Should we overhaul all languages that use gendered language? I speak French and often think in French (le/la, etc), obviously I speak English, but a lot of modern English comes with heritage from cultures, languages, hell even concepts of thought (yes thinking in differently languages gives unique perspectives of the world).
Of all the most useful projects to humanity (diverting asteroids, developing free energy, curing cancers, solving childhood poverty, etc) in any top-3 list I'd put "having a single common language that is super-simple to learn and master and which everybody is taught from childhood".
Let's not change English or French then, but leave them as "classical" languages, but teach kids the new easy/expressive/explicit one. No gendered nouns, no phrasal verbs, no reported speech markers, etc.
Completing this initiative makes all the other ones easier to complete. And it's not like it's much more complicated than the other complicated things we donate to and try to push forward every year.
