This is how progress (in developer productivity) has always been made. We coded in assembler, then used macros, then a language like C, Fortran, then more of Java/Go/Puthon/Rust/Ruby et al. A developer writing a for loop over a list in Python need to necessarily know about linked lists and memory patterns because Python takes care of it. This frees up that developer from abstracted details and think one level closer to the problem at a higher speed.

LLMs _can_ be a good tool under the right hands. They certainly have some ways to become a reliable assistant. I suppose in the way of LLMs, they need better training before they can get there.
