I wonder if "prompt engineering" will be replaced by improvements to LLMs within the next couple years and this is just a bad DX step gap along the journey
Short version: I think prompt engineering will be an important skill for a very long time. Using these systems to the maximum of their (currently unknown) potential will always involve expert knowledge!
You can say whatever you like and live with the results, or try to phrase your communication in a way that elicits the kind of response you want from the other party.
We’ve engineered it away with computers where we learn a programming language or the rules of an operating system and the acceptable input is translated into a deterministic result.
But natural language is much more creative and open ended.
