated and involved population.
