Learning is just that and is not or should not be placed in a cubical or sealed inviroment. But thats just my personal thought
I agree with this thought. But I also think there is such a thing as learning at various depths, and unfortunately, in the case of kata (and this is still more the case of TKD hyungs), there is some difficulty in learning at what I regard as the most fundamental levelthat of the encoded combat applications that the extremely experienced fighters who created these kata found effective and reliable in violent conflicts.
We don't know what was in these pioneering karatekas' minds, of course, but we can apply robust, testable reverse engineering principles (of the sort itemized in a number of recent books on bunkai by practitioners who are serious researchers as well as advanced practitioners) to figure out some plausible interpretations that we can then `field test' for effectiveness. I've noted a number of posts by members who seem to refer to reverse engineering as though it were an obscene expression, but I have no idea why: everyone from forensic scientists to prehistoric archæologists use reverse engineering to derive (testable) hypotheses about the purposes for which certain objects were designed. So in principle, we ought to be able to supply the fundamental level of kata understanding to students in dojos in order to help them develop their ability to use their karate training (including KMAs under this heading) in the way envisaged by karate's creators.
But that's not what usually happens. Instead, depth of analysis is replaced by emphasis on kata-collecting, where the number of separate `dances' you can reproduce on command is way more important than what you can do with the sequence of movements the kata present you, and your ability to analyze those sequences to see the coherent sequence of combat
moves expressed therein.
That's the sealed environment that I believe has been imposed on the learning of kata/hyungs in their true depth, partly as a result of an instructional system which for the most part disconnects them from their fighting origins, and partly as a result of their incorporation in the competitive tournament model as a kind of performance art.
If that's all some want, fine. But the others should be able to get training in the understanding and combat usage of these forms, and the fact that these are still considered to be somewhat exotic, or marginal, isn't fine at all.
