> The need is that writing is expensive.

That's the thing, good writing is expensive, massively so, much more than people think.

Letting the machine do the writing however shows us that many people have no idea why writing is expensive, nor do they respect that perhaps it needs to be expensive. Communication is incredibly hard, very few master it. I'd even go so far as to say that clear, precise and readable communication is so hard that we do not have sufficient training data to build an LLM that can do it.

Letting a person write article, like this one, doesn't necessarily improve the quality, but it does show us that some thought and effort have at least been put into it. There was a cost and you deemed that cost worth it for conveying your message. Without the cost there's nothing stopping you from wasting peoples time.
