I'm a bit unsure about this book. It's on a subject that's really interesting philosophically and that I'm curious about as a neuroscience fan. I'm sure I learned things from it and it feels like the author is really knowledgeable about the subject, but the book ended on a few things I disagreed with and that kind of ruined the impression of the whole thing.
Mostly I felt like the author explained the AI threat, and then dismissed it because it's unlikely for AI to have gained consciousness in the authors view, despite just having explained the difference between consciousness and intelligence, and, in my opinion, the threat from AI comes from intelligence, consciousness not required. As a minor complaint is the very ending of the book that sort of allows for some sort of mysticism, again, despite having spent almost the entire book explaining how consciousness arises from our meat brains.
And maybe I'm not a good enough listener, or maybe because of these last two disagreements, I don't feel like I understood quite clearly what are statements about consciousness that the author feels derives from current research and what are open questions or the authors intuitions.
