Yep. MOOCs don't serve the important part of the teacher's job. Teaching is best as a dialogue. A videotaped lecture is little different from a book, in that the information is fixed; worse, unlike a book, you don't even get to read at your own pace. It's not without value, since some things adapt well to that and different modes work for different people, but it's still missing the two-way communication that a real teacher provides.
People have pushed MOOCs largely for the learn-a-bunch-of-facts classes, such as science and tech. Technique is also a "fact"; it's stuff that can easily be tested and graded. The things that are missing are the parts that make us consider a student well-rounded: history, literature, sociology, art. These sound trivial to nerds but they're about innovation and communication. They, too, have to be practiced, and it's not something that can be memorized. Even the STEMmest jobs are ultimately about people: seeing what people want, finding ways to tell them your ideas, building up a story together. And that's something that a real teacher can help with, and a videotaped teacher can't. (Nor can a videotaped teacher answer questions or ascertain just why a student isn't "getting it". Even a "great teacher" is little more than an actor when on video.)
Teaching is too often undervalued as if they were just handed a book. It's a skill of its own. We STEM nerds often undervalue that skill because it's not easily graded on a multiple-choice test.
