The relentless march of technological progress has consistently reshaped human civilization, bringing forth periods of profound transformation that have touched every facet of our existence.1 From the mastery of fire and the invention of the wheel in antiquity to the dawn of the digital age, each technological revolution has been met with a mixture of excitement and apprehension. Today, we stand at the cusp of another such epochal shift, driven by the rapid advancements in Artificial Intelligence (AI). As AI continues to permeate our lives, anxieties surrounding its potential impact on employment and the very fabric of society have understandably risen. Will AI lead to mass job displacement? Will it exacerbate existing inequalities? Or will it, like its predecessors, ultimately usher in a new era of prosperity and opportunity for humanity?
To navigate these uncertainties, it is invaluable to look to the past. This article delves into the economic history of seven pivotal technological revolutions that have unfolded over the centuries: the printing press, the steam engine, the telegraph, the automobile, mass production, the internet, and the personal computer. By examining each of these transformative periods through a detailed economic lens, we aim to illuminate the mechanisms through which technological innovation has historically generated net positive outcomes for humanity and its effect on the job market. Our analysis will explore how each revolution impacted productivity, the cost and availability of goods, disposable income, the nature of work, and the broader economic principles at play. Furthermore, we will connect these historical examples to the insights of economist Henry Hazlitt, who eloquently argued for the long-term benefits of technological progress. By understanding these historical patterns, we can then draw analytical conclusions about the potential long-term economic impact of the AI revolution, addressing the critical question of whether AI is likely to result in a net loss of jobs.
The Gutenberg Revolution out of Germany
The world before the printing press was a realm where knowledge was a precious and scarce commodity.3 Books, the vessels of information and ideas, were painstakingly produced by hand, often by scribes laboring in the quietude of monasteries.3 This manual process was not only arduous and time-consuming but also incredibly expensive, rendering books a luxury accessible primarily to the elite – the clergy, the nobility, and the wealthy.3 Consequently, literacy rates across Europe remained low.10 The limited availability of information constrained the complexity of tasks that individuals could manage.
In the mid-15th century, a German goldsmith named Johannes Gutenberg, working in Mainz, revolutionized information dissemination with his invention of the movable type printing press.52 This innovation ingeniously combined existing technologies – the screw press, paper manufacturing, and ink development – in a novel way.54 Initially, the advent of the printing press was met with resistance and concerns about potential job losses for scribes.10
The economic impact of the printing press was profound. Firstly, it drastically increased productivity by mechanizing the reproduction of texts. A single printing press could produce up to 3,600 pages per workday, a stark contrast to the mere forty pages achievable through manual hand-printing.52 This exponential increase in production led to a significant reduction in the cost of books, making them more widely available to a larger population.55 The price of books fell steadily for over a century after Gutenberg’s invention.55 This newfound affordability increased disposable income for various segments of society, allowing them to allocate their purchasing power to acquiring knowledge and leisure reading.52 Furthermore, the printing press changed the nature and complexity of tasks that could be performed. The standardization and wider dissemination of knowledge spurred intellectual growth, contributing to the Renaissance, the Reformation, and the Scientific Revolution.4 The broader economic principles at play included shifts in supply and demand for books and literacy, the allocation of resources towards paper and ink production, the formation of capital in printing businesses, and the reinvestment of profits into expanding printing operations and related trades.52 This ultimately led to the creation of new markets for printed materials and services. This aligns with Henry Hazlitt’s perspective that technological advancements boost overall wealth and create new opportunities.59
The resulting “New World” saw a dramatic increase in literacy rates across Europe, empowering individuals with access to knowledge and fostering a more informed public.4 The printing press facilitated the spread of Renaissance humanism and the ideas of the Protestant Reformation, leading to profound cultural and religious transformations.4 In terms of the job market, while the printing press did lead to the decline of the occupation of scribes, it simultaneously created numerous new jobs for printers, typesetters, bookbinders, illustrators, publishers, and booksellers.10 This shift demonstrates how technological advancements can restructure the labor market, leading to new forms of employment that cater to the evolved needs and capacities of society.
The English Steam Engine
Before the advent of the steam engine, the world relied heavily on human and animal labor, as well as the inconsistent and geographically limited power of wind and water.16 Production was often localized and limited by the availability and reliability of these power sources, resulting in relatively low productivity and high costs for goods.
The innovation that would transform this reality was the steam engine. While rudimentary steam-powered devices existed earlier, it was the work of Thomas Savery and Thomas Newcomen in the late 17th and early 18th centuries that led to the first commercially successful engines, primarily used for pumping water out of mines.8 However, the true revolution came with James Watt’s improvements in the late 18th century, which significantly increased the efficiency and versatility of the steam engine.8 Watt’s engine found widespread applications in factories, powering machinery and enabling mass production, as well as in transportation through the development of steam-powered railways and ships.10
The steam engine revolutionized productivity by providing a reliable, scalable, and location-independent power source, leading to significant increases in production across various industries.16 This surge in production led to a reduction in the cost of goods, making them more affordable and widely available.16 Increased production and lower costs boosted disposable income and purchasing power for many. The advent of steam power also shifted the nature of work from skilled craftsmanship to more specialized tasks in factories, requiring new skills to operate and maintain the machinery 16. The steam engine spurred broader economic growth by enabling industrial expansion, facilitating trade through railways and steamships, and fostering the growth of crucial related industries like coal, iron, steel, and machinery 16. This aligns with Hazlitt’s assertion that technological progress drives overall economic welfare.59
The “New World” shaped by the steam engine was characterized by the rise of industrial cities, increased urbanization, and a significant expansion of global trade networks.16 While some jobs, particularly in traditional crafts and agriculture, were displaced by mechanization, the steam engine created a multitude of new jobs in mining (to fuel the engines), in factories (to operate and maintain the machinery), and in transportation (as railway engineers, firemen, and ship crew).16 The overall impact on the job market was a significant expansion and transformation of the workforce.
The Telegraph out of the USA & UK
Before the telegraph, communication across long distances was a slow and unreliable process, dependent on the physical transportation of messages by messengers on horseback or ships.12 This made real-time coordination and the rapid dissemination of information virtually impossible.
The invention of the electric telegraph in the mid-19th century by Samuel Morse in America and independently by others in Europe, marked a paradigm shift in communication.45 This technology allowed for the near-instantaneous transmission of coded messages over wires, revolutionizing the speed and efficiency of long-distance communication.12
The telegraph dramatically increased productivity in various sectors. Businesses could now coordinate operations across vast distances in real-time, leading to more efficient supply chains and market integration.12 The cost of communication plummeted compared to traditional methods, making it more accessible for businesses and individuals to exchange information.11 This improved efficiency and reduced costs contributed to increased disposable income and purchasing power by facilitating trade and commerce. The telegraph also changed the nature of tasks, enabling the rise of new professions such as telegraph operators and technicians, and increasing the complexity of managing geographically dispersed organizations.149 The broader economic principles at play included the creation of a global communication network that fostered trade, facilitated financial transactions, and supported the growth of news dissemination.149 Hazlitt would have viewed this as a clear example of technological progress enhancing economic activity and overall societal benefit.59
The “New World” after the telegraph was characterized by a more interconnected and globalized society. News and information could travel across continents in minutes, shrinking the perceived distance between people and places.149 The telegraph had a profound impact on the job market, leading to the decline of messengers who physically carried information and the creation of numerous jobs in the telegraph industry itself, including operators, technicians, and administrative staff.149 The telegraph also facilitated the growth of related industries such as news agencies and financial markets.149
The Automobile out of Germany
Before the widespread adoption of the automobile in the early 20th century, personal transportation was primarily reliant on horses and horse-drawn carriages, as well as developing railway and streetcar systems, particularly in urban areas.119 Travel was often time-consuming, limited by distance and the endurance of animals, and could be uncomfortable and costly for individuals.
The invention and mass production of the automobile, pioneered by figures like Karl Benz, Gottlieb Daimler, and Henry Ford, revolutionized personal transportation.171 The automobile offered unprecedented mobility, freedom, and convenience, transforming daily life and reshaping urban and rural landscapes.146
The automobile dramatically increased productivity by enabling faster and more efficient personal and goods transportation.177 It reduced the time and cost associated with travel, expanding access to jobs, services, and leisure activities.146 This increased mobility boosted disposable income and purchasing power by facilitating commerce and enabling people to live further from their workplaces, leading to suburbanization.180 The automobile also fundamentally changed the nature of tasks, leading to the decline of horse-related occupations and the rise of a massive automotive industry, including manufacturing, sales, repair, and infrastructure development.190 The broader economic principles involved the creation of a vast network of related industries, including oil and gas, rubber, steel, and road construction, leading to significant capital formation and reinvestment.190 Hazlitt would have highlighted the increased overall wealth and convenience brought about by the automobile, despite the displacement of some older industries.59
The “New World” shaped by the automobile was characterized by suburban sprawl, a car-centric culture, and increased personal freedom and mobility.191 The impact on jobs was transformative, with the decline of horse-related occupations (carriage makers, blacksmiths, stable hands) being more than offset by the creation of millions of jobs in the automotive industry and its supporting sectors.193
Mass Production out of the USA
Prior to the widespread adoption of mass production techniques, goods were often crafted individually or in small workshops by skilled artisans. This resulted in higher costs and limited availability for many consumer products.
The introduction of mass production, spearheaded by innovations like the assembly line, particularly in the automobile industry by Henry Ford, revolutionized manufacturing.211 This system involved breaking down complex tasks into smaller, repetitive steps performed by specialized workers, leading to unprecedented levels of efficiency.
Mass production dramatically increased productivity, allowing for the manufacture of goods at a much faster rate and lower cost per unit.211 This led to a significant decrease in the price of many consumer goods, making them more affordable and accessible to a larger segment of the population.211 Consequently, disposable income and purchasing power increased for many, enabling them to acquire a wider range of goods and services. Mass production changed the nature of work, shifting the focus from highly skilled craftsmanship to specialized, often repetitive tasks on assembly lines.211 This required a large workforce trained in specific, narrow skills. The broader economic principles at play included economies of scale, increased division of labor, standardization of parts, and the creation of vast distribution networks to handle the increased volume of goods.211 Hazlitt would have emphasized how mass production enhanced overall economic output and improved the standard of living for the majority.59
The “New World” shaped by mass production was characterized by a significant increase in the availability of affordable consumer goods, leading to a higher standard of living for many.211 The impact on jobs was complex. While some skilled artisan roles declined, mass production created a huge demand for factory workers, assembly line workers, and managers to oversee the production process.211 It also spurred the growth of industries related to the mass production of raw materials and components.
The Internet out of the USA
Before the internet became widely accessible in the mid-1990s, communication and information sharing relied heavily on traditional methods such as mail, telephones, and physical documents.215 Access to information was often limited to physical libraries and other centralized sources.
The invention and proliferation of the internet, building upon earlier work on computer networking and packet switching (ARPANET) 70, revolutionized communication and access to information on a global scale.70 The development of the World Wide Web by Tim Berners-Lee further enhanced the internet’s usability and accessibility.215
The internet dramatically increased productivity across numerous sectors by enabling instant communication, facilitating collaboration, and providing access to a vast repository of information.222 The cost of communication and information sharing plummeted, fostering globalization and the growth of online commerce.222 This increased efficiency and reduced costs have had a significant impact on disposable income and purchasing power by creating new markets and business models. The internet has fundamentally changed the nature of tasks, leading to the rise of entirely new industries and professions in the digital realm, such as software development, web design, digital marketing, and data analysis.225 The broader economic principles at play include the creation of a global digital marketplace, the rise of e-commerce, the increasing importance of data and information, and the network effects that drive the growth of online platforms.222 Hazlitt would likely view the internet as a powerful engine for economic growth and innovation, despite the disruptions it has caused to traditional industries.59
The “New World” of the internet age is characterized by unprecedented levels of connectivity, access to information, and globalization.222 The impact on jobs has been significant, with the decline of some traditional roles (e.g., travel agents, traditional retail) being accompanied by the creation of a vast array of new jobs in the digital economy.225 The internet has also enabled new ways of working, such as remote work and the gig economy.227
The Personal Computer out of the USA
Before the widespread adoption of personal computers (PCs) in the late 20th century, computing power was largely confined to large, expensive mainframe computers accessible mainly to corporations, governments, and research institutions.58 Individual access to computing was limited, and tasks were often performed in batch mode by specialized personnel.
The invention and mass production of the personal computer, with early models like the Altair, Apple, and IBM PC 58, revolutionized computing by making it accessible to individuals and small businesses.58 The development of user-friendly operating systems and software further expanded the PC’s appeal and utility.58
The personal computer significantly increased productivity by automating tasks, improving efficiency in office work, and enabling new forms of creativity and communication.31 The cost of computing power decreased dramatically, making it affordable for a wide range of users.31 This increased accessibility boosted disposable income and purchasing power by enabling individuals and businesses to perform tasks more efficiently and create new value. The PC fundamentally changed the nature of work, leading to the decline of some manual and clerical jobs while creating new roles requiring computer literacy and specialized software skills.225 The broader economic principles involved the rise of the software industry, the growth of IT services, and the increasing importance of digital skills in the modern economy.225 Hazlitt would have seen the personal computer as a prime example of how technological innovation empowers individuals and drives economic progress.59
The “New World” of the personal computer era is characterized by a digitalized society where computers are integral to work, education, communication, and entertainment.258 The impact on jobs has been transformative, leading to a significant shift in the skills required by the workforce and the creation of a vast number of jobs in the technology sector.225
Synthesis of Historical Technological Revolutions
Examining these seven technological revolutions reveals several common patterns in their economic impact. Firstly, each innovation led to a significant increase in productivity, either by automating existing tasks, enabling new processes, or improving the efficiency of production and communication.52 This surge in productivity invariably resulted in a reduction in the cost of goods and services, making them more accessible to a wider population.55 The increased affordability, in turn, often led to a rise in disposable income and purchasing power for various segments of society.55
Furthermore, each technological shift altered the nature of work. While some jobs were displaced or became obsolete, entirely new industries and occupations emerged to support the new technologies and cater to evolving societal needs.52 This process often involved a shift from manual and artisanal labor towards more specialized and technology-driven roles. The broader economic principles consistently observed include the interplay of supply and demand, the reallocation of resources, the formation of new capital, and the creation of entirely new markets.55 These patterns align with Hazlitt’s core argument that technological progress, despite initial disruptions, ultimately contributes to long-term economic growth and an improved standard of living.59
However, there were also unique differences in how these revolutions unfolded. The printing press primarily impacted the information and knowledge sectors, while the steam engine and mass production revolutionized manufacturing and transportation. The telegraph and internet focused on communication, while the automobile and personal computer transformed personal mobility and individual productivity. The speed of adoption and the scale of impact also varied across these revolutions. The internet and personal computer, for instance, diffused much more rapidly than the steam engine in its early stages.
Conclusions on the AI Revolution
Drawing upon these historical patterns and the economic principles discussed, we can now turn our attention to the potential long-term economic impact of the AI revolution on society and the job market. Like previous technological transformations, AI promises significant increases in productivity across a wide range of industries.266 AI has the potential to automate tasks currently performed by humans, leading to greater efficiency and lower costs for goods and services.266 This could lead to increased disposable income and purchasing power over time.
However, the AI revolution also presents potential challenges. There are valid concerns about the displacement of jobs, particularly in sectors involving routine and automatable tasks.266 The nature of work will undoubtedly change, requiring a workforce that is adaptable and equipped with new skills to work alongside AI systems and in emerging AI-related fields.266
Despite these challenges, historical evidence strongly suggests that the AI revolution is likely to result in a net positive outcome for humanity and the job market in the long run. Previous technological revolutions, while causing temporary disruptions and job shifts, ultimately led to the creation of more jobs and an overall improvement in living standards.226 AI is expected to follow a similar trajectory, automating some tasks and even entire roles, but also creating new jobs in areas such as AI development, data science, AI maintenance, and in entirely new industries that have yet to emerge.226 Take for instance the barrier of entry for new entrepreneurs in any industry, that barrier has been lowered continuously as AI made progress and we now see small teams achieving unicorn ($1bn+) status significantly quicker than ever before, offering new services and products to millions of people. The focus should be on adapting to these changes through education, reskilling initiatives, and fostering a culture of lifelong learning.26
In conclusion, while the transition to an AI-driven economy may present challenges, the historical record offers a compelling narrative of technological progress leading to net positive outcomes. By embracing adaptation, investing in education, and fostering innovation, society can harness the transformative power of AI to create a future with new opportunities and an improved quality of life for all, echoing Henry Hazlitt’s optimistic view of technological advancement.59
