While I don't share Jeff's dire predictions - I think things progress in a nonlinear fashion - his point is well taken. That the economic system will be replaced there is little doubt. That it will need to be more cooperative I also think is inevitable. That social interactions and mores will transform as a result of the above is a certainty.
As the Chinese say: may you live in interesting times!
