https://web.archive.org/web/20050207105550/http://www.rushkoff.com/cyberia/index.htmlI'd give you the pdf (which can be found easily via a quick search), but lainchan seems not to be cooperating with me today.
The book really captures the optimism of 90s cyber subcultures. It gives a very romanticized view of the potential for future technologies. It was this book and Serial Experiments Lain that really got me interested in computers. I'd say that looking back, there were definitely some cultish/pseudo-religious undertones related to computer worship and drug/rave culture that seems somewhat farfetched or naiive today. I'd say the best part of the book is Rushkoff's journalistic approach (much like that of Hunter S. Thompson or Stephen Levy). All in all, a fun read and gives a great perspective of a 90s subculture, but I'd take everything at face value when applying some of the concepts of the time to this day and age. Here is the full book in pdf for those interested.
