Re: Competition in Aikido
One, having watched competative fighting sports from wrestling to boxing to MMA, I don't see that the inevitable butt kicking leads to humility. For those inclined toward humility, it will be there regardless. For those inclined toward over-large egos, getting ones butt kicked probably won't have much of an effect.
Two, what form would aikido competition take? Kata competition? I don't see how sparring could even be possible.
