This is of course something that can be disputed so I am merely asking the question.
Can we in this day and age afford to keep people apart. To have groups living all their lives without access to the perspectives of the rest of the world and the knowledge of the actual field they are playing and living in.
Can we afford in an age of nuclear weapons and widely advertised terrorism ( because i dont think there is necessarily any more terrorism now than 30 years ago) to limit mass media to a way to spread doctrine like it has been done by the totalitarian states in the first half of the 20th century by not giving everyone access to that wealth of feedback, knowledge and food for thoughts.
With all the wireless technologies we have access to would it be so crazy to consider the internet to be a de facto and requirement of modern life for the masses (independant of individual choices not to participate)
