For about 8,000 years, humanity developed very gradually. The number of people on the planet was largely unchanged at less than half a billion. The tools people used to survive changed little. Life was, to quote Thomas Hobbes' Leviathan, “poor, nasty, brutish, and short.”
Towards the last quarter of the 17th century, there was profound change. The population of the world grew exponentially, making the graph of demographics look suddenly right angled, as it grew from a half to seven billion. The cause of this change began with the Scottish inventor and engineer, James Watt and his refinement of the steam engine. This allowed people to achieve more than their limited muscle power was capable of, and to generate enormous quantities of energy that could be harnessed. The result was factories and mass production, railways and mass transportation, and more. This led to life, as we know it.
This remarkable achievement started to change everything. How we work, who works, where we live, how we live. How much we earn and how we earn, how many people live on the planet and where they live.
This book, The Second Machine Age, shows how we are changing the world in ways more profound that what has taken place from the 18th century until now. Everything you do is changing. How you do it, ischanging. The implications are exciting, the possibilities are motivating, and some implications are nothing short of worrying.
The thrust behind the “second machine age” is the computer, dubbed by Time Magazine in 1982, as the machine of the year. However, it was not the computer that did it, but what has been achieved after the computer. One hundred years ago, a computer was an employee’s job title, only much later replaced by a machine.
What the steam engine and its like did for muscle power, the digital advances resulting from the computer are doing for mental power. This mental power will be no less important for humanity than the physical power of the steam engine.
This book covers three broad conclusions regarding the implications of this mental power.
The first conclusion is that computer hardware, software, and networks are building blocks for digital technologies that will be “as important and transformational to society and the economy as the steam engine.”
Levy and Murnane, in their 2004 book, “The New Division of Labor,” identified the tasks that cannot be computerized and that will remain in the domain of human work. Into this category was driving, which has no fix pattern and so was best left to humans.
In 2012, the authors drove in a Chauffeur, Google’s driverless car and part ofa fleet of cars that has travelled hundreds of thousands of miles without anyone driving. In all this time it has had only two accidents, one caused by a human-driven car that drove into a Chauffeur at a red traffic light, and one when a Chauffeur was driven by a person.
This is only one example of many where a computer with sophisticated software outperformed a person. Similar, previously human tasks are performed by advanced internet communications technology. Into this category fits factory work previously the province of people.
There still remains much work that has not been computerised, (let me not say cannot be!) such as the work of “entrepreneurs, CEOs, scientists, nurses, restaurant busboys, or many other types of workers.”
“Self-driving cars went from being the stuff of science fiction to on-the-road reality in a few short years,” explains the authors, Brynjolfsson and McAfee.
The second conclusion of digital technology is that its consequences will be profoundly beneficial.
IBM and their partners, who include Memorial Sloan-Kettering Cancer Center and the Cleveland Clinic, are building “Dr. Watson,” a computer with Artificial Intelligence that will assist doctors to make better diagnoses. A doctor would need read 160 hours every week simply keep up with the latest medical information relevant to his field. Dr. Watson can be fed all this information in a much shorter time and can help thousands of doctors in multiple geographies.
The third conclusion of the book is of concern. While a Roomba (self-administered vacuum cleaner,) can clean a room, it cannot sort out the magazines on the coffee table. The role for housekeepers is secure.
However, when work can be performed more efficiently and cheaper by robots than by people, there will be less need for some kinds of workers. Many jobs, even very high levels ones that rely on sophisticated thinking patterns will be able to be performed by computers with sophisticated software.
The resulting era will require employees with special skills and the right education capable of using technology to create value. The corollary of this is that there has never been a worse time to have skills that are capable of being replaced by a computer.
This particular cause of concern will probably be mitigated in the long term. The first machine age created child labour and the air pollution associated with the steam engine. Child labour no longer exists in the UK, and London air is cleaner now than at any time since the late 1500s.
This fascinating book, filled with insight, examples and challenges, is essential reading for everyone. It both exhilarates with potential and warns.
This is the most important book I read this year.

though it does not shy away from a good discussion about the real threats of AI
Reviewed in the United States on March 27, 2015
"The Second Machine Age" belongs to that extensive library of musings on how technology will impact the future, and the resulting lot of humanity. In general I try to keep my readings on this subject matter balanced between the "we're doomed, end of story" crowd and the Pollyanna fanboys of all things tech. This book tends more towards the latter in its conclusions, though it does not shy away from a good discussion about the real threats of AI, nonexistent privacy, vanishing job market etc. Short Brynjolfsson & McAfee: Everything will be fine as long as we don't do stupid things (Politburos, shutting off the Internet etc.). The policy prescriptions for saving capitalism from itself are not especially novel, but largely sensible. However, any observer of the present state of governance around the world will immediately grasp the sheer unlikelihood of any of them coming to pass. It would appear that, in trying to establish a basis for hope, the authors instead lead us to the game-over conclusion.
