I got a bit out of them, but even as a veteran C++11 user I found quite a few pieces lacking in motivation (i.e. I could read the text but not grasp the reason for its existence). And your slide with "I actually wrote this code" says C++14 will reject the bad code, but doesn't mention how or why.

It's clear that you put thought into having real content in your slides, as opposed to some (including from this group) which are mostly funny pictures used as a sort of ice-breaker while we can only imagine the presenter talked about technical topics on stage. But the reader of your slides is still left far behind the attendee of your talk.
