There are many who would agree. Many more say "not within our lifetimes" but maybe someday. The technology is advancing rapidly.
For instance, online PE might be a possibility in the very near future - look at the Wii activities, if a 'vitals monitoring' device was added. Also, simulators and 'sensor rich' artificial human bodies may eventually provide online 'lab stations' for a very futuristic classroom, without human face-2-face instruction.
Seems like science fiction? Maybe.
