Thank you for you're comment, Jenna.
I did not want to get off topic, by switching from young "master" to old master, but felt it interesting to bring up.
In the case of the young "master" who may derive their status from superb technique with little depth and understanding, to the old master, who, has lost the crispness of the technique but possesses the depth and understanding of underlying principals of their art. Who would appear to be the true master in the eyes of the paying public.
Anyone care to throw a thought out................
Forgive me for not understanding that you were looking at it from the pov of the paying public. Yes I think that is a quite different set of lenses to view it through. I would say in the dichotomous example of "master" you have given that the paying public appreciate their stereotypes. In that case I would argue that BOTH of these are stereotypes that would satisfy the public perception of "master". Speaking as a member of the public, I would say that I like to see good fights in the ring or mats or even on screen in fiction. At the same time I appreciate the TRUTH (for me) that depth of skill cannot come without depth of understanding. And depth of understanding can only come from length of practice. That is my opinion as I have experienced it with the practitioners I have trained and fought with.
Again though that may be specific to the art. In Aikido I think age-related mastery and efficiency gains are notable. In boxing, there is a definite split depending upon application. Older heads bearing deeper understanding will ALWAYS have the measure of younger heads with superficial understanding. However, that is tempered by understandably lacking endurance. In the ring that is everything. Ring environment suits younger "master" types. Elsewhere, endurance is not the thing and depth of understanding that generates significant efficiencies ALWAYS wins (in my experience). I am sorry for digressing. I think the public like stereotypes. A young, fit "master" that can take on all comers would appear to prove theirselves worthy of the title in the eyes of the public I think. A more erudite, neater, more efficient master would also fit that stereotype of what it is to be a master in the eyes of the public.
