This was still great, but somehow I didn't like it as much as the first book. I wouldn't have minded if it had been about 100 pages shorter, especially in the middle. I'm complaining on a high level here, though. I'm giving it 4.7 stars. 
 The last third was pretty amazing, offering lots of ideas that felt new and fresh to me. Finally a series of books that is not predictable, and which gives you something to think about. I also enjoyed very much that you can tell that the author is neither US American nor European. Especially since it's not about people, but ideas and science. I'm so tired of the same way of thinking.
