Aikido desperately needs people to focus on how to develop training which could potentially produce another O-Sensei, another Tohei, and Yamaguchi, etc In large measure this isn't happening today.
I don't think that aikido needs such "products". It would be contrary to O sensei way of being. Don't forget, that today’s popularity of aikido is an idea of first Doshu, not Founder himself.
J.Kano sensei developed a system of very efficient teaching large body of students. He did it in accordance with his goals. O sensei never ever thought in such categories.
Founder understood very well, that aikido is a tool for very intimate relation between Kami and a human being. Such things by its nature are addressed to very limited audience, and today those interested in it will find a true transmission from Founder. The others, who prefer to stay on purely technical level and learn technical tricks, will learn it too. That is a law of natural selection.
Also, our expectations and judgment is quite different from the view of people 50 years ago. On technical level, there are many new different ideas (MMA, FMA,..etc). Even today’s sports of combat are very different then 50 years ago (ex boxing or wrestling). Today not very many ppl are impressed by traditional teaching system as they see very impressive results of modern, backed up with science and technology, training methodology.
