Vergecast: ELIZA, the world's first chatbot
Aug 12, 2026 · 40m
Summary
Host David Pierce discusses the history of Eliza, the 1966 chatbot created by Joseph Weizenbaum, with co-authors David Berry and Mark Marino. They explore how this primitive program convinced users it was human and how Weizenbaum’s subsequent critique of AI in "Computer Power and Human Reason" remains relevant. The conversation draws parallels between the original "Eliza effect" and modern LLMs, highlighting the dangers of commercializing artificial intimacy and the critical distinction between calculation and human judgment.
