What is actually the worst possible outcome is to have one strategy, religion, or culture adopted by everyone.
This is the point I disagree with. I think we both agree that the optimal way to increase degrees of freedom for individuals is to allow and enable instead of controlling. A universal strategy is an essential foundation that
enables freedom. Without that, we have the situation that is developing now with varying viewpoints where some sets are progressing toward destruction and others are being dragged into declining entropy. Competition can take place when there is room for growth but on a globally saturated scale, nobody wins.
Reproductive strategy is likely to become essentially irrelevant for humanity, possibly within our lifetimes. It seems inevitable that our existing biological bodies will give way to different forms that will carry us off-planet. At that point, allowing and enabling all individuals to thrive in a constructive environment becomes paramount. What then is the protocol that keeps that freedom from becoming destructive? Of course, my thinking is that the protocol is outlined in the Christian bible.
