I was less impressed with this presentation by Etienne Wingert than the earlier one. It caused me to think about the format of the very large group presentation such that he could interact less with participants. He also presented a series of concepts that were complex and not broken down to be chewed upon bit by bit as in the earlier presentation. This unfortunately showed me how a very skilled, knowledgable presenter can be stymied by the demands of the presentation such that I got less from it than I might have in a different format. Having "bonded" with him from the earlier presentation, I was willing to give him the benefit of the doubt, but know that students won't if they haven't connected successfully with an instructor's presence earlier.
