There are some good ideas in this book, and a large variety of interesting references and historical anecdotes, but ultimately he is repeating himself over and over, and lacks the philosophical heft to properly reach his best conclusions. He should have applied Occam's Razor, in the same way he might have done as an engineer.May be a more interesting read for a non-engineer, or a passable speed-read skim, or for a reader more enamored with the expansive post-modern style of the "non-fiction adventure" that covers every recycled angle of the same concept.
