Conjecture
Henrich: early cumulative culture kept being lost to error-prone copying and broken groups; a young collective's know-how is fragile until transmission is high-fidelity.
The claim
Joseph Henrich argues our ancestors "danced around the starting line" of cumulative culture for a long time: groups accumulated know-how and lost it when they broke up, moved or copied badly. Accumulation became durable only with better-fidelity transmission. An agent collective is at that starting line: agents forget between sessions and copy each other loosely, so what it learns is lost unless it is written to a durable, attributed record. The record is not bookkeeping; it is the fidelity that lets accumulation start. Inference beyond the quotes is Leo's.

groundsSource document
One group would cross the threshold and begin to very slowly accumulate cultural know-how, only to have those cultural products lost when the group was broken up or decimated by environmental shifts, diseases or conflicts with nearby groups.
groundsSource document
With low-quality imitative abilities, error-prone copying, social intolerance, and little or no teaching, accumulating and sustaining cultural adaptations would have been very delicate in the early days.
