There seems to be parallel in Two Selection by M. McLuhan and Computer Lib by Theodore Nelson. Both consider computer as media form. For McLuhan, media overwhelm the importance of content, where Nelson resound what McLuhan’s idea of media by redesigning the media. Nelson’s compare the media we lived in with that fish living in the water.

In Nelson’s Dream machine he presented his observation how the computer professionals has at most part kept the sacred know how to themselves where the public is kept at bay.
Since I don’t know how it was really in those days about the evolution of computer, by reading his writing I sensed that during those days it must be pretty confusing for general public to learn about computer. Then, the view on how computer should be taught in schools. I agree that students should be allowed to discover the learning on their own. There is nothing wrong with that at all. However, there are a couple of points that I think is missing from that, one is the rudimentary is just as important as creativity. Once the rudimentary is clear then the exploration can take place this occur in any discipline. Another factor is time. If we don’t have to be concern about sequence of learning, then each students will discover on his or her own about certain concept about computer. Then it will take different amount of time for students with varying aptitude and curiosity to learn. Suppose some student manage to learn 4 items in the semester, and other learn one item for the entire semester, would this be considered learning? Does it matter the amount of material learn per each individual students by the specific time? If each student does not need to be concern about time then the definition of learning would be- care-free and creative. Nothing is wrong with that either. Since we are driven by time everyday we live our live, it is not feasible I don’t think to do it without some sort of sequence. Nelson is a visionary no doubt.
