In this chapter Nicholas Carr explains that how technology can help human’s life a lot more easier. Carr points out that our brain has long-term, short-term and working memory, he states our brain turn into simple signal processing units, quick shepherding information into consciousnesses and then back out again.Therefore, our, it means that brains change the response by using the internet. There is a research experiment from the chapter that can prove that the working memory will be effects by reading different type of documents. There is one group of people is reading hypertext and the other group of people is reading the text documents. The hypertext reader is easy to lost the topic and they couldn’t remember what they had and had not read. However, the paper document outperformed the hypertext group. As result,  people who read the text document can remember more than the hypertext one. Jakob Nielsen a long time consultant of web pages who has been studying on people online reading, he mentioned when people read on the internet, they actually don’t read anything. Carr also points out that the working memory from our brain that able to hold a very small amount of information. However, when people who browsing, scanning, and reading from the internet, the working memory couldn’t remember anything after all. There is other statics that showed the time of people who is reading on the internet, they read the words as fast as they can, but at the end of reading, on one can remember what is the article about. Also, when people do the hypertext reading, they have to use the  mouse to click for next page, after that they couldn’t remember what is topic about. There are expert’s research, experiment and statics proved Carr’s point of view.
