That may be his intention. But an author is not in full control over how a reader will interpret his work. And there is no doubt that a lot of people will read this work as if it is a tool for teaching their child coding, rather than as a way to teach them about what it is they do all day.

Maybe it's a mix of both. I think it's a huge stretch to say the author or this book is weighing in on nature vs nurture and genetics vs practice debates though.
