For those interested in the history, this is in fact the Neural Network research path that predated LLMs. Not just in the sense that Hinton et al and the core of the "Parallel Distributed Processing"/Connectionist school were always opposed to Chomsky's identification of brain-thought-language, but that the original early 2000s NSF grant awarded to Werbos, Ng, LeCun et al was for "Deep Learning in the Mammalian Visual Cortex." In their research program, mouse intelligence was posited as the first major challenge.
