I never said langchain "removes the value of learning to write prompts". My point is it abstracts it out enough that not everyone working with LLMs will need to know how to do it at a very high level. Just like most programmers can't write assembly/C, but we have tools which abstract it out so that experts can write/generate it for us. I don't know about SQL and ORM to respond to your analogy.
