But the pragmatist in me clearly sees the writing (no pun) on the wall. Technical Writing is an area where ChatGPT and LLMs are going to excel. With tight integrations into Google Docs, Confluence, et al - the next generation of LLMs will be much better and ubiquitous.
That said, the Technical Writers of today can play a big role in using their skills towards Prompt Engineering.
Natural language is quickly becoming the programming language of the future. And this discipline excels at taking nuanced and highly technical topics, then distilling them into easily understood nuggets. Teaching the LLMs as much as possible with the shortest prompt: this is precisely what Prompt Engineering is all about. The task requires elegance and foresight (of how something will be interpret) that even LLMs don’t possess (yet).
In any case, I think their role is more important than ever before - just not in the traditional sense.
