The talk focuses on the fact that testing does not improve quality: Any system under test does not change its state and therefor cannot improve in quality. Another development cycle is needed to actually change the software and improve quality.
That is very unfortunate. As the person in the team being most passion about quality I am the only one who has no impact? Over the last year we have spent some time with the QAs in ThoughtWorks Germany to evaluate what we actually do and can do to improve quality of a product.
