Exactly, maybe "prompt engineering" is really a skill, but the reward for getting better at this is just pumping out more features at a low skill grade. What's excited about this ? Unless I want to spend all my time building minimum viable product.
Prompt engineering is just writing acceptance criteria; it's moving from someone who writes code to someone who writes higher level feature descriptions. Or user stories, if you will.
Thing is though, many people don't know how to do that (user stories / acceptance criteria) properly, and it's been up to software developers to poke holes and fill in the blanks that the writer didn't think about.
