I doubt the author would have any issue with a video of his lectures being online, along with the accompanying slideshow. His issues is with trying to cram all content into the slideshow and simultaneously present said content to a live audience. The slideshow should act as a visual aid to great teaching, rather than trying to replace it. I liked the idea that the slideshow alone should be nonsensical.
