The difference engine was to carry out a specific task - much like the earliest electronic computers. The analytical engine was to have been a general purpose machine. A similar inspiration worked in those who built the first general purpose electronic computers. In that sense we may be said to have solved Babbage's problem over again, but we didn't lose all that much by it. Received on Wed Jun 28 2006 - 06:15:24 CEST
