I think it's well intentioned and the author seems like someone who has put a lot of work into something they think is important, but it contains some terrible technical misunderstandings, and that's a real shame as I cringe thinking about a developer without a CS degree who's read this book to make themselves more confident in interviews repeating some of the stuff in it.
