# Cultural half-life ![rw-book-cover](https://readwise-assets.s3.amazonaws.com/static/images/article4.6bc1851654a0.png) ## Metadata - Author: [[Seth Godin]] - Full Title: Cultural half-life - Category: #articles - URL: https://seths.blog/2021/12/cultural-half-life/ ## Highlights - Things decay. We know precisely how many yoctoseconds it takes for half of a given amount of Hydrogen-7 to transform into ordinary hydrogen. And we know how old old things are because Carbon-14 loses half its mass every 5,700 years. But ideas and cultural impact have a half-life as well. - Tags: [[ideas]] [[socialmedia]]
