To be clear, I think reading is awesome and not replaceable by videos. It compresses information wonderfully, so it's inconceivable that a video could ever replace a good academic book.
Also, the ease of jumping in and out at any point, and bookmarking points, is much better than with video.
The irony is that - aside from the lower cost of production - novels are the genre of book where film & video most often equals and maybe surpasses text.
