Upon further inspection of Charles Babbage's story is that he was a product of the industrial revolution and like many key figures in that time strived to improve the way work was done. Making systems less prone to error or have increased efficiency is part of this time period. The problem that lead to the difference engine was that of the fact that previously the only way to do a calculation was that you had to do it yourself. Things like the Abacus did help but for the complicated calculations needed for scientific research and navigation meant that many mistakes could be made.
If you want to find out ore about Babbage this article is quite nice:

Babbage sought to remove this problem and make things better. This attitude of improvement is the story of computing as all the time computers are getting faster, smaller and sleeker. with more possible programs. This changes many of things in our lives by allowing new medical systems or scientific advancements that lead to faster cars, new cheaper ways of making pretty much everything we have and then allowing us to create new inventions.
Anyway lets stick to the development of computers...
Mechanical computers were built after Babbage's death. The next major steps in computing were made in the run-up to and during the second world war as electro-mechanical and electric computers were used to crack codes or perform calculations for logistics. The Colossus was one such machine made by the allies to break coded messages sent by the axis.
After the war computers were being used more and more by businesses and governments to do many different tasks.Companies like IBM made it that computers were a part of the system. The next major change was that of computers being made smaller. As technology improved and more complex machines could be made using cheaper materials the size of the machines decreased but they still increased in power. Many computer companies started form creating personalized computers for the new expanding market that moved computers from the workplace to the home. The ZX Spectrum is a good example of one of these new computers for the home.
