It is not meant to be. Let me summarize your accurate summation to get to the point of the criticism -- you notably take my comments, even the critical ones in a somewhat different spirit from, well, other people.

Indisputably, that is what is reported. Now the two themes of your observation are 1) faster results and 2) impressing others.

And then lastly:
None at all. Now, my points in kind. In most organic things, faster growth tends not to to be deep or durable growth. Your situation coming from a firm base is an entirely different matter when it arises from a simple desire to broaden experience.

Plateau stages of growth, everyone gets them, because it is the natural pattern of all growth. That is also an aspect of of In-Yo pattern.Vulnerability exists to such entreaties (faster, more impressive). Shifting to an accelerated mode may have its commendations, but let us not pretend they are without possible costs.

Impressing others is a door into the moral problem that troubles me seeming creeping more into aikido. It was always there, of course, people are still human, but it was a recognized fault and aberration -- not a sought for attribute of training or teaching. A number of those people you mention "impressed" many people without ever meeting them. As to the type of problem presented with this I suggest reading closely Prof. Goldsbury's most recent "transmission essay." about the role and the nature of the influence wielded by Deguchi.

Reputation is only as good as the critical opinions of a person with personal knowledge that form it. But when reputation is framed on how impressive person is, well, again read that portion of the essay.

If someone gets personality and reputation in front of the work it makes the person the issue and not the work. One may interpret that badly, of course, but only if one is wishing to be impressed rather than reading to see if something is simply true or useful. If reputation is the issue then even merely physical or conceptual criticisms is too easily perceived as tearing reputation down.

But if I am successful in my effort, reputation will not matter as much, -- more people will have the tools to be far more critical -- of themselves and what they are, and should be taught. And of what they are actually seeing in the videos that started the thread.
