Some form of narrative repository has been in
existence for a long time, and people have found a variety of ways of sharing
knowledge in order to build on earlier experience, eliminate costly redundancies,
and avoid making at least the same mistakes again. For example, knowledge
sharing often took the form of town meetings, workshops, seminars, and
mentoring sessions. The primary “technology” used to transfer knowledge consisted
of the people themselves. Indeed, much of our cultural legacy stems from
the migration of different peoples across continents.
