Are wearable cams going to aid society or mess it up more? Encourage people to behave better? Or contribute to the blurring of lines between everyday reality and visual entertainment? We'll all see ourselves more clearly or we'll all move permanently "on stage"? All of the above?
I generally think this interconnectedness has harmed more than helped because of our lack of social restraint, which is encouraged by devices and technologies like this. Much the same way as I figure the internet, and other social technologies have helped to destroy the family as a unit by helping to kill the seeds of love as much as growing the seeds of infidelity.
It used to be much easier to stay in a relationship with someone because you weren't around them all the time. With today's technology you're never functionally without them. They can tell you about their day AS IT HAPPENS. Having a good hour-long conversation with someone has become very difficult as a result.
I don't necessarily think all this HAS to be a bad thing, but it does depress me a little bit simply because I believe the family unit has a kind of simple elegance to it that should be preserved for as long as possible for the benefit of humanity at large.
