If we had a theory of intelligence that allowed us to say "this is why and how machines are intelligent and how they become more intelligent" we'd likely be very close to solving the alignment problem as well, obviating the need for the book.

The book fits into the current unknown-unknowns world of rapidly increasing machine-learning capabilities across most domains where there is little evidence to suggest that "intelligence" is limited to the human limit (which is already quite high relative to the 99.9th percentile; we get a few Einstein, Von Neumann, Turing class people in a century) or the human body.
