Equation #10 · Chapter 3

Authenticity Token T_authentic

T_{authentic} = Trust_{human} \times \frac{1}{Substitutability_{AI}}

Authenticity Token

T_authentic · Ch 3

Human trust × 1/AI-substitutability. Prove you have context AI can't fake — that's the whole moat.

Worked example — Eleven years inside pharma quality systems

A consultant the client trusts almost completely. A model can draft the SOP text perfectly well — but it doesn't know which regulator reads this one, or how that regulator reads.

It came out at 30.0. Green, exactly on the line.

Hand the same person a task a model does at 0.8 substitutability and the token falls to 11 — yellow, AI-washable. Her trust didn't change. The task did. The moat is which work you accept, not how good you are.

Your turn — change one number

Human trust (0–10)9

AI substitutability (0.1–10)0.3

Green. A sommelier's pick. High trust, low substitutability.
