This is probably something I'd find interesting and enjoyable but: the video doesn't load (for whatever reason), the slides have no "Next" button (for whatever reason), and there is no plain text transcript... so I guess I'll have to skip it.
Seriously, when you prepare a long talk, surely you write the script beforehand, right? Then upload it (in a text format), please! Also, there is nothing wrong with PDF slides: those don't look too great, but at least they don't usually have problem with scrolling.
