Query: Virtually incomprehensible

This book is extremely heavy on the esoteric, philosophical lingo. As a virtual environment systems designer, I found it to be essentially useless. My guess is that it would be of value only to academicians and others not directly involved in the technological aspects of VE and other digital domains. Although I suspect there might have been some useful stuff here, the writing is too tangled to unravel. If you speak academese, you might fare better than I did.
