My college students marvel at my ability to spot text messaging and to hear the drone from a backpack signaling a missed message. I am upfront intolerant of addiction to the cell phone, to text messaging, to Facebook fanaticism, to all that passes for communication and makes genuine interaction impossible. I think it is possible to me wisely modern. German philosopher Martin Heidegger warns that "we invent but we do not understand." Be smart. Make technology work for you and know its limitations and pitfalls. Be its master.
