Researchers revive world's first chatbot ELIZA from 60-year-old code

The original chatbot "ELIZA" has been revived from 60-year-old code by researchers. They used old printouts from MIT archives to restore the program, which was created by MIT professor Joseph Weizenbaum in the 1960s. ELIZA was designed to interact with users and influenced modern artificial intelligence. The code was initially written in a now-obsolete programming language but later adapted into Lisp, which gained popularity online. The revival was made possible when researchers discovered the original code among Weizenbaum's papers, which many believed to be lost until 2021.
