A person's true moat is often not "what you have already shown," but rather the fact that others can never be sure how much you haven't revealed yet. They usually understand the rhythm as: not firing all the bullets at once, not disclosing all the underlying logic, not allowing others to form a final definition, always reserving some unexplored space. That is also why: mystery, at its core, is not about being deliberately obscure. It's about "the boundary of capability being unpredictable."
