Gary Marcus
Cognitive Scientist, AI Critic & Author
About
Gary Marcus is a scientist, best-selling author, and professor emeritus of psychology and neural science at NYU. He is a leading critic of current deep learning approaches, arguing that large language models lack true understanding and that achieving AGI requires hybrid architectures combining neural networks with symbolic reasoning. He founded Robust.AI and Geometric Intelligence (acquired by Uber), and authored 'Rebooting AI' and 'Kluge'.
Key Contributions
- Argued early and persistently that deep learning systems lack robust abstraction, causality, and compositional reasoning
- Advocates hybrid neurosymbolic architectures as a path beyond pattern matching alone
- Linked AI arguments to earlier cognitive-science work in books such as 'The Algebraic Mind' and 'Kluge'
- Founded Geometric Intelligence, acquired by Uber, and later Robust.AI to pursue more reliable AI systems
- Co-authored 'Rebooting AI,' turning technical concerns about brittleness into a public critique of AI hype
- His skepticism has aged well in some failures, but his combative style and repeated near-term critiques have made him a polarizing figure
