"Each prior “intelligence explosion” was not an upgrade to individual cognitive hardware, but the emergence of a new, socially aggregated unit of cognition. Primate intelligence scaled with social group size, not habitat difficulty. Human language created what Michael Tomasello calls the “cultural ratchet”: knowledge accumulating across generations without any individual requirement to reconstruct the whole. Writing, law, and bureaucracy externalized social intelligence into infrastructure, institutions that coordinate across longer time horizons than any participant within them. A Sumerian scribe running a grain accounting system did not comprehend its macroeconomic function; the system was functionally more intelligent than he was.
AI extends this sequence. Large language models are trained on the accumulated output of human social cognition—the cultural ratchet made computationally active, every parameter a compressed residue of communicative exchange. What migrates into silicon is not abstract reasoning but social intelligence in externalized form, encountering itself on a new substrate.
If intelligence is inherently social, then the path to more powerful AI runs not through building a single colossal oracle but through composing richer social systems—and these systems will be hybrid. We have entered the era of human-AI centaurs: composite actors that are neither purely human nor purely machine. Centaur actors can take many forms and inhabit many different roles. Each one of us may move in and out of diverse ensembles many times a day: one human directing many AI agents; one AI serving many humans; many humans and many AIs collaborating in shifting configurations."
