The "Rewrite it in Rust!", all gas, no brakes zealotry predates LLM coding agents. When you dismiss the trade-offs with no consideration, and abide no questions about the possible cost of the "one true $X", you're practicing religion, not engineering. What has changed is the zealots no longer restricted to demanding that other people adapt their preferred language, but can now automate forking projects into their ideal language. I'm hoping the next shoe to drop is the realization that the language is a small part of a projects success, when it's time to maintain their forks.
