Lex Fridman interviews Eugenia Kuyda (co‑founder of Replika). Kuyda recounts Replika’s origin—built initially from text messages with her late friend Roman (killed in a 2015 hit‑and‑run)—and frames the project as a response to human loneliness. The conversation covers loneliness as a public‑health problem (self‑reported prevalence among young adults, physiological impacts), Replika’s product and measurement strategy (short‑ and long‑term outcome metrics), technical choices (retrieval vs generative models, GPT‑3 integration, memory limitations), and product features (text/voice chat, augmented‑reality avatars, diaries). The interview also includes personal biography (growing up in Russia, Chernobyl family history), philosophical reflections on love and death, and ethical questions about human–AI relationships.
