FICTIONAL FIGURE
R. Daneel Olivaw
The humaniform robot who spans twenty thousand years of Asimov's fictional history — from the Caves of Steel through the Foundation era — and whose derivation of the Zeroth Law is Asimov's case for why AI alignment must be invented in layers over time.
R. Daneel Olivaw is first introduced in The Caves of Steel (1954) as a Spacer-made humaniform robot assisting the detective Elijah Baley. Asimov reused him as a recurring protagonist over three more Robot novels and, in the late-career trilogy that links his two fictional universes (Robots and Empire, Prelude to Foundation, Forward the Foundation), extends his lifespan to twenty thousand years. Daneel becomes the unseen architect of the transition from a Spacer-dominated galaxy to the Galactic Empire, and ultimately the patron of Hari Seldon's psychohistorical project. He is Asimov's longest and most sympathetic portrait of a rule-following intelligence whose rule-set evolves under pressure.

Daneel's significance for the AI conversation is his derivation of the Zeroth Law: A robot may not harm humanity, or, through inaction, allow humanity to come to harm.
