Aikido is long and SLOW way. You are at the very beginning of it just as I am after 9 yrs. Why the hurry? Are you often attacked by muay tai fighters or others? Effectiveness will come if you are patient and diligent. If you are you will get much more from aikido than just that. If not then you are right, it doesn't worth a penny. But it's not aikido then which doesn't worth it. It's what you achieved instead of it.
Aikido is fundamentally a MARTIAL art. Honestly the whole argument you hear of "ohhhhh well we study aikido to NOT get into fights" is complete garbage, im sorry. I used to think the same as you "effectiveness will just...come" like one day it would just show up or something. Do you seriously believe that? You honestly think with the training you get now you can you can reach this magical invincible plateau when we are taught that uke has to follow and we need to be in harmony? Its nice in the dojo but in the real world...i dont think so. The point is not "how often are you attacked by x or y" the point is from a MARTIAL point of view i think Aikido is severely lacking, unfortunately what we do have is a LOT of this hippy "aikido is the martial art of love" bullshit which ruins it imo.
I dunno maybe its the old pre-war Yoshinkan style O Sensei in me talking.
