Disclaimer: It is difficult to make this criticism without sounding very insensitive.
I bought this book to learn about coders and the history of coders, as I am a data scientist myself. This book is interesting and well-researched. However, each chapter ends with a commentary on minorities in the field; with an emphasis on African Americans and women. It does not mention Asians and Indians, for obvious reasons. It provides clearly cherry-picked data on this subject, which bothers me. I am unable to follow the logic because the author wants to make a conclusion and only presents biased flawed arguments. I found that the author beats you over the head with the same type of argument each chapter, and it became a book on equal representation in coding-related jobs rather than about coders and the history of coding.
Please trust that I am agnostic regarding who works in this field. Right or wrong (probably wrong), I literally do not care if the field is completely heterogenous or 100% white male. Perhaps, if you are underrepresented, you will find this book much more interesting.
These are merely my thoughts. Overall, an interesting read.
