Past future On the last topic alone, I found several insightful thoughts surrounding the complexity of our current technology systems and infrastructure, and how that may impact our future. For example, on page 275: “In the past two decades, this complexity has expanded in all segments, including our homes — the household Internet structure has routers, Wi-Fi, access points and modems. … We are victims of the complexity that is needed to make the use of these technologies as simple as possible.” While many books have been and will be written on these diverse topics, Perelmuter has offered amazing summaries in an easy-to-read format that is not too long (total of 281 pages before acknowledgments, index and bibliography).
