Vergecast: ELIZA, the world's first chatbot

August 12, 2026 · 40 min

Show notes

From The Vergecast, this episode takes a look back at one of the earliest chapters in the history of AI.

Before Alexa and Siri, there was ELIZA. The first chatbot ever was the creation of a man named Joseph Weizenbaum, who built the bot almost as a magic trick — and then couldn't believe how many people fell for it. David Berry and Mark Marino, two members of a team dedicated to restoring and understanding ELIZA, explain how Weizenbaum created the virtual conversant, why he came to regret it, and what ELIZA can teach us about life in the AI age.
