Personal Intelligence
Personal World Models: Toward Human-Centric Personal Intelligence Systems
The dominant paradigm in AI optimizes for machine-side intelligence: scale, benchmark performance, agentic capability. This framing is correct for many objectives and incorrect for one — systems designed to live with a specific human over years. For such systems, the central missing architecture is not more intelligence, but a different kind of structure: one that encodes not how the world generally behaves, but what the world specifically means to this user, in their specific history, with their specific relationships.
- Formally distinguishes the personal world model from user profiling, persistent LLM memory, and graph RAG — structural differences, not cosmetic ones.
- Introduces three-layer knowledge separation: ontology primitives, common-sense priors, and personal meaning commitments — user-authorized, provenance-tagged, reversible.
- Derives continuous engagement (no session boundaries) as a necessary architectural consequence of coherence constraints, not a product feature.
- Introduces constitutional continuity: an alignment approach for systems that accompany a human life across years, during which values genuinely evolve.
