This article discusses the concept of copying complex objects or behaviors and how creators can recognize when their work has been copied. The author explains that when you copy something, you unknowingly include random features that the creator knows are there but you do not. These additional random features become a way for creators to identify when their work has been copied. The concept seems to apply only to objects or behaviors that are complex enough to contain this additional randomness without losing its structure or meaning.
