The same could be said for a lawyer or an author or someone else that uses language as a profession. Knowing the language is not enough to know how to use it to get the things you want/need. There is a lot more to "programming" than just writing code.

What is a programmer? I would say in the most naive understanding of the term it is someone that inputs instructions for computers to perform. Who's to say that a Natural language isn't just another obfuscation on computer programming languages? As is, no programmer is writing raw machine instructions, we are all using languages built on top of each other (usually) multiple layers deep. I don't see current "AI" as being anything more than another abstraction.
