I love jumping spiders, so this book is like a dream come true for me. The book deals with various transhumanist ideas, particularly increasing the intelligence of non-human animals, uploading a human mind into an AI, and reaching for immortality via technology. It handles these ideas in a very even-handed way, and is not pushing any kind of ideological agenda. It's a very enjoyable read that works well as a fun adventure but also gives you a lot to chew on. Highly recommended.
