At least for the type of coding I do, if someone gave me the choice between continuing to work in a modern high-level language (such as C#) without LLM assistance, or switching to a low-level language like C with LLM assistance, I know which one I would choose.
Likewise, under no circumstances would I trade C for LLM-aided assembly programming. That sounds hellish. Of course it could (probably will?) be the case that this may change at some point. Innovations in higher-level languages aren't returning productivity improvements at anywhere close to the same rate as LLMs are, and in any case LLMs probably benefit from improvements to higher-level languages as well.
