Excellent post! I think it ties in very well to my recent research on human-based stigmergic AI, inspired by your work. Perhaps stigmergy is a personal preference optimization function and it is in every individual's interest to improve that optimization function via a feedback loop, resulting in a recursively self-improving intelligent network.
