content: This book has received great acclaims for the many ideas and concepts presented in it — if you trust the raves on the cover. As I see it there are mainly two ideas: 1) convert all available matter to "computronium" and 2) upload yourself, your pets and your companies. What you get is basically an intersolar internet with "ghosts in the machine".Now try to add a plot to this... Well here is where it fails. The plot is basically non-existing and reading about the same "great ideas" over and over again gets boring after a while.This book was a disappointment after having read "Singularity Sky " and "Iron Sunrise" by the same author. Exciting books with both ideas and a plot.
