It changes how computer scientists view computer science. How We Think begins by giving an overview that the remainder of the paper will discuss the ramifications of the shift in the computational metaphor, using the example of a navigation-based mobile robot. Stein then discusses briefly her own experiences in her research group and the problems they encountered. The fifth topic ends by asking three questions that shall be in each of the following three topics. Stein then proceeds to describe how the robot behaves and how each sensor responds to their environment.
Robots are hands-on.
Stein gives an account of concurrency and how it is used in every day society amongst people and in the computing world. A robot is not this kind of beast. Stein then describes the scenario of the robot reaching a corner and how the students had not anticipated this event. Stein gives plausible solutions to overcome this problem based on laboratory experiments that where carried out. Stein proposes to validate new ways of thinking, such as the Blue technique and Turkle's silenced tinkerers.
