When he compares his non-hierarchical theater to traditional 19th century models, he highlights the centralized authority of the conductor, and the position of the royal box. The Akiyosidai performance space (1) has no central node, no axis implying a power structure. It is to be filled collaboratively, with musicians dispersed in the audience so that everyone is close to the music.
The traditional, 19th century social unit was prescribed by the distance feet (ours or horses') could take us. Now our networks are flung across continents and the globe. The 20th century has proven that the social structure of foot traffic is not entirely appropriate for modern scale. Maybe our new scale of activity requires a new format for interaction.
