I'm sorry, but I absolutely have to comment at this point.
(Been following this thread for months).
Saying "you can't get XYZ" or "learn it yourself, I can't be bothered to explain it to you" (aka I can't explain it to you), combined with the inability to show a concrete real-world example of the benefits of a theory, means that the theory is absolutely worthless. Worse than worthless, actually. Even worthless theories are sometimes studied in order to see where previous researchers have gone wrong, to learn something about the way things have been (unsuccessfully) attempted in the past.
This theory is worse than that, because not only have people's requests for concrete, real-world benefits been denied, the theory isn't explained in sufficient clarity for people to be able to learn a lesson from it.
It just fails in every measure.
But, no doubt, this is because I don't "get" it. Since when was it always the audiences fault if they don't "get" the lecture? When does the teacher have to take some of the responsibility? I know that when I teach (chemistry), I take an awful lot of responsibility for my students understanding. How easy it would be to simply say my students don't "get" it!
