A Fire Upon the Deep, Chapter 1165: ---

Chapter 1165 of *A Fire Upon the Deep* reads like marginalia Vinge wrote for himself — a species brief on the Dirokime that never earns a dramatic scene in the novel proper. But it contains an inversion that the rest of the book spends hundreds of pages circling without stating. The Tines are the novel's celebrated thought experiment: individual minds forming a group consciousness, each member replaceable, the pack-self persisting through component death. The Dirokime flip this exactly — brothers who function as a reproductive and operational unit, an ancient species now dormant after "extensive transcend seeding," their identity distributed not across bodies sharing one mind but across one lineage sharing one purpose. The chapter's offhand mention that some Dirokime might treat commercial security as a joke suggests a species so old it has passed through seriousness into play — the attitude of a civilization that has already been a Power and come back down. That Vinge flags humor as a species-level trait, alongside reproductive strategy and deep history, is the quietly radical move: comedy as evolutionary artifact, not cultural choice.
