AHI shifts the target from machine autonomy to human capability
AI-augmented human intelligence (AHI) is the paper’s central proposal: measure how much intelligence a system enables in a particular person, alongside how much a machine can do alone. The opening examples are concrete failures of access—a researcher forgets a published result or cannot retrieve her own reasoning when making a decision. The proposed target is a person whose memory, senses, and judgment are coupled to AI.
The paper calls the system a cognitive symbiont: a lifelong, embedded, real-time, private, low-friction, proactive companion. It should sense through external devices, preserve context across years, model the person’s situation and mind, and join their thinking at a useful moment. The authors distinguish this from an agent that merely completes tasks on someone’s behalf.
The most specific technical concept is the cognitive gap: the difference between what a person could bring to a situation and what they can hold in working memory. The paper organizes the system around a symbiosis loop—sensing, keeping, understanding, living alongside, acting for, thinking with, and growing—within a personal runtime and a trust boundary. It presents this as a conceptual framework, not a tested algorithm.
