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.
The greater danger for most of us lies not in setting our aim too high and falling short, but in setting our aim too low, and achieving our mark.
