In this article, we delve into the world of artificial intelligence by celebrating the 60th anniversary of Eliza, the very first conversational agent developed by Joseph Weizenbaum. Eliza paved the way for a new form of communication between man and machine, marking a major turning point in the development of modern chatbots. We will explore how it works, its legacy, and the implications of its existence in today’s digital world.
The Origins of Eliza
Developed between 1964 and 1966 at MIT, Eliza is considered the pioneer of chatbots. Joseph Weizenbaum, its creator, conceptualized a program capable of simulating human conversations. By using electric typewriters connected to a central computer, users could interact with Eliza. This rudimentary system posed questions and reformulated the speaker’s statements, thus mimicking a conversation. The most widely used script was titled “DOCTOR,” where Eliza simulated a psychotherapist based on the work of Carl Rogers, an American psychologist known for his nondirective approach.
The Functioning of Eliza
Eliza relied on a simple analysis of keywords and patterns present in the user’s speech. For example, if a user stated “I am not happy,” Eliza might respond: “Can you explain what makes you unhappy?” It did not seek to provide precise answers but rather to encourage the user to continue the conversation. Although Eliza’s functioning is extremely basic compared to modern agents, its approach created an illusion of engagement and understanding.
The Eliza Effect
This concept, known as the Eliza effect, refers to the tendency of users to project human characteristics onto computer programs. Despite its lack of true understanding, many users ended up opening up to Eliza, sharing personal information as if they were conversing with a real therapist. This phenomenon has sparked reflections on the relationship between humans and machines, and on how users attribute emotions and personality to a simple algorithm.
Eliza in Popular Culture
The name Eliza is directly inspired by Eliza Doolittle, a character from George Bernard Shaw’s play Pygmalion. In this work, Eliza Doolittle, a flower girl, aspires to join high society by improving her speech. Weizenbaum used this reference to highlight the limitations of machines when faced with human complexity. Just as Shaw’s character does not truly become a lady by merely learning refined speech, Eliza was not designed to replicate the depth of human interactions.
Eliza Today and Its Legacy
After sixty years, Eliza’s impact remains profound in the field of conversational agents. Modern systems, such as chatbots based on advanced language models, owe much to this initial invention. They have become increasingly capable, able to simulate much more nuanced exchanges, particularly thanks to the evolution of artificial intelligence technologies. Today, even programs like ChatGPT maintain the illusion of a real conversation, thereby reinforcing the Eliza effect.
The Pitfalls of Conversational Agents
As technology progresses, concerns are emerging regarding the excessive use of conversational agents, especially among young people. Experts, as well as associations, are sounding the alarm about the risk of developing an illusory emotional bond with these systems. In 2024, a report from the CNRS highlighted the potential dangers associated with this new form of interaction. Weizenbaum himself, aware of the ethical implications of his invention, had warned against the possible pitfalls of artificial intelligence.
Eliza Resurrected
Recently, scientists have brought this pioneer back to life by reactivating the Eliza code found in the MIT archives. This digital resurrection allows us to question the extent to which current technologies have evolved while remaining linked to their heritage. Constant advancements in artificial intelligence raise questions about our relationship with technology and about human nature.

Conclusion Without Conclusion
As Eliza celebrates its 60th anniversary, it is not merely a relic of the past; it still raises pertinent questions about the future of interactions between humans and machines, and about how these exchanges redefine our relationships.
