Thread hijack alert! Forget what - why is IT?
If aiki is so hard to see, learn, etc then how did it ever come into being? What evolutionary advantage can be gained if the cost is so high? Perhaps a fortuitous development with nothing to do with evolution (spandrels, exaptation anyone?) ... certainly behhoves one to take advantage of such a gift.
I ponder therfore I am ponderous.
