The changes we collectively seek always starts when the damage collectively sustained reaches a saturation point.
I don't think we've reached that stage yet but I do believe we will eventually. I think that it's inevitable we will, even if that tipping point occurs after the cataclysmic occurs first. There have been many times in human history where we failed to reverse course and end the campaigns that lead to catastrophic losses. What is also true is that we collectively build something new on top of the ashes of the old ways.
The question remains: will the new construct serve our best interests or will it repeat the mistakes of old guard?
