# Long Now **Domain:** Long-Term Thinking / Institutional Time **Doc Type:** Canonical Concept-and-Institution Node **Maturity:** Developed ## Definition **Long Now** names an approach to responsibility and design across very long horizons and the San Francisco-based Long Now Foundation established to cultivate long-term thinking. ## Evolutionary Nexus Deep time, redwood longevity, fossils and genome lineages in [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] place current technological choices inside histories far longer than product cycles. ## Continuity Context Continuity infrastructure must survive institutional turnover, format decay and energy transitions. Long-term design therefore includes maintainable interpretation, succession of custody and responsibilities to subjects who may outlive their original providers. ## Sources / Provenance - Long Now Foundation: https://longnow.org/ ## See Also [[wiki/Technical Obsolescence|Technical Obsolescence]], [[wiki/Continuity Stack|Continuity Stack]], [[wiki/El Palo Alto|El Palo Alto]], [[wiki/Intergenerational Governance|Intergenerational Governance]]
