Generational

While facilitating a class of 21 year old seniors, I've been struck by how glued they are to their computers. As I've meandered around the class it is evident that they are checking on lots of things--including some of my comments or references. What is striking is that when I ask a direct question, only a hand full feel compelled to respond while the others just keep doing their computer work. I wonder about the loss of discourse and the unforunate apparent reiforcement that "being in your world" means to unshared wisdom?
