Contemplating IT

I went to the Computer History Museum last week in Mountain View, CA to see the Difference Engine conceived and almost invented by Charles Babbage in the 1830s.   Basically this was a computer run by kinetic energy (a person moving a crank) using sophisticated mechanics to make complex calculations.  Babbage also conceived of the Analytical Engine - a general purpose computer that took the Difference Engine concept to the next level.  

The cost of these systems and the amount of time required to build them were daunting and his personality was so volatile that he alienated the ecosystem required to build them.  He finally gave up and said that "another age must be the judge".  Babbage was a victim of his arrogance and as a result he played a big part in the destruction of his own dream. He also over-promised and under-delivered spending years and years on the project and endless amounts of money. At some point his funding source - which was the British government - terminated the relationship after spending what it would cost to build 22 brand new steam locomotives. Not only did the funding end but so did any good will he had with the British government since they refused to consider further funding of his Analytical Engine - which could have changed the world in deep and profound ways.

This is from the Computer Museum website - "The first complete Babbage Engine was completed in London in 2002, 153 years after it was designed. Difference Engine No. 2, built faithfully to the original drawings, consists of 8,000 parts, weighs five tons, and measures 11 feet long."  And it works.

It was very cool to see the thing in action - all of the little widgets rotating and gyrating making clinking and clanking noises.  I highly recommend visiting if you are in the area.  (Btw - the photo was taken by a very nice girl named Sara. I left my camera back at the hotel and asked Sara if she could take one and email it to me. She did a great job too! She got Babbage in the background, the Difference Engine and me all in the frame. Well done Sara and thank you!)

What would have the world have been like if the computer was invented over 120 years earlier? Would there be an IBM? Intel? Microsoft? Apple? VMware? It was so close to happening, albeit in a different manifestation but the value would be very similar. Certainly the world as we know it would be measurably different - a compelling pun to consider when contemplating the Difference Engine.
