I also just started a book on Life after Google and am still reading “From Guttenberg to Google.” Both of these books describe the technological developments and the resulting upheaval of major breakthroughs, e.g. railroads, telegraph, and computers. These breakthroughs cause massive loss of jobs and the creation of new ones. Life After Google is more on what’s to come. Many financial analysts are using this to be cautionary about buying or trading high technology stocks.
