Two challenges.
1. The client's A' uses many of the same domain terms of A, but with different, more precise definitions.
2. The client's A' introduces new language that sounds like A, but isn't at all.
What would chatGPT do?
I can't post the exact prompts & responses as they wouldn't mean much to someone who was not both a domain expert in A' *and* A.
But tl;dr? Much hilarity ensued.
