I’d say there virtually must be an upper bound. As to where this upper bound is, you could do the following back-of-the-napkin calculation.
ChatGPT is pretty good at reading and writing and it has something on the order of 100 billion to 1,000 billion parameters, one for each artificial synapse. A human brain has on the order of 100,000 billion natural synapses and a chimpanzee brain has about a third of that. If we could roughly equate artificial and natural synapses, it seems that a chimpanzee brain should in principle be able to model reading and writing as well as ChatGPT and then some. But then you’d have to devise a training method to set the strengths of natural synapses as desired.
