This book is important, hilarious, scary, compelling, carefully researched and extremely well-written. Most of my favorite moments are during the interviews in which the author confronts people developing these technologies who have clearly not thought about the ethical implications of their inventions. People who have been surrounded by yes-men for so long, they don’t understand the damage they might inflict if they are not more careful and more conscientious about their process and their product. In response to the reviewer here who complains about the SJW, “social justice warrior,” tone of the book: she may well be a social justice warrior, and more power to her if that’s the case. But this book is not a social justice warrior treatise. It is an amazing piece of investigative journalism (let’s call it IJ for short so people who like to abbreviate things can follow along). She does’t just listen to the people peddling these technologies and reinforce their egos by saying “Wow, that’s really great and cool.” She asks very tough questions, including especially questions of ethics and sociological impact. If you like listening to books I HIGHLY recommend the audiobook version. It’s brilliant.
