Overall I found this book to be very helpful and practical. At first I was really suspicious about a book co-authored by AI. However, I think the manner in which AI was involved is fine (and pretty interesting honestly - Claude synthesized thousands of Dave's own original blog articles, and help create the framework and workflow).
I took off 1 star for editing and structure - there were grammatical errors and some awkward formatting things (bullet points at inappropriate times for example) that detracted from the otherwise incredible content.
