GEB is one of the best works of modern philosophy, I don't think the reviewer gets the point, the story of formal systems and the structures that determine them are used as an analog for other systems that aren't formal to try and shed light on the process of ontological emergence of intelligence. If you are at least a bit interested in philosophy and computation, you should read GEB at least once.
