Nadella frames the AI-era firm as accumulating two distinct stocks: human capital (“the knowledge, judgment, relationships, ingenuity, and pattern recognition of its people”) and token capital (“the firm’s AI capability it builds and owns”). His non-obvious claim is that these are complements, not substitutes — “human capital does not become less valuable as token capital grows. It only becomes more valuable!” Human agency is the driver of token-capital growth: humans set ambitious goals, connect dots across domains, and recognize the patterns that matter, because “without human direction, you have compute running in circles.”
This is the same direction as AI automation amplifies demand for expert human judgment rather than replacing it — automation raises the value of expert judgment rather than erasing it — and it explains why the durable move is to Don't be the discriminator — be the patron, not the judge rather than reduce humans to selecting from AI output. The two capitals only compound when the firm owns the surface where they meet, which is why The system of work is the moat, not the model — the model is fungible underneath and the firm’s accumulated judgment outlast any single model generation.
