nicely put! many aspects of text at least historically have much to do with its materiality (also in a cognitive development sense, learning how to write etc.). what we can think about nowadays is that text and speech might not be a necessary materiality of language. language might depend more on conceptual systems. more like a substrate of intelligence and that might as well be nonhuman (to stay on topic).
