The Guardian's long-read podcast revisits a 2023 piece by Ben Tarnoff about Joseph Weizenbaum, a pioneer who witnessed the birth of AI. Despite building ELIZA, an early program that simulated human conversation, Weizenbaum grew deeply alarmed by how people projected human emotions onto machines. He argued that there are fundamental aspects of human thought and feeling that computers can never replicate, warning society against blindly trusting technology over human empathy and judgment.
