Gary Marcus insists recent models are hybrids, blocks user after heated exchange

GaryMarcus · x · 2026-09-04

Gary Marcus clashed with @DarlaSkyee and François Chollet over whether a model is a hybrid system. He conceded neither he nor critics know how it works since nothing has been published, yet insisted "every recent system has been engineered and hybrid."

He then argued that the model invoking symbolic tools alone proves it is a hybrid, calling the user's post "astonishingly ignorant and equally unfair" before blocking them. A notable spat in the ongoing neuro-symbolic architecture debate.
