Are you saying this based on the fact that no-one will read or understand the code manually? That might be the case but on some areas, having a product understanding and knowing what to build, why to build matters a lot and sometimes the LLMs will write code that is not correct, doesn't make sense and they will continue down that path without explaining it.

I still believe that other languages which are understood by developers are and will be required and LLMs are trained on the same dataset so it can write the code.
