Nexus is a book about information systems and how it relates to society and specifically nations and their political structures. The book is not what I would call uplifting per se, but more informative and with a slight amount of hopefulness. Besides the AI hype machine happening, it was a useful book for understanding the political trends in the current age. An age of hubris and nationalism.
The first big idea from this book was around political structures and how they relate to information flow. It was a useful framework to understand democracy, authoritarianism, and totalitarianism in relationship to information and control. This was something I had not put too much thought into since school. The book offers a nice refresh on how these systems are different and how they practically affect the lives of those governed with the shift in technology over the past one hundred years.
The second big idea from the book was how AI, with its capabilities, radically changes the game with how information systems can work across various methods of government. The author even-handedly reminds us this works both ways, for the good of good of those in charge and for the bad. They become subjected to the same issues which is outside of their control.
I would tend to recommend this book more for those who have an interest in politics and want to learn about AI.
