Hubert Dreyfus (1929-2017) was an American philosopher and professor at the University of California, Berkeley, who emerged as one of the most influential critics of artificial intelligence and computational approaches to human cognition in the 20th century. Known affectionately as "Bert" to his students and colleagues, Dreyfus challenged the prevailing assumptions of early computer scientists who believed human intelligence could be reduced to formal rules and representations.
Dreyfus's intellectual journey began in the 1950s when, as a young philosopher trained in the phenomenological tradition, he encountered the bold claims of early AI researchers at MIT. While others celebrated the seemingly limitless potential of computers, Dreyfus recognized a fundamental flaw in their approach. Drawing from philosophers like Martin Heidegger and Maurice Merleau-Ponty, he argued that human intelligence was inherently embodied, situational, and resistant to formal representation—insights he would later develop in his seminal 1972 work "What Computers Can't Do."
Throughout the 1960s and 1970s, Dreyfus became both celebrated and vilified for his prescient critiques of AI limitations, earning the nickname "the prophet of the limits of AI." His arguments, initially dismissed by the computing establishment, gained vindication as early AI projects failed to deliver on their promises. Perhaps his most enduring contribution was his "five-stage model of skill acquisition," developed with his brother Stuart, which demonstrated how human expertise progresses from rigid rule-following to intuitive mastery—a process that resisted computational modeling.
Dreyfus's legacy extends far beyond his AI criticism. His interpretations of continental philosophy, particularly his readings of Heidegger, helped bridge the gap between European and Anglo-American philosophical traditions. His teachings influenced generations of thinkers, and his insights into human cognition continue to resonate in contemporary debates about artificial intelligence, embodied cognition, and the nature of human expertise. As AI again promises human-level intelligence, Dreyfus's fundamental question remains hauntingly relevant: Can human understanding truly be captured by computational processes, or does our embodied existence suggest something more mysteriously profound about the nature of intelligence itself?
