Speculation on Gershenfeld and Kahn
In the article by Gershenfeld, he talks about a personal fabricator, which is "a machine that makes machines." He talks about a class that he tought called "How to make Almost Anything" and how he observed four surprises from his students, which were:
1. The amount of interest from students
2. How they were motivated to take the class in order to make things they always wanted
3. What the students acomplished
4. How the students learned
He also talks about how he believes the personal fabricator will be in almost every home in the near future. He then talks about how engineering in Space and Time is becoming cheap.
The article by Kahn talks about Silence and Light. He says that "Silence is a void, not a place but the desire." He also talks about how "light allows people to see and experience a structure and without light, there is no architecture." He goes on to talk about how cities are measured by their Universities and how things are expressed.
The two articles are alike the Kahn articles talks about how How cities are measured by their universities and the whole point of the Gershenfeld article is the class, "How to Make Almost Anything" and how things change as technologies change. Another thing that links the two articlse is the article by Kahn talks about how without light there would be no depth or architecture. So basically without light, there would be no need for the personal fabricator that Gershenfeld talks about in his article because humans wouldn't be able to see anything.
