Justin Smith covers it for me:
I optimistically hypothesize that there will always be at least one martial art that values and respects peace, has natural relaxed movements, is practiced in a joyful atmosphere, where people can apply what they learn to areas outside of martial arts. Such a martial art may justifiably be called aikido, even if it is not the original aikido.
Don't care what you call it. We all have the same teacher OSensei had - life. (And they said his classes were tough!)
