If you watched the Jetsons, Star Trek and the Twilight Zone weren't you the ones who said, "wow, the 21st century will really be something". Here we are and people who are over sixty are turning down the opportunity to free themselves from trivial chores so that they can do things that are truly important.
As a teacher, one of the common complaints I have from students is about their grandparents. They won't let us use our cellphones, tablets, X Box, etc when we go to visit. Whether we like it or not, technology is here to stay and it's really in its infancy.
A family member in the military is trained to intercept and listen to cell phone conversations. In fact, a few years ago, there was a number you could dial and listen to the airwaves and mixed cellphone conversations.
As someone else stated, let them listen, what will they hear? We're all human beings and as unique as we would like to think we are, we're not. Unique in some ways but our daily habits are all pretty much the same. We all eat, sleep, have relations, and go to the bathroom pretty much like any other species.
In most cases, like the teachers I train, they are afraid of technology and that is why it isn't used. Lack of knowledge and information. Embrace it, use it, and it may just be your best friend one day.
