For instance, rust doesn't support PAC yet https://github.com/rust-lang/rust/issues/73628. Support for PAC wasn't even in upstream LLVM for a while (it now is, but lld still doesn't support it).
Funnily enough, I have the exact opposite problem, where Google likes to give me results in the configured main language even when I do queries in another and actually want results in the other language.
I’ve found it quite unsettling to be served foreign language videos on YouTube automatically dubbed over by Google into English. Just mixed in with the search results.
It's quite unsettling to be served English AI-dubbed videos randomly on Youtube, where the original is another language you normally default to (Japanese) and it's happy to use in most cases. And then you go to the settings for the video to go back to the original and it tells you it is... Chinese (and no, it's really Japanese).
rqlite[1] author here. Just to be clear, rqlite is not SQLite but rewritten in Go. rqlite uses the vanilla C code, and calls it from Go[2]. I consider that an important advantage over other approaches -- rqlite gets all the benefits of rock-solid[3] SQLite. As result there are no questions about the quality of the database engine.
That would be interesting for sure, but considering you don't hear yourself the same way someone else or a mic does, I'm not sure it would have the benefit you're expecting.
