You have a point in that Vinge portrays outward migration into higher Zones, with all their unexplained advantages including computational advantage, as part of the process by which a civilization of natural intelligences evolves to the point of producing a superintelligence. (For those who haven’t seen the book, the Zones are concentric regions of the galaxy, in which the further out you go, the more advanced the technology that is possible, including superintelligence and faster-than-light travel.)
