We have entered an age of disruption. Financial collapse, climate change, resource depletion, and a growing gap between rich and poor are but a few of the signs.

They highlight the paradox of progress: Though modern systems have given us new capabilities, they've become vulnerable to surprising meltdowns - and even to corruption and misconduct.
