I picked this book up because I was interested in reading good examples of essays explaining technology to a non-technical audience, an essential skill for good Product Managers. This book had many great analogies, covered significant ground (everything from tech business strategy to how the internet works to hardware and machine learning), and had one of the most interesting, but not the most complete, explanations of software (algorithms + APIs + A/B testing) I've read. Yet while my initial expectation was mostly met, I ultimately felt this book was lacking and would hesitate to recommend it to people interested in product management or anyone who is even moderately familiar with popular tech media (TechCrunch, Business Insider, etc.).
While the topic selection was excellent, many of the explanatory essays were insufficiently ambitious or creative and instead merely summarized popular media coverage. The writing team avoided hard explanations (a more in depth explanation of even one of the algorithms hinted at would have been greatly appreciated), substantive sources (with a few exceptions, including one section on acquisitions where they cite some SEC filings), and gave short shrift to the points of view they did not hold in contentious debates (like in their coverage of net neutrality where they don't really explain or rebut the FCC's decision to classify ISPs as "information services").
This was most painfully apparent in the section entitled "How does Pokemon Go work?". The answer the authors give is essentially camera/sensors + algorithms, the sources cited are mostly written by journalists from publications like Fast Company or by members of fan forums, and the reader ultimately emerges without any additional understanding, regardless of their background (unless they've never heard of Pokemon Go). This is compounded by the continuous anonymous and unqualified references to sources as "experts", "economists", etc. which makes it very difficult to understand who the prominent voices are in each area.
I really like the concept of this book and admire the authors for undertaking this ambitious and broad project. They succeeded in being readable, representing some information using clever metaphors, and highlighting the most important topics in the tech industry. I think a revised version of this book with a pared down topic list, more substantive sources (possibly including interviews conducted by the authors, academic literature from economics, computer science, sociology, etc., legal documents, and the like), and more critical analysis of these sources to give readers a good understanding of the debates going on in technology instead of an almost meaningless taste would be a book I would recommend to anyone interested in learning more about the tech industry.
