# The Lindy Effect ## Overview The Lindy Effect, named after a New York deli where comedians discussed career longevity, states that for non-perishable things (ideas, technologies, books, practices), future life expectancy is proportional to current age. If a technology has survived 20 years, it's likely to survive another 20. If it's survived 2 years, expect another 2. **Core Principle:** Time is the ultimate test. Old things that still exist have proven their value; new things are still being tested. ## When to Use - Technology selection (languages, frameworks, databases) - Evaluating libraries and dependencies - Predicting tool longevity - Career skill investment - Methodology and practice adoption - Architectural patterns - Vendor/product selection Decision flow: ``` Choosing between options? → Are some options significantly older? → yes → APPLY LINDY HEURISTIC → Is longevity important for this choice? → yes → FAVOR OLDER, PROVEN OPTIONS → Is the new thing solving a new problem? → yes → NEW MIGHT BE APPROPRIATE ``` ## Understanding Lindy ### What Lindy Applies To (Non-Perishable) - **Technologies:** Languages, databases, protocols - **Ideas:** Mathematical concepts, design patterns, algorithms - **Practices:** Testing, version control, code review - **Books:** Technical references, foundational texts - **Institutions:** Standards bodies, open source foundations ### What Lindy Doesn't Apply To (Perishable) - **Hardware:** Physical degradation limits life
