“We would like to collect and disseminate the interesting thoughts and ideas of Dr. Alan Kay. The Talks by Alan Kay page lists accessible movies, documents, and (soon) running simulations and demos linked with the talks and documents.”— Viewpoints Intelligent Archive
As for my own transcripts of Alan Kay's various talks—the lengthier one being The Computer Revolution Hasn't Happened Yet—feel free to copy them all. No attribution necessary. Copy, paste, edit, clean up, spell correct. The lengthier talk has some helpful comments with corrections.
