Some Alan Kay Quotes

You've probably heard Alan Kay's famous quote "The best way to predict the future is to invent it." I was looking for a reference for this, when I came across some more quotes from him, some of which I thought were pretty good:

"It [the computer] is the first metamedium, and as such it has degrees of freedom for representation and expression never before encountered and as yet barely investigated."

and on similar lines

"It (the computer) is a medium that can dynamically simulate the details of any other medium, including media that cannot exist physically. It is not a tool, although it can act like many tools."

(though I disagree that this means it isn't a tool).
