The field of computing has always changed rapidly, and it is still doing so.\u00a0 The changes are driven, more than anything else, by Moore\u2019s law.\u00a0 Many people think the pace of change is slowing, or even that because we already have the Internet and Google, there is not much left to do.\u00a0 I hope these papers will convince you that this view is entirely wrong.<\/p>\n
For the last 50 years, new applications of computers have followed a pattern, as one manual activity after another has become automated.\u00a0 In the 1940s, it became possible to automate the calculation of ballistic trajectories and in the 1950s of payrolls and nuclear weapon simulations.\u00a0 By the 1970s, it was possible to create reasonably faithful representations of paper documents on computer screens.\u00a0 In the 1990s, we had the equivalent of a telephone system for data, in the form of the Internet. In the next two decades we will have embodied<\/em> computers, machines that can interact with the physical world.<\/p>\n","protected":false},"excerpt":{"rendered":" This is the transcript of a talk given at the NAE Annual Meeting, October 2002 as an introduction to a seminar on the topic of the title.
