“32 years ago in 1975 I was one of several lucky Americans who were invited to Pisa to help celebrate 20 years of computer science in Italy. I presented a paper on the first fruits of our attempts to invent personal computing at Xerox PARC. Over the years I somehow lost that paper, but Porfessor Attardi, who was more organized than I, was able to locate his copy and it has been republished as part of our cderemonies today. It is tempting in this talk to go through that paper and see how this past work influenced today.” (Alan Kay – VRI)
