That is what most folks will do - that, or something they wish existed that isn't really Aikido. The latter is probably more of what I end up doing, even though I have more grasp of (Ueshiba's) Aikido than most would. That still highlights what people think Aikido is and what they wish it would be (to suit them better). Might never change Aikido, but it can be useful when thinking about what folks like in their training.Fair enough and people can discuss whatever they want.
The problem is this: when people with little or no aikido background discuss how to improve aikido, what they are really discussing is how to make it into what they already do. Underneath it all, the BJJ guy wants to turn it into a variety of BJJ, the Kyokushin guy wants to turn it into a variant of Kyokushin, etc.
Everyone has the right to an opinion, but if the opinion is uninformed, the opinion is worthless.
There would be some who would like to see Aikido go quite the opposite direction - more away from any kind of combat effectiveness, and more into the study of ki, philosophy, and character development. I think that's a lot of what happened with Tohei's Aikido.
