This document summarizes an article and its corresponding Hacker News discussion about "slow projects"—endeavors that are intentionally or necessarily undertaken over very long timescales, such as decades or centuries. The original article lists examples like the construction of cathedrals, long-term scientific studies (e.g., the LIGO detector, the Framingham Heart Study), and enduring open-source systems.
The subsequent discussion expands on this theme, dominated by a popular (and ultimately debunked) urban legend about Oxford University pre-emptively planting oak trees to replace structural beams centuries later. The debate around this story highlights a core tension: the inspirational power of such parables versus the importance of factual accuracy. Commenters contribute numerous other examples of slow projects, including the multi-generational scientific effort of the cosmic distance ladder and Donald Knuth's decades-long work on The Art of Computer Programming. A crucial point of discussion is the distinction between projects that are necessarily slow (like longitudinal studies) and those that are needlessly slow due to political incompetence and bureaucracy, such as New York's 2nd Avenue Subway. The conversation reflects a deep appreciation for long-term vision and institutional memory, contrasted with a critique of modern society's perceived short-term focus.
A Discussion on the Value and Nature of Long-Term Human Endeavors
Core Premise: The "Slow" Project List: The article presents a list of projects that took exceptionally long to complete, as a deliberate counterpoint to the modern emphasis on speed. Examples include the proof of Fermat's Last Theorem, the construction of cathedrals like the Sagrada Familia, and enduring scientific experiments like the pitch drop experiment.
The Parable of the Oxford Beams: A highly-upvoted comment shares a story about Oxford needing to replace a massive oak beam, only to discover that their predecessors had planted trees centuries earlier specifically for this purpose. The story serves as a powerful metaphor for long-term, multi-generational planning.
A Famous Story Debunked: A reply quickly reveals the Oxford beam story to be an urban legend. The college archivist confirmed that while the replacement wood came from a college-owned forest, it was part of standard, long-term woodland management, not a specific plan for that one building.
The "Spirit" vs. "Facts" Debate: The debunking sparked a meta-discussion. Some argued that the story's inspirational message about foresight is valuable even if fictional, while others emphasized the importance of factual accuracy and cautioned against romanticizing the past.
Necessary vs. Needless Slowness: A key distinction was made between different types of slow projects. Some, like longitudinal studies (Framingham Heart Study) or physical processes (pitch drop experiment), are slow by nature. Others, like the 2nd Avenue Subway, were heavily criticized as examples of needless delay caused by political incompetence, bureaucracy, and mismanagement, not laudable patience.
Additional Examples from the Community: Commenters contributed many more examples of long-term projects:
The Cosmic Distance Ladder: A cumulative, multi-century scientific effort to measure distances in the universe, where each generation built upon the discoveries of the last.
The Art of Computer Programming (TAOCP): Donald Knuth's magnum opus, a project he has been working on since 1962.
The Voyager Probes: Launched in 1977, the probes are still operating decades later, representing an enduring mission of exploration that has outlasted many of its creators' careers.
The Collatz Conjecture & Unsolved Problems: Mathematical problems that persist for generations, representing a continuous, multi-generational intellectual pursuit.
Critique of Modern Short-Termism: The discussion repeatedly touches on a perceived decline in long-term thinking in modern society. Some comments pointedly criticize the "baby boomer" generation for prioritizing immediate rewards over the well-being of future generations.
The Role of Long-Lived Institutions: The thread implicitly and explicitly highlights the necessity of stable institutions—like universities, scientific bodies, and open-source foundations—to shepherd projects that span human lifetimes.
