I dunno man... that sounds like a circular argument to me. If you have to master somthing to know what someone who looks as tho they are mastering it has mastered it, is it mastery or your idea of mastery based on the fact you believe you have mastered it?
How do you know when you have mastered it? When you look like someone else doing it? But how do you know that looking like them is mastery? They may not be a master and by your argument you wouldnt know... heck, by that argument we can't even be sure Hatsumi is a master since we are not masters... I mean, some people can say they are and therefore they know he is, but how do we know they are...
I just can't buy that. Sorry. I get where you are coming from, but I think the idea falls short.
In fact, you and Tim and all the rest of you will forgive me, I don't know who most of you are, are you masters? Is your opinion of the subject based on that level of mastery that allow you to make that judgement, or are they just opinions, like mine? because I am certainly NOT a master, and can only make my judgements based on what I have seen, and to an extent, heard from others.
