I've seen most of his talks, actually I'm a fan. I wouldn't consider Clojure to be a good example of purity though - it has both LISP purists as well as FP purists (Haskell) against it. Actually it is quite pragmatic for running on the JVM and even has optional typing. If elegance and simplicity are achievable without making too many sacrifices, great! I'd choose Clojure over C++ any day.
