How did English become the most widely spoken language? Most certain through far more bloodshed than anything to do with the production of AI systems. If Rust's association with AI is a reason to avoid using Rust, then yes, the social conditions surrounding English usage are sufficient grounds for a movement away from English as the lingua franca.
Anyway, like I said in my comment, you can replace "English" with any other language that LLMs speak fluently. I gave English as the example language because that is the language this forum is in. There are much less widely spoken languages that LLMs are also fluent in. Should users of those languages abandon their languages? I was responding to that person's ridiculous reasoning.
