LLMs are great at translation. That's why language translators were among the first professionals losing their jobs to AI.

anecdotally this has been a huge help for my projects. I'm seeing AI one-shot porting from one library/framework to another with very minimal handholding. It used to be that these decisions needed to be thought through a lot because they were hard to change later on

It's foundations all the way down. The difference is people have reality as our reinforcement learning environment.
