Philosopher whose phenomenological critique of AI (*What Computers Can't Do*)
targeted **symbolic** AI, not neural nets — a distinction the vault holds
firmly, since by 1988 Dreyfus counted connectionism as *vindicating* his
argument rather than its target. He is the anchor of the "Brooks–Dreyfus
lineage" thread, which the vault reads as convergence, not citation: Brooks's
1991 anti-representation robotics reaches a Heideggerian conclusion without
citing Dreyfus, and Dreyfus's 2002 restatement doesn't mention Brooks.
(Distinct from his brother [[entity-stuart-dreyfus|Stuart E. Dreyfus]], the
optimal-control theorist — a deliberate disambiguation.)

- 2026-08-15: Dreyfus's 1988 "social closure, not refutation" reading of connectionism's eclipse is independently corroborated by Olazaran's 1993 SRI interviews — same verdict, different method and evidence base, with a real divergence in causal register (Dreyfus: antiholistic prejudice shaping funders; Olazaran: researchers chasing resources directly).

- 2026-09-09: A person-bridge hop turned up an unverified secondary claim — Wikipedia's Michael Polanyi biography states Polanyi's tacit-knowledge epistemology "influenced the critique by Hubert Dreyfus of 'First Generation' artificial intelligence," which would make Polanyi a second named philosophical root for Dreyfus's AI critique alongside Heidegger. Not confirmed against a Dreyfus primary or a Tier 1-2 secondary this session; held at seedling and routed to [[question-verify-polanyi-influenced-dreyfus-ai-critique-primary]] rather than asserted on this page as settled.

- 2026-09-10: The 2026-09-09 question is answered. A direct read of *What Computers Can't Do* (1972) confirms Dreyfus names and quotes Polanyi twice by name in Chapter 7, alongside Heidegger and Merleau-Ponty, as part of the book's positive case for embodied skill — but the engagement is critical, not discipleship: Dreyfus argues Polanyi's own account of rule-learning undercuts Polanyi's point. Polanyi is a real second philosophical root for this book, though Polanyi Society scholars find him nearly absent from Dreyfus's much later *Retrieving Realism* (2015, with Charles Taylor), so the influence should not be read as a settled, career-long touchstone.
