Weirdly, I and at least a few others based on the YouTube comments, saw the presentation pop up in our YouTube suggestions in the last few days and at least I watched the presentation a few days ago. Wonder if there’s any connection between its recent resurgence and this Q&A getting uploaded now.

Also gotta wonder (as John does) where this came from. I assume Apple’s archival library, but who got it out of there and why now.
