My biggest criticism (& thus the non-recommendation for the book) is that the technologies for making these monitoring of human behavior that Pentland describes are dehumanizing and a grave insult to personal privacy. The authors vague promises of a personal data store that would broker our most personal information are unrealistic. If these plans pan out, we will always be watched over by machines that seek only to predict our patterns of behavior and exploit them. An algorithmic prison awaits us.
Every once in a while the author describes unexpected behavior by individuals thus modeled, and betrays an element of surprise that we might step out of our everyday paths into something his system doesn't contain. It's a glimmer of hope in a dystopian world that we might surprise our ever-present overseers and do something that their social physics does not anticipate.
The first chapter sets out the conditions of the visit and explains that he was given comfortable accommodations, a meal allowance, and the run of the airport in exchange for his writing. As such it's a comfortable account of the place where nothing really goes wrong for him, and not the interminable journey that most people would experience if they were cooped up waiting in long lines for ever-delayed flights.
