I misunderstood your point. I thought you found it remarkable that we expected to be able to discern gender quite quickly. In any case, I don’t know how much our gendered language indicates our values as a society, probably that gender is just information-dense (lots of behavior correlates strongly with gender) such that many languages evolved gender as a utility (and indeed English actually lost much of its grammatical gender though probably not because the density of information was lower in English-speaking societies, but rather due to massive influxes of non-native speakers which had a broader simplifying effect on the language).
