Summary of: The Second Machine Age: Work, Progress, and Prosperity in a Time of Brilliant Technologies
By: Erik Brynjolfsson


Brace yourself for a gripping journey through the transformative Second Machine Age, where digital technologies revolutionize the way humanity deals with conceptual labor. This book summary underscores the incredible progress and challenges presented by these advancements, demonstrating how digital technology is reshaping the future of employment, innovations, and our interaction with goods and services. Get ready to explore the profound implications of the rapid exponential growth within the realms of autonomous vehicles, language processing, computing capacities, and mass digitalization as we enter an age of unprecedented possibilities.

The Second Machine Age

The Industrial Revolution changed how people used their bodies for work, and we are now undergoing a comparable revolution that changes how people use their minds for conceptual labor. Digital technologies advanced at an exponential pace and opened doors for innovation. Progress is evident in the consumption industry, but society still faces challenges.

The Evolution of Digital Technologies

The exponential growth of digital technologies has produced remarkable breakthroughs in various fields, including language processing, robotics, and autonomous vehicles. The author highlights how computers have evolved to perform complex tasks that were once thought impossible, leading to extraordinary productivity growth in the American economy. Since the 1960s, Moore’s Law has driven exponential growth in computing capacity, which has resulted in an accelerated pace of technological advancement. Today, we see autonomous cars navigating through bustling highways with ease, a feat unimaginable just a decade ago. In the era of technological transformation, the possibilities for innovation and growth seem limitless.

The Intersection of Innovation and Technology

In today’s world, the rise of inexpensive computing and mass digitalization has led to remarkable changes. The cost of access to information has dropped significantly, and the spread of ideas and cultural trends has become easier than ever before. The availability of digitized older works has made it possible for scholars to gain new insights using innovative tools. However, there is still a debate about whether innovation is rising or falling. While some experts believe that information technology lacks the pervasive power of earlier breakthroughs like steam power and electricity, others argue that digital technologies are accelerating intellectual combinations, hybridizations, and cross-pollinations. In this context, free market endeavors like Quirky and Kaggle are using digital platforms to seek solutions, and government agencies like NASA use online venues to identify better ways of predicting solar flares. What is clear is that the fusion of innovation and technology is transforming our economy and our society.

Adapting to New Technology

The challenges of incorporating new technology into society can hinder productivity growth, and GDP fails to capture its impact.

Incorporating new technology into society can be challenging, as past examples such as the adoption of electricity has shown. When electricity was first introduced, people replaced steam engines with electric motors but did not change the layout of factory designs. This caused inefficiencies as electric motors required a different machine arrangement that revolved around workflow instead of energy needs. This shift took 30 years to implement, but only then did electricity lead to surges in productivity.

Similarly, companies integrate computers minimally at first, but they later undertake efforts to generate surges in productivity. However, gross domestic product (GDP) fails to capture the true impact of digital technologies on society’s overall well-being. GDP’s limitations obscure its understanding of the economy and poorly measure the rise of access to information and entertainment, which is often free to access and, therefore, invisible to GDP. The digital world has additionally accelerated productivity in certain areas, leading to the same products being produced at a much faster pace. Despite this, GDP fails to capture the positive impact on society, raising concerns about income inequality and other measures of spread.
