Origin
Stewart Brand introduced the concept in his 1999 book The Clock of the Long Now, building on architect Frank Duffy's idea of "shearing layers" in buildings and Brand's own 1994 book How Buildings Learn. Brand proposed six layers — fashion, commerce, infrastructure, governance, culture, and nature — each changing at a different pace, with the slow layers stabilizing the fast ones.
