Editorial bio
Gary Marcus is the most audible counterweight to the "scaling solves everything" camp. He entered Hampshire College young (BSc Cognitive Science), earned his PhD at MIT at 23 under Steven Pinker (on language acquisition), and went on to publish widely in Science, Nature and the broader cognitive-science literature. Professor Emeritus of Psychology and Neural Science at NYU; founder of Geometric Intelligence (acquired by Uber in 2016), where he briefly directed Uber AI Labs.
His books – The Algebraic Mind, Kluge, Guitar Zero (NYT bestseller), Rebooting AI (with Ernest Davis) and Taming Silicon Valley – run a consistent thesis across two decades: deep learning alone won't get to robust reasoning, hybrid neurosymbolic architectures are undervalued, and the industry is overselling what the models can actually do. He writes the Marcus on AI Substack and has testified in front of the US Senate on AI oversight.
Worth following if you want the counter-case to the AGI-is-imminent position argued with scientific receipts.
