The key change computers have wrought is the condensation of human knowledge and information into machines. The two fundamental effects of that are true automation, and globalization. Less and less human labor is required to make the things we use. Capitalism is essentially a set of relationships in which most people work for corporations in exchange for money to buy goods. Any major reduction in needed labor breaks that relationship by separating these people from the money required to participate in a culture based on money exchange.
Globalization is now basic to our existence.
This worldwide crisis is just beginning to get going in the United States. They cry out, not to retrieve the past, or to repair or reform the system, but for a quest toward a new society to match our tools, and this change of tools is on the order of the invention of fire. This demands a social structure that allows all humans full access to all the resources of the society. We need to stop debating how many will be left behind and start debating how to leave no one behind. I assert that the very same phenomenon that is rendering life an unworkable nightmare for many, implies a society based on cooperation and giving things away for free.
