Published expectation, not a measured outcome.
No matched theme yet
What may hold
Holds when the know-how lives in physical operations; erodes once it is written down where agents can read it.
Associations are not causal evidence. Zero matched works is a coverage gap, not evidence against this moat. Literature activity is not market performance.
AI durability is an expectation; no moat type has yet been shown to predict profit persistence in the AI era. Not investment advice.
