You're going further to "whether LLMs can be useful when programming in a new programming language." Which I will leave to developers using those new languages.

You're going further to "whether LLMs can be useful when programming in a new programming language." Which I will leave to developers using those new languages. I'm saying more that every time developers develop/find a tool that makes them more productive, if it doesn't look like the Old Ways, there will be other developers to crap on them and say they don't know enough about the Old Ways. Which may or not be true but isn't always relevant given the size of the space that comprises modern programming. This is why there are still people who deride programmers who use IDEs instead of using tools that were invented nearly 50(!) years ago. I'm not saying either way is a fit for every use, but the attitude that developers should eschew attempts to improve the state of our tools is toxic.
