Personally I find selling excellence easiest without sweeping negative generalizations like they claim in their summary slides[1]. Presentation feels more like a blame game about how people have done things wrong in the past than highlighting success and features of Haskell.

[1] From slide 152:

   - Old East Coast tech culture valued quality and
   correctness, weak on practicality and communication.

   - The new California-centric one emphasizes commercial practicality and communication 
   but doesn’t give a damn about software quality or excellence.
