I think the pareto principle applies to aikido as well as everything else. 20% of those doing aikido may be interested in putting in the hard work necessary. The rest are happy showing up and putting in the mat time in a recreational manner, to feel good about themselves, spend some time in a social group of sorts, and to get "something" out of it. Nothing wrong with that,
I don't think we will see sweeping change throughout the art. Again, maybe that 20% that has been wanting "more" but didn't know where to look. Sure, some stuff will trickle down, out, over as these guys figure it out and take it into the norm.
But again, how many people are really willing to put in the time that this will take?
You know, it's an interesting question. For instance, my opinion is that Tohei's Ki-Society stuff would have changed Aikido as we know it, if there had been more people getting more substantive results, back in the day. As it was, the Ki-Society stuff was sort of underwhelming and/or tenuous, back in the early days, because there was nothing explicitly shown. It was more of a "feel your way" approach. And the waza at most of the Ki-Society dojo's was pretty loose, in addition. With a more explicit approach, more of Aikido than we might suppose could easily hop on board.
Certainly, I think that a lot of the "ki tests" are going to be far more accessible to newcomes, etc., so there will probably be a lot more retention of people due to that.
I also don't think that it's unreasonable to see some of the smart, younger crowd put in the time to become fairly formidable. More power can be generated than is obvious, Kevin, although I don't think that's what should be focused on so much at first. There is a real detriment in going to quickly for "power", rather than building up the basics over a couple-three (or more) years.
