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.

One solution would be for universities to offer a CIS degree track that carries teacher certification. Right now, I don't know of any schools where you can get an education degree in computer science or information systems. As a result, you get people teaching IT/CIS who have their primary training in another field. Like the coaches who get stuck teaching social studies because they need to fill time, some IT teachers are the English teachers or Librarians who get thrown into the computer classroom because they are really good with Google or know how to change themes in PowerPoint.
