The Fourth Age

We could say that the distinguishing characteristic of the last century is the enormous number of changes that have taken place, dozens if not hundreds of technological progresses that have revolutionised our lives.  Having said that, in the general span of human history, little has changed over the past five thousand years; we still have mothers, fathers, children, schools, governments, war and peace, in the same way that our ancestors did five millennia ago.  The extraordinary thing of our time is not the change that we have already witnessed, it is the change that is still to come.  There have only been three major technology-driven changes in the entire human history, changes to groups of inter-related technologies that have deeply transformed us, both permanently and biologically; this book is about the fourth.
