But that's a different topic: "Are classrooms a necessary component of education in the future?" is a very different question than "Are professors...?" I think the answer to both is probably "yes" but certainly not in the quantity they are today. I wouldn't want to be an employee at a teaching college over the next 10 years, much less a professor. The higher ed bubble is about to pop (between new technology, skyrocketing costs, and reduced perceived value, it's going to get hit on every side) and its going to be ugly when it does.
