Lecture2:is the picture that this video paints too bright and optimistic? Does it leave anything out?

yes, I think. It is because the video type only suggest the good points of the computer technologies, such as it fastern the information flow, lessen the limitations in storing the knowledge and etc. But it doesn't aware of the danger of what kind of information is uploaded and the accuracy of that information. We, students need to concern both of the pros and cons of the computer technologies.
