The Winograd Apostasy
Winograd's late-1970s intellectual defection from AI to Heideggerian phenomenology—the 'first high-profile deserter' walking into philosophy after building the field's most celebrated natural language demo.
Between the mid-1970s and 1986, Terry Winograd—builder of SHRDLU, MIT's star natural language researcher—underwent what the AI community experienced as betrayal: he left the field's foundational assumptions for Continental philosophy, specifically Heidegger's phenomenology. The transformation was catalyzed by two encounters: Hubert Dreyfus's systematic critique arguing that human intelligence is embodied and situated in ways formal computation cannot replicate, and Fernando Flores's positive alternative grounded in speech act theory and organizational coordination. Their 1986 collaboration, Understanding Computers and Cognition, argued that 'one cannot construct machines that either exhibit or successfully model intelligent behavior'—a claim so sweeping that the AI establishment received it as apostasy from one of its own champions.

The social cost was real. Winograd was accused of abandoning productive research for philosophical obscurantism. Heideggerian vocabulary—Zuhandenheit, Vorhandenheit, Geworfenheit—was treated as pretentious obfuscation by researchers fluent in predicate calculus. The argument that computers could not model intelligent behavior was interpreted as counsel of despair. John Markoff called Winograd
