Not exactly “brief” at 17+ hours, I felt like I was taking a college class on AI and the history of communications. YNH shares ideas about how humans network, how information travels and how terrifying our online world currently is and where we go from here. If you have an interest in AI and its future, internet bots, how our online information is taken and used, this book gives you a lot to think about. I enjoyed the ideas I leaned about.
