From all the readings so far as well as personal experience, people do not like to put much effort into stuff. Throughout history people have come up with new ways to make our lives easier. We built a wheel that we could attach to wagons in order to pull a lot of stuff at the same time and not have to carry it all. We built calculators to make counting easier. These are just examples that people have come up with over time to make our lives easier. I think the same goes with the shift from computers, looking like huge monstrosities, to being able to take almost no space away. We have had computers for some time but they were too big and too expensive for “regular” people to use. Even though they were big, these types of computers have provided some usefulness such as the tabulating machine created by Herman Hollerith. This machine cut down the time it used the U.S. census bureau to count all the people living in the U.S. Therefore one of the reason I believe had an effect on the intellectual leap was that people were continuously looking to improve and easing their lives and these computers have shown that they can do that.
I think the other big reason why there was such a shift was because of the time computers became known and usable by the general public. The demand for small personal computers started to occur during the 1970′s after the war. People got “sick” of the government and hiding information from them that they wanted to be part of technology as well. Campbell-Kelly and Aspray (1996) mentioned the rise of Computer Liberation. People that were part of this movement believed that computers should be affordable and accessible to the general public. In order for this to happen computers needed to become smaller and easier to handle for someone who does not know a lot about technology.
Lastly I think that one of the reasons computers advanced and became smaller was for capitalism. One company started a new product, such as the calculator and then other companies thought it was a good and brilliant idea so they decided to be part of this new era as well. This created competition between these companies and the demand to stand out. But the only ways to stand out was through the creation of new and better technology which in the end led to personal computers. This in turn also allowed for better technology since you had the ability to communicate with others, share ideas and have more access to material that is needed to built and advance the technology.
