I agree that it doesn't dive deep into a lot. It also makes notes of things you don't need to know while you're working through the book. That said, if you just want a basic grasp of what is happening to your code when you run it, this is a good place for that. I don't plan on writing a compiler outside of this book, and I don't think this book directly serves doing that. What it does serve is my curiosity in a compact way.
