I never met Winston when he was still alive, sadly, but I first encountered his work when I was still in high school, learning CommonLISP from his AI book.

Every time I am sitting in the audience of a talk where someone uses overcrowded PowerPoint slides with small fonts and goes through tables of numbers that no-one in the audience can read, mumbling quietly or rushing nervously through their material, long having lost most of the audience, I feel like sending the presenters the link to this timeless masterpiece (happens at least a few dozen times per year).

It has also made me a better teacher in the lecture hall, and appreciate using chalk more, and slides less.

This clip is worth watching again every couple of years, which I do, out of enjoyment and to refresh my memory (reminds me I still need to procure some cool props for my upcoming AI1 lecture in October...).
