If you have ever watched the TV show Black Mirror, it does an exploration of what it would be like to have instant access to know everything about a person by looking at them.  The technology becomes a commodity and results in the destruction of personal relationships rather than a dystopian big brother society.<p>It seems to me that is a much more likely future than a criminal and government oppression future.  Is one of them inevitable?  Probably, but not any more than our present is someone else&#x27;s future.
