Replicator

A replicator is a system or device that can produce copies of itself automatically. Imagine a machine that can make more of itself without human help—this is what a replicator does. In biology, DNA acts as a natural replicator by copying genetic information for reproduction. In technology, some advanced 3D printers or self-replicating robots can create identical copies of themselves, enabling rapid expansion. The concept emphasizes self-duplication for efficiency, scalability, or resource sharing, playing a key role in areas like biology, manufacturing, and theoretical models of self-replicating systems.
