Don't worry, Google will find a way to break it so badly that heavy users will stop using it frequenty. AI translation forced even on those who know the language are just a example of what they fail to understand and don't bother to discuss internally.
At least it's optional.. YouTube thinks if you're accessing from country X, you want the video titles in language X. Utter fucking geniuses. I say "thinks", it sometimes does this and sometimes doesn't. And there's no "Leave the fucking titles alone" option anywhere...
Reminds me of IMDb pulling the same genius move of "Hey, here's the title of that movie as it was released in the region we've geolocated you in!"
