The title is a reference to The Outer Limits: I, Robot (1964). It had a similar story of a robot believed to have evil intentions but as the story progressed, he was discovered to be very human with many human ideals. The title is also a reference to Isaac Asimov's short story collection I, Robot, which dealt with similar themes of a single unit of a collective consciousness discovering free will and identity.
