Btw, is it very hard to read and make sense of these texts for native speakers too? Even in my first language these stories sound unlike just a foreign speech, as if not only languages diverged with time, but the whole concept of speech (writing at least) evolved and became more clear in our time, imo.

Interesting if that affected general development and progress and how will future languages look like, or it was the other way round. I guess it may e.g. become even more logical and circumstantial in structure and remove obvious uncertainties (like “do not X and Y” can mean “do” or “do not” to Y) in favor of cfg-ness.
