The 'Lindy' meme stems from the Lindy Effect, a concept popularized by Nassim Nicholas Taleb suggesting that the future life expectancy of non-perishable things is proportional to their current age. In internet subcultures, particularly on Twitter and finance forums, 'Lindy' became a shorthand for anything that is robust, traditional, and likely to endure, while 'Non-Lindy' refers to fragile modern fads. The visual identity of the meme often involves a simplified sketch of a man walking—the 'Lindy Walk'—or comparisons between ancient practices and modern failures. It is used to signal a preference for time-tested wisdom over recent innovations, often with a touch of irony or intellectual superiority.
