How does Game B evolve?

Continuing this post, I'm looking over this recent document on the nature of Game B. I like this from the section "how does Game B evolve?":

"The modus operandi is not writing down the new rules of the world in some manifesto. The modus operandi is experimenting and prototyping and discovering what you didn't know and correcting and evolving and... emerging. This produces elegant outcomes. Formulas don't work and they have terrible unintended consequences, e.g. communism. We shouldn't imagine we have the answer."
