This is the first thing that he says during his keynote:
"So, in the next couple of days you're going to hear a lot about the latest and greatest in C++, You're going to hear a lot about advanced techniques and new features. And I decided that in the keynote I couldn't go too much into that, so I'm going to do the opposite. I'm going to try and focus on what is the essence of C++. What is it that has been constant over the decades and what it is that that keeps C++ alive and kicking."
It was clearly framed as a history lesson about C++'s strengths, so I think it is a bit disingenuous to claim he was teaching resource management to a crowd of advanced C++ programmers.
