the video is in polish, translation on the cyberpunk 2077 forums:

CDPR about languages in the game

As of yet no decisions have been made, but we're thinking about a system that could tell the world's story. The idea is to record everything in original languages, i.e. if we'll meet Mexicans in the game, they'll be taking -- Mexican slang even, portrayed by Mexican actors. The player would be able to buy a translator implant, and depending on how advanced it is, he'll get better or worse translation.

You can't reliably recreate street slang of Los Angeles or some other American city, you can't simply dub it and reproduce those emotions, rhythm of speech, mannerisms. Everything has to be cohesive. Otherwise we'd simply hear that Polish actors are trying to imitate Americans. That won't work.

I have been trying to get into the 2020 system since the game's announcement, and the character creator is very very well done.

it can help you decide a personality, appearance, ethnicity/language, and events that happen to your character before it even starts. you even have to have a job that bases how much money you start off with.
