I don’t know why you’re getting downvoted. i think you hit on an interesting observation.

If all a person had was broca’s and wernicke’s areas of the brain, their abilities would be pretty limited. you need the rest: cerebellum for coordination, prefrontal cortex for planning, hippocampus for memory regulation or whatever (i am not a neurologist), etc.

LLMs might be a part of AGI some day, but they are far from sufficient on their own
