With the advancement of computer games to the point that they can look almost real, I wonder why people don't leverage off this idea and put it to use for things other than games.

With Universities these days (well at least mine) they're increasingly putting lecture materials available on the course website.  In fact, for some of my software engineering lectures, the audio and Powerpoint is posted on the net, thus you can basically have the lecture at home (though I would still prefer the lecture theater).
So if this trend continues, you may no longer actually need to go to Uni for lectures...  But how would this be attained?

If you look at things like World of Warcraft, it seems that wee do have the technology to make things like "virtual lecture theaters".  What do you think of the idea?

If people spend hours doing repetitive tasks (for training) in MMORPGs, don't you think they may as well learn something whilst constantly bashing monsters?
