The universe is obviously not tuned for space faring intelligent life. What the Anthropic Principle or Self-Sampling Assumption actually says is the universe is tuned to include our form of intelligent life, maybe others too, but not necessarily all forms of intelligent life. I haven't read the book, but basically we could not observe a universe that was not tuned for us, so it should not surprise us to see that it is.
