The learning theorist who proved that knowledge lives in communities, not individuals—and whose concept of the community of practice now illuminates exactly what the solo AI builder gains in productivity and quietly loses in formation.
Étienne Wenger arrived at the study of learning by way of disillusionment. In 1987 he published a comprehensive survey of
artificial intelligence and tutoring systems, the most rigorous account available of machines built to transmit knowledge to learners. The experience of writing that book convinced him the entire enterprise rested on a false premise. Learning, he came to believe, was not the acquisition of knowledge by an individual mind. It was the transformation of participation in a social practice—and that shift, from acquisition to participation, is the lens through which every question the AI age raises must now be refracted. His partnership with anthropologist

Situated Learning (1991) and the concept of
legitimate peripheral participation; his solo masterwork
Communities of Practice (1998) built the full theoretical structure. Wenger gives
