The book introduces the born of computer and Internet. I really loved the idea of collaboration between humans and machines. Although the book did not provide technical detail about how certain devices or machines work, it got me interested and I searched the answer online. The human history is changed and I do not think we can change it back. Even though the ideas and methods are rigorously expressed, the term evolution can still apply to this kind of change. It makes me wonder how the world is changing and how the future will be.
