This could be titled "Static typing is not going to save you"? There's nothing but static typing languages and related theorem provers from the timeline slide onwards and the conclusion is that it's too hard. This is a good companion piece for the recent Rich Hickey Clojure/Conj talk :)
I don't really see where you get that. Is dynamic typing demonstrating a lot of sustainable success?
Languages that have forgone static typing aren't necessarily trying to solve everything using language types at runtime. See eg Clojure's approach. Or SQL's.
But at the base popularity-contest level the answer is clearly yes: Dynamic languages have been on a roll for the last 30 years - Perl, Python, Ruby, Erlang, Clojure, even JS.
