Marc Prensky response to Douglas Rushkoff

As usual, McLuhan was prescient. But I see nothing "opposite" in the two quotes. The first quote says new technologies upset the old people and they ought to "get with" them. The second says they typically don't. That, in my opinion, is one side of the argument (the correct side, as I see it), i.e. the "old" people are helplessly (and, worse, aggressively doing damage by being) stuck in the past. Where do you see McLuhan taking any other side,

Doug?

Best,
Marc
