OK, this was a bit of fun to read, (thanks for the link), but frankly it a rather poor straw man argument. The basic problem with all of these futuristic visions is that they forget that the classroom teacher has to reach a group of people with (sometimes vastly) differing learning skills. It's not really conceivable that the "super teacher" can reach twenty kids with one presentation, much less thousands.
It may well be true that much of the *content* in a lesson will be drawn from the internet in the future, but the *lesson* will still need a professional to guide and mentor differing learners to grasp the content.
If a teacher claimed that every concept they ever presented to a class was understood equally well by all the pupils in the class, we would be justified in thinking that the teacher in question was somewhat delusional, but that is exactly what this article is suggesting.
Skilled classroom teachers are not going to be made redundant any time soon,
