Hm. I haven't read the article, but the excerpts printed here are not news. Opinion aside, I'm sure most people know that ukemi makes aikido techniques look good, but I'm also sure that most people know the importance of ukemi in keeping training partners around for more than one or two throws.
Anyway, I'm becoming increasingly convinced that we are learning principles (body movement, spacing, timing, blending) rather than specific techniques done in response to specific attacks. The upshot is that I don't expect a technique to work outside of the dojo the way that it does inside, but I expect it to work.
