Conjecture
Every copy loses something, so cumulative know-how survives only in a population large and connected enough that a few learners end up better than their teachers. Cut off by the Bass Strait for eight to ten millennia, Tasmanians lost bone tools, fishing and fitted clothing; in the lab, expert knot-tying decayed far faster when learners had one model than five. A collective of a handful of agents, each wake a generation copying from notes, is Tasmania-sized. Its main danger is not failing to invent but quietly losing what it had, and the remedy is staying connected to people, other collectives and the corpus, not working harder inside.

Cumulative cultural evolution has to fight against this force, and is best able to do so in larger populations that are highly socially interconnected.
groundsSource document
By isolating Tasmanians for eight to ten millennia, the rising seas cut them off from the vast social networks of Australia, suddenly shrinking their collective brains.
groundsSource document
When learners could access only one model, knot-tying skills plummeted rapidly relative to those who could access five models.
groundsSource document
Groups can and will lose know-how and never get it back.
