In most cases there are vastly more synapses than there are neurons, and beyond that the neurons and synapses are not highly rudimentary pieces but are themselves extremely complex.
It's certainly true that nervous systems do quite a bit more than language processing, but AGI would presumably also have to do quite a bit more than just language processing if we want it to be truly general.
