I find it almost unbelivable how the author who wrote Snow Crash, which is one of the greatest books I ever read, could also write something like this. The sole explanation that I can find is that it seems that authors, like programmers, often fail miserably with their second project, as they loose the focus on what is important and what not in their writing.This is what I think happened here. The characters are schematic, the action also schematic, the plot inexistent. Nothing really happens in this book. The focus is on the effects of nanotechnology on the world - but in my opinion a single-sided boring view (for example, in the whole book there are no computers or AIs).The author makes some presumtions about the future which seem very wrong - but this would not be a problem if the book wasn't so badly written!
