The Evolution of Prosperity: Understanding Technological Progress

Recent discussions surrounding the Economics Nobel prize, particularly the work of historian Joel Mokyr, have shed light on the fundamental mechanisms that drive human progress. By examining the European Enlightenment and the history of innovation, we can better understand why technology—and the economic growth it brings—is not an inevitable constant, but a fragile achievement.

Bridging the Gap: Prescriptive vs. Propositional Knowledge

In the Middle Ages, Europe saw various inventions like mechanical clocks and deep plows. However, these did not lead to widespread wealth. Mokyr suggests this was because knowledge was siloed into two distinct categories:

• Prescriptive Knowledge: This refers to "instructions and mechanics"—the practical, trial-and-error techniques passed down to craftsmen, such as masons building cathedrals without understanding the underlying physics.
• Propositional Knowledge: This encompasses the "laws of nature," mathematics, and theoretical physics.

For centuries, these two worlds remained separate. The turning point occurred around the 1600s with figures like Francis Bacon, who advocated for scientific inquiry and precision. By encouraging scientists to test theories through experimentation, the Enlightenment created a "feedback loop" between theory and practice. This marriage allowed for the refinement of technologies, such as applying the understanding of atmospheric pressure to improve steam engines, thereby transitioning from mere craft to sustained technological advancement.

The Role of Institutional Openness

Innovation requires more than just scientific discovery; it requires an environment that permits change. Mokyr emphasizes that "a country's openness to change is a key ingredient for sustained economic growth."

Historically, those in power often view new technologies as threats to their existing interests. The evolution of the British Parliament in the 1800s provided a platform for a broader array of stakeholders to advocate for advancements like railroads, even when they were disruptive. However, Mokyr cautions that institutions do not necessarily improve over time. Citing his colleague Douglas North, he notes that institutional quality is cyclical and can degrade, as seen in the interwar period of the 20th century, suggesting that the current global climate may be facing similar volatility.

The Costs of Progress and the Future of AI

Technological advancement inevitably produces "bankruptcies, layoffs, and dislocation." Modern debates, such as the Hollywood writers' strike regarding AI, mirror historical anxieties where vested interests resist automation. Yet, Mokyr remains optimistic about the long-term trajectory, arguing that machines do not simply replace humans; they push the workforce toward "more interesting, more challenging work."

Despite this, Mokyr describes technological progress as a "fragile and vulnerable plant." It is easily arrested by external shocks and requires constant cultivation. He reminds us that technology is a neutral tool—like a hammer that can build a home or cause harm—and its outcome depends on human intent.

Conclusion: Inventing Our Way Out

As we face existential threats like "climate change and demographic change," Mokyr argues that we cannot afford to stagnate. Because these crises are unprecedented, the only viable path forward is to "invent ourselves out of it." Sustained economic growth is not a guaranteed historical trend, but a precious outcome that requires continued investment, incentives, and a commitment to scientific inquiry.
