I think what CBV means by “blending” is not averaging. Each human has an incommensurable, irreducible set of preferences. Instead of extrapolating, which will only diverge, we need to figure out a way we can “live and let live,” and make this agreement coherent such that everybody in a hyperlocal sense sees it as the obvious way to go. Increasing this capability over time yields superintelligence, but all of its components are human-compatible.
