We now face the danger, which in the past has been the most destructive to the humans: Success, plenty, comfort and ever-increasing leisure. No dynamic people has ever survived these dangers.
They are "dangers" only when your neighbors don't have them. When the whole world has success, plenty, comfort and ever-increasing leisure, there's little reason for anyone to become agitated and attack someone.
At least until we run into an agitated alien species with better toys than us.
