This is a superb exposition of how technology changes our world over the longer term in a series of cycles lasting roughly 60 - 80 years. The theories are all explained in simple and easy to understand language, and appended with clear examples.
The current cycle that we are experiencing started in 1971, so depending on when you were born you might find this to be a revelatory text, explaining much of what has happened over the course of your life. In my case for example, as a 40 something, that's my entire life encapsulated as the 1st half of one cycle. Moreover, we are now at the most challenging and important part of the cycle when the fundamental underlying realities of our society need to be radically overhauled, primarily through intelligent governance. If you want to understand how the various power groups of the world are intersecting across the capitalist playing field, right now, this book is essential reading.
