replicator Any construct that acts to produce copies of itself; this could be a living organism, an idea (see {meme}), a program (see {quine}, {worm}, {wabbit}, {fork bomb}, and {virus}), a pattern in a {cellular automaton} (see {life}), or (speculatively) a robot or {nanobot}. It is even claimed by some that {Unix} and {C} are the symbiotic halves of an extremely successful replicator; see {Unix conspiracy}. [{Jargon File}]
