Gary Marcus: Judea Pearl's causality challenges remain unsolved in the LLM paradigm
GaryMarcus · x · 2026-09-18
- Gary Marcus amplified a supporter's argument that LLMs lack the causal understanding needed for truly data-driven decisions; real systems should combine Causal AI (Pearl's causal calculus), knowledge graphs, LLMs, agents, business rules, and deterministic code.
- Marcus stresses that Judea Pearl's The Book of Why remains highly relevant: anyone who thinks his challenges have been solved within the current LLM paradigm is kidding themselves.
