The Paradox of Fragility
Paper can last 500 years by accident; a hard drive cannot last 10 years on purpose. Digital Longevity is counter-intuitive because it requires movement to achieve stasis. To keep a file "the same," you must constantly migrate it to new storage media and new file formats.
Three Tiers of Longevity
- Technical Longevity: The bits are preserved. (The file opens).
- Semantic Longevity: The meaning is preserved. (We know what the file is).
- Cultural Longevity: The context is preserved. (We understand why it matters).
Field Notes
The "100-Year Archive" Problem: Most tech companies plan for 18 months (the next release cycle). Archaeobytology asks: "What is the stack that survives 100 years?" The answer is rarely the cloud; it is often text files, open standards, and decentralized redundancy.
Longevity vs. Immortality: We do not seek to keep data forever (Immortality), which is impossible and undesirable (Digital Plastic). We seek Longevity—a natural lifespan that matches the cultural relevance of the artifact.
