Just as eusocial creatures like termites create pheromone infused mudballs which evolve into pillars, arches, chambers, etc., a single individual can maintain a collection of notes (a commonplace book, a zettelkasten) which contains memetic seeds of ideas (highly interesting to at least themselves). Working with this collection over time and continuing to add to it, modify it, link to it, and expand it will create a complex living community of thoughts and ideas.
Over time this complexity involves to create new ideas, new structures, new insights.
Allowing this pattern to move from a single person and note collection to multiple people and multiple collections will tend to compound this effect and accelerate it, particularly with digital tools and modern high speed communication methods.
(Naturally the key is to prevent outside selfish interests from co-opting this behavior, eg. corporate social media.)
