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.
Sure, but this is way too much arguing for a minor and harmless statement. You seem to be making a huge deal out of one person on the internet saying that they stopped programming in Rust because they felt that rust projects were getting dominated by LLM output. They weren't advocating for others to do the same. They simply stated a personal choice. I choose to let people make the choices that they want to make and state their reasons for doing so, especially if their choice has no effect on me.
Even the joke meme in their original post wasn't making an accusation towards rust but simply saying that rust use in combination with all the other indicators in the meme (i.e., "I made", "open source", and "in a month") point towards a project being vibe-coded.
