In order to guide discussion, let's first consider the following brief summaries of each of the authors. Because computers have a built-in individualistic bias, they will not contribute to the socializing goal of education. A school's primary purpose should be educating for socialization rather than for individual problem solving or information access. The computer facilitates only certain kinds of thinking and learning. Both authors seem to assume that the computer is an inherently alienating device.
Postman speaks of alienation from society and from the democratic tradition of public discourse.
For Neill, on the other hand, the issue is alienation from the individual body. The student, in his analysis, begins to live in the world of puzzles and problems, leaving behind the world of emotions and passions. It's clear that neither Postman nor Neill had MOOs in mind when they made these arguments.
