A lot of cool ideas, but at least 100 pages too long. The third acts slogs along to a resolution which is on a different frequency than the rest of the novel.

But it is a ton of fun to read a book set 10 years from now, but written 30 years ago. So quaint are the predicitions of the internet as a benevolent force of education and humans getting their act together to combat climate change, but sci-fi *is* the genre of hope! What are we predicting now that will seem absurd in 50 years?
