Well as there are several teachers in my family, I believe VE is just going to grow exponentially. You can already get your Bachelor's and Master's Degrees fully online, and you can watch your professor's through videos such as Youtube. Eventually, if holographic technology takes over, then you can be in a classroom where a teacher 500 miles away will be teaching 20 different classes all the same thing. Each of them seeing the holographic version of their teacher.
There will always be the need for physical teachers, but with budget cuts, the government will eliminate as many as possible.
