César Hidalgo on The Infinite Alphabet and the Laws of Knowledge
Knowledge is Not Information
Knowledge is not a commodity that can be copied, pasted, or downloaded; it is a collective, embodied phenomenon that exists only when it is situated within people, teams, and organizations. While information (factual knowledge) is easy to transmit, procedural and conceptual knowledge requires physical embodiment and social networks to function. As César Hidalgo explains, you cannot simply throw engineering manuals and cement into a gorge and expect a bridge to appear, because the manuals contain records of ideas, but the teams possess the actual knowledge.
The Three Laws of Knowledge
Knowledge behaves according to predictable, law‑like principles similar to physics, specifically regarding how it grows, spreads, and is valued.
1. The Law of Time (Growth and Decay)
Knowledge growth typically follows a power‑law learning curve: progress is rapid at the beginning and plateaus over time. This is observed in individual skills (like typing) and industrial costs (like aircraft manufacturing). However, this growth is fragile.
- Knowledge Decay: Knowledge decays rapidly if it is not actively exercised. Hidalgo cites the example of the liberty ships from WWII, where knowledge was estimated to decay by 3% to 6% per month.
- The Polaroid Example: When a vintage film enthusiast attempted to restart a Polaroid plant in the Netherlands, they hired the "A‑team" of former experts. Despite having the original equipment and the best people, the resulting film was initially poor quality and took years to recover. This demonstrates that knowledge disappears when the "muscle" of the activity is not kept fit.
2. The Law of Space (Diffusion)
Knowledge does not diffuse uniformly; it is constrained by geography, social networks, and the "geometry" of the knowledge itself.
- The Principle of Relatedness: Knowledge moves more easily between related activities. Hidalgo uses the example of the Vespa scooter, which was created by an aircraft engineer (Corradino D'Ascanio). After WWII, when Italy was forbidden from making aircraft, engineers jumped to the most "related" available activity: light vehicle manufacturing. This pattern was mirrored in Japan and Germany, proving that innovation often follows a map of existing capabilities.
- The Role of Migration: High‑skill migrants act as vectors for "unrelated" jumps in the product space, bringing new "letters" to an economy's alphabet that locals—who are better at incremental, related innovation—might not possess.
3. The Law of Value (Complexity)
The value of an economy is not determined by its wealth or the amount of information it possesses, but by its "economic complexity"—the diversity of non‑fungible capabilities it can coordinate.
- The Infinite Alphabet: Every unique capability is like a letter in an infinite alphabet. A country's potential for growth is predicted by how many of these "letters" it possesses and how they can be recombined.
- Predicting Growth: By analyzing export data to estimate a country's complexity, Hidalgo can predict future growth. Countries with higher complexity than their current income suggests (e.g., India) are more likely to experience rapid growth than those whose income is high but complexity is low (e.g., Qatar).
Architectural Innovation and the Incumbent's Dilemma
Innovation is divided into gradual (component) changes and architectural changes. Gradual innovation involves replacing a part (e.g., a more powerful engine in a propeller plane) without changing the system. Architectural innovation requires redesigning the entire system (e.g., moving from propeller planes to jet engines).
This explains why established firms often fail. Barnes & Noble had the same "knowledge" about books as Amazon, but their organizational architecture was designed for wholesale and retail, not for direct‑to‑consumer logistics. The shift to shipping individual books was not a small incremental change but an architectural one that required a completely different organizational design.
Knowledge, Institutions, and LLMs
Institutions vs. Knowledge
Economic development is often mistakenly viewed as a matter of providing financial capital or implementing institutional reforms. However, Hidalgo argues that the demand for institutions often comes from knowledge‑intense workers. In China, the push for entrepreneurial freedom was led by high‑level physicists and researchers who saw the "professor‑entrepreneur" model in the US and demanded the institutional space to implement it in China.
Do LLMs Have Knowledge?
From Hidalgo's perspective, knowledge is a collective phenomenon. Therefore, the question is not whether a Large Language Model (LLM) "has" knowledge in an individual sense, but whether it increases the collective intelligence of the human ecosystem. LLMs act as a cultural technology—similar to books—that helps humans retrieve and recombine information more efficiently, thereby accelerating individual and collective learning.
요약
César Hidalgo는 지식이 비대체적이며 집합적인 현상으로, 성장, 확산, 소멸이라는 물리학과 유사한 법칙을 따른다고 주장한다. 따라서 지식은 체험과 구현 없이 단순히 다운로드하거나 복제할 수 없다.
