Query: A Collage of Previous Work?

This is a simplistic, out of date treatment of a diverse and rapidly changing field. It is a disappoint that Bar Yam failed to capture the depth of the field, instead offering a cursory look at, mostly, classical examples in which Bar Yam did not take part. I would prefer, instead, to see a leader in the field write such a text, such that I could be assured that details that were omitted were less relevant, not simply forgotten.
