This is a very good piece. Here is the closing bit:
In his paper Robert Gordon talks about the huge value gained from “one-time” events, such as the one-time (first and last) move of a large proportion of women into the workforce. This new gain happens only once (assuming they remain). In this computer-internet economy we are experiencing a one-time gain from a huge one-time event. This is the first and only time a planet will get wired up into a global network. We are alive at this critical moment in history, and we are just at the beginning of the beginning of the many developments that will erupt because of this shift.
Cory Doctorow has interesting comments.
