Although it may seem a little strange and hard to believe, before virtual assistants like Siri and Alexa there was a 20th-century speech program, He had the ability to react the same way as humans.
ELIZA was a ‘chatbot’ created by Massachusetts Institute of Technology (MIT) professor Joseph Weizenbaum in 1966.. This intelligence was one of the first programs that could maintain a conversation with a human user.
Based on the psychotherapy method of psychologist Carl Rogers, the computer scientist created a technology that can carefully and empathetically answer any question.

According to the BBC, to ensure fluency in speech, the engineer programmed Eliza to be able to distinguish speech. keywords that will allow you to give answers on the subject theme enthusiasm.
For example, if the user types “I feel frustrated,” ELIZA will respond with “Why do you feel that way?”, a system equal to or similar to the existing ChatGPT. he might reply.
This was also possible, because it stores predetermined statements about different things, which helps the child recognize key conceptsand thus ensures the continuity of the virtual conversation.
However, according to the media mentioned above, the chatbot had some limitations, such as its inability to memorize conversations and learn from its communication with people.
This ahead-of-its-time project helped rethink many other existing AI systems. such as ‘chatbots’, virtual assistants and autonomous vehicles.
According to Gilles Paul Pieffet, biophysicist and researcher at the University of Antonio Nariño, This system demonstrated the power of pattern matching to match keywords with user input.

“Classical AI led to advances in search and computational logic and achieved early successes such as your ability to understand and respond to human languagean important challenge that helped develop subsequent prototypes,” says the expert in his article titled ‘Artificial intelligence: past, present and future’.
