Loving the video. I have a couple of volumes of TAOCP. Even though I am not in CS, the series is so well known and so respected that it is a must-have. I'll periodically leaf through some pages and have a hard time grasping how much work he must have put in, how many papers he must have read - good, bad, and indifferent - to extract the best and put them all in context. No wonder he gave up email before most people even heard of it and decades before it became cool. I saw him many times on the Stanford campus in the late 1980s when I was a grad student in chemistry. Never went up to say hello and to thank him for TeX.
