It's a pity Rich doesn't film all his talks himself. The way he translates his passion for language design into eloquent presentations is a big part of what drew me to Clojure in the first place.
Surely there is another copy of this video including the whole talk. It would also be nice to see the slides.
Im pretty sure there isn't. I know almost all videos of clojure and I have never seen the rest of the talk.
There are lot of talks about these concepts you can watch. So its not to bad that this one is missing.
