Is there an overview of "Alan Kay's idea of computing"? I've had a period where I was deeply interested in reading and listening to any of his ideas and talks, but I've never spent any time with the information, other than just consuming some of his ideas. I have some vague ideas about what his ideas are, and where he thinks we're still lagging behind, but I have no idea what "Alan Kay's idea of computing" is supposed to be. Unless, are you talking about his idea of objects as the smallest abstraction of computers, giving each object something akin to an ip-address; where programming happens by wiring together these objects?
