to really get meat, he would have needed a lot more time than he had allotted to him. i think if anything you could say that he tried to cover to much in the time he had.

The talk stops at ~19 minutes, but there were many questions asked and answered in the Q&A segment. That doesn't help in the meat department for that video however.

I would love to give that same talk, but extend it to 90 minutes. I suppose it still wouldn't reach the depth that such a talk requires, but it would be more satisfying.
