why golang lost to rust ?

  Either would have worked, but rust's fussy compiler & memory features is an advantage for LLMs. The more bug catching you can shift out of runtime and into compile time the better since the LLM can fix it

    go is even more straightforward for llms imo. It's a dead simple language with a good garbage collector, where you can still do a lot memory management

    Simplicity is a feature too.
    > you can still do a lot memory management
    That’s kinda my point - you don’t really want to trust the LLM to get any sort of memory management right. A system where hard constraints are baked into the language itself and the LLM fights the compiler at compile time removes a lot of hoping the LLM got it right.
    Ultimately either works though so use whatever you enjoy
