This document summarizes a blog post titled "Slow" and its accompanying Hacker News discussion, both of which explore the concept of long-term, goal-oriented human projects that span decades or centuries. The original article provides examples such as the construction of cathedrals (Notre Dame, Sagrada Familia), multi-generational scientific endeavors (Framingham Heart Study, LIGO), and complex mathematical proofs (Fermat's Last Theorem). The Hacker News discussion significantly enriches this by introducing further examples, critical perspectives, and philosophical debates. A central topic is the parable of the Oxford college planting oak trees for future replacements, which is used to discuss institutional foresight and stewardship, despite the story being an urban legend. Commenters also contribute powerful examples like the "cosmic distance ladder" and critique projects like the 2nd Ave Subway as symbols of inefficiency rather than necessary slowness. The discussion explores the nature of these projects, differentiating between those inherently requiring time and those delayed by incompetence or circumstance, and touches on the societal and political structures that enable or hinder long-term thinking.
Slow Projects: An Exploration of Multi-Generational Human Endeavors
The Core Premise: The article identifies and celebrates "slow projects"βgoal-directed human endeavors that take decades, centuries, or even millennia to complete, serving as a contrast to projects praised for their speed and immediate results.
Key Examples from the Article: The author lists several types of slow projects, including:
Construction: Massive architectural works like the Sagrada Familia (begun 1882 and ongoing) and historic cathedrals like Notre Dame (1163-1345) that spanned multiple generations.
Scientific Studies: Longitudinal research designed to observe slow processes, such as the Framingham Heart Study (since 1948), the Cape Grim Air Archive (since 1978), and the E. coli long-term evolution experiment (since 1988).
Mathematics: The proof of Fermat's Last Theorem is presented as a quintessential slow project, relying on centuries of cumulative mathematical development to solve a single, well-defined problem.
The Oxford Beam Parable: A major thread in the discussion revolves around the famous story of an Oxford college that purportedly planted oak trees centuries in advance to replace the main hall's beams. While the story is debunked as an urban legend, commenters noted that the college did maintain forests for long-term timber needs, and the story serves as a powerful parable for institutional foresight and planning for future generations.
A Critique of "Slow": Inefficiency vs. Necessity: A crucial counterpoint raised in the discussion is that not all long projects are noble. The 2nd Ave Subway in Manhattan, while taking decades, is highlighted as an example of political incompetence, bureaucratic failure, and exorbitant cost, not a project that inherently required a long time.
The Cosmic Distance Ladder: A commenter provided a detailed example of a "good" slow project: the cosmic distance ladder. This is a multi-generational scientific endeavor where each new understanding (the Earth's radius, the distance to the Moon, the distance to the Sun, etc.) builds directly upon previous discoveries, showing a continuous, focused accumulation of knowledge over centuries.
Preserving Generational Knowledge: The discussion touched on the importance of actively preserving knowledge and skills over time. An example given was of Japanese temples that are torn down and rebuilt from scratch every few decades, ensuring that the craft and expertise are passed to the next generation of builders.
Individual and Creative Slow Projects: Commenters expanded the list to include individual creative works that take a lifetime, most notably Donald Knuth's "The Art of Computer Programming," which has been in progress since 1962.
Tension with Modern Incentives: A recurring theme is the conflict between the long-term vision required for these projects and modern society's short-term incentives, such as four-year election cycles in democracies or quarterly profit reports in business, which can discourage planning for a future one will not see.
