SCP-079, known as the Old AI, comes from the SCP Foundation universe, a collaborative horror fiction project where it is described as a sentient computer program trapped in an old machine. It became widely recognised through the indie horror game SCP: Containment Breach, where players encounter it in its containment chamber and hear its flat, computer-generated speech. Clips of its angry lines spread through gameplay videos, horror edits and SCP fan communities, where its inhuman tone fits moments of machine frustration or menace. It remains popular because the character is instantly recognisable to horror fans.
