This is my view, too. I don't really like the philosophical approach I see in a lot of the Aikido dojos I've visited, but it works for the folks who train there, so I'm glad it exists for them. For some folks, it's just a good mix for them of physical work, philosophical thought, skill development, ritual, and cameraderie.This is true. But ...
The specific kinds of human activity that a person will find conducive to personal growth are particular to that individual. One person might find enlightenment through mathematics, another through carpentry, another through Aikido. A person who finds their life transformed through karate may not experience anything special from practicing pottery and vice-versa.
So if someone finds their life enriched through practice of Aikido, then more power to them. If they're getting what they want out of it. who am I to tell them otherwise?
