I don't claim to be very knowledgeable about this but it seems like you're bringing up a valid point. In the presenters analysis, he looks for very specific types of bugs when making the claim that static typing only addresses 1-5% of bugs. Your claim is, essentially, his type of analysis undercounts the number of bugs a non statically typed language by creating too heavy handed of filter. Do you have any data to back this up or have links to papers that try and do a better job of counting issues that statically typed languages catch?
