Prof. Alan Kay Viewpoints Research Institute 1209 Grand Central Avenue Glendale, CA, USA, 91201 "The Computer Revolution Hasn't Happened Yet" The research community that invented the personal computer and the Internet were inspired and guided by the transformative nature of the printing press. Although it looked as if it was just automating hand copied document production, the combination of being able to hold new kinds of arguments, being able to massively transmit those arguments with a much higher probability of finding receptive minds, and that it could vastly aid in the teaching of how to use itself, allowed the printing press to completely transform human thought and "how thought was thought about". This took 150 years, but the change was qualitative. It was clear that the same possibilities obtained for the personal computer and Internet. The easy part would be covering the Earth and copying and transmitting already existing media. The hard (and much longer part) would be to gradually get the general public to learn what was new and important: that the computer brings forth entirely new ways to represent ideas, expose and exhibit them, and to argue about them. Most of the sciences have started to undergo the transformations in thought brought by computing, but most of the general (and especially voting) public has not. The printing press was invented in the mid-15th century, but its revolution happened in the 17th. The computer was invented in the mid-20th century and its real revolution is yet to happen. This talk will try to show what that revolution will be like when it happens, and why it will be at least as big as the printing revolution.
