Cognitive load has nothing to do with your ability to "easily onboard". If you can't understand German, would you say that usage of German increases one's cognitive load? No, that would be preposterous. If you need to speak in German, then you hire Germans or people willing to learn the language. Onboarding might be a challenge, but it wouldn't have anything to do with the performance of those that do know German. I myself speak English as a second language, because I had to learn it in order to do my job. Seeing you're from NYC, there's a high probability that English was imposed on you from birth. Good for you given our profession, but a lingua franca is context sensitive, temporary and English isn't even the second most spoken language. And do you know what language is more universal than all natural languages and that doesn't change much? Math. And math uses symbols, not English words. And Haskell is much closer to math than all mainstream languages.
