Ask HN: I learned useless skill of prompt engineering, how relevant will it be?

I consider myself to be a pretty good prompter. Been using the LLMs for a long time now. Most of the time I manage to get the desired results out of LLM models. Do you think this skill is anywhere useful?

So far it has saved me some time on my work, but I don't think promoting will be any relevant in the near future. People can and will build models that follow the same mode of thought.
