My characterization of a good Alan Kay keynote is something to make everyone in the audience irritated :)
But in this short (2.5 minute) excerpt from an ACM conference talk, Kay really bashes Dijkstra.
Several years ago SD&M had a Software Pioneers conference. The speakers list was incredible, but I can't get the videos to work anymore. But you can watch Kay's talk, and Dijkstra's talk here and here.
Bonus video: Senator Obama fielding a question about sorting integers at Google.
