Any real change implies the breakup of the world as one has always known it, the loss of all that gave one an identity, the end of safety.
Just because it is too late for modern societies to be maintained, does not mean it is too late for influencing the future. Just because it might be too late to significantly influence that future, does not mean it is too late to learn how to participate less in destructive or delusional behaviours.
