I would actually disagree with even this point. it is more a thing that happens; to the extent that you can do it or use it or apply it, that reduces to a matter of you being in the right place at the right time (possibly with the right structure or alignment).
I'm not sure I'm with you on that, but that's not really my point.
My point is that there is a very big difference between aiki
and aikido. Just because you see aiki
in something doesn't mean there is aikido there. To say that MMA fighters (most of whom have never trained aikido) are doing aikido makes about as much sense as to say that every musician who improvises is playing jazz. Sure, improvisation is a foundational, unifiying concept of jazz, but that doesn't mean jazz has a monopoly.
