The internet is way the hell more flexible than any brick and mortar classroom. It can be a supersize lecture for 1000s or a small chat room of 4-5 people. Plus, quicker and slower students aren't tied to the average speed of the class. You move at your own pace. Teaching is teaching, whether you're sitting in the front row, sitting in the back row, or sitting at home. Any problems you can think of regarding the learning experience can just as quickly and easily be solved through better on-line links.
All teaching methodologies, examples, etc. can and will be archived and filtered into the best examples. It's a ton more cost effective efficient, and it's a ton better quality (or will be). The internet can be a helluva lot more reactive than one teacher walking around a class of 30 students seeing how their arithmatic problems are going. Just take a look at mmorpgs, instant messaging, chat rooms, forums. Students can learn from each other, from professionals, from the elite very best. Again, the other 99.9% non-elite, non-very-best get the axe, because their efforts are a total waste of time, money, space, and duplicate effort.
That's the way it's trending. Your grand-children will graduate with the equivalent of PhDs in their teens because of it. Just think back to all the wasted time inherent in the school system, from walking to classes, taking attendance, drama and angst, disruptions, bullying, driving-walking-bussing, missing class because you're sick, it goes on and on.
You can sit in a virtual live classroom too, with fake 3d images of students sitting at desks, or with other live virtual student images. It can be sliced any and every way, in real time, with real time feedback measurements and results. It's magnitudes upon magnitudes more efficient, more cost effective, and better quality, exactly how the free market is magnitudes more efficient, more cost effective, and better quality than socialism.
With equal quality equal access available to all, if you want to keep robbing taxpayers to fund school buildings, teachers, adminstrators, athletics, then hopefully you and your kids will get reciprocal bombs going off in your schools and neighborhoods. Don't pretend you're not a theif by voting for taxes to fund public schools, espcecially when a better alternative exists for free.
