Developers definitely need to fit the "be human" requirement - that helps you actually converse with users to find what they need. But wants and needs are different - and you need to be able to find what they actually need/want - not what they think they do. Because otherwise you can create a monster system that is incrementally better than what they already have.

But CS degree type developers shouldn't be overlooked. It is simply not true that "everyone can code" - self taught is not always a good thing. If you're coding anything that needs to properly scale, run on limited hardware etc then you need someone who has a grounding in the subject.
