That may be generally true, in this case Apple actually has an engineering team in Czechia that works on biometrics and authentication:

I would not be surprised if Apple engineers are more likely to be bilingual than a random person selected from the world's population.

I'm a little impressed with Google. Recently the assistant started understanding when I speak Portuguese or when my wife switches to it in a text message. I hadn't had that experience before, the assistants would pick one language and mispronounce the other.

Alexa has an experimental bilingual mode but it's nerfed by its general failure to understand well.

I use danish and English and I must admit I don’t really encounter issues switching between them on apple or Microsoft operating systems.

Only thing I can think of is some features being available later in danish compared to the English release like the swipe keyboard in iOS.

Netflix can't even auto-translate subtitles (in the age of genai where we are close to generating entire movies from scratch). Let alone ever imagine that you'd want to see subtitles in two languages at once.

Language support is still such an enigma.
