One of the first times I heard him speak was in late 2014 and he was essentially arguing for all the same things that he argues now: "I don't know how the tech community is going to do it, but they're smart, and they can build in secure access for law enforcement". He still completely ignores the national security implications of such a precedent, and he also ignores the fact that, over and over again, crypto experts are telling him that the community has enough trouble building secure systems at the moment, and adding access to third parties is likely to exponentially weaken system security.
