Rough in some places but smart systems thinking/long-term thinking in others. Nicely articulates a lot of thoughts that float around in my head, and page 39 might be my favorite - evolution of human ideals based on our current stage of understanding the world.
[an aside: If you study human perception and decision-making long enough you know it's natural human instinct to say "right now is a special time - a fork in the road unlike any other!" So I tend to take issue with those kinds of descriptions. I suppose I'd say this: the above is a good case for why the way we think about the course of humanity is important now - and it is important; though the next era will be faced with entirely new and equally important challenges, just as all the preceding challenges have been critically important as well. in short: I'm not much for doomsday scenarios]
