Based on the LLM-produced stuff I've seen online I have to think a market will emerge soon for real writing from actual people. How much reshuffling of stuff already written a hundred times can we put up with? The bar seems pretty low if you only have to compete with ChatGPT.
The problem might be quantity over quality. If the quality is only half as good but the AI can put out orders of magnitude more material faster, that could be the direction that may be preferred by some content publishers.
We can easily measure quantity, but how do you define or measure quality when it comes to writing, or imitation of writing?
