The only classrooms that will be made irrelevant are the bad ones in which professors simply stand at the front, lecture, and ask "does any one have any questions?" Classrooms and laboratories that encourage student participation and require hands-on activity will never be made irrelevant. If human contact was that unimportant, then nerdy 14 year olds would stay home and play Halo with each other over the internet instead of sitting on the floor sharing a bowl of Flaming Hot Cheetos. Humans are social creatures. They like to hang out together, whether its learning, playing, or working.
