It's a hacker-themed fairtale for computer illiterate, basically. I had a non-techy friend borrow the book and they too couldn't finish it, because it was just way over acceptable believability limits even for them.
Almost all the tech (Self driving cars, distributed systems, daemons that can self replicate (viruses), collaborative systems, a Darknet all exist in some form or the other today! Is it fantasy? Duh!
Is it a fun read for someone who works building these exact systems fora living? Definitely!
Either way - a fun read and a good book to re-visit. One of the few that I read every few years or so...
But it was still a fantastic novel, I loved reading it, and will probably re-read it again and again.
I don't think it address it enough; it made it more plausible by admitting that it can't be completely autonomous, but I'm not entirely sold. Having said that, I still love the series, much like I love any fantasy novel :P
Don't let this guy stop you from reading these awesome books! I recently re-read it, and the first few chapters are pretty tough because it lays out all the tech premises. Stick with it. The plot will keep you engaged, and the storytelling is supurb
