Altruism, trust, and cooperation often emerge from acts and choices that seem completely self-interested.
Heck, cooperation is a survival strategy that came out of evolution. It exists outside of humans. It doesn’t need to come from human intent.
It feels weird to me that people think they can intelligently design cooperative societies and groups. You can try, but there’s always going to be trade offs between individuals and the group.
In this moment, individuals are in a place where they can avoid many of those trade offs and costs. I think this is generally positive considering my own experience of costly kinship groups. But I can see why others disagree.
