No, absolutely not. We will continue to value output that purely shows human thinking and effort.
AI writing is some average over all writing the model was trained on (with some RLHF on top). It is mediocre by definition.
If the context can be above average quality the result should be too as long as the AI is sufficiently smart. Especially if people iterate on the produced work to push it up in quality.
However if you don't have a good topic and don't iterate to improve the result then you get incredibly poor writing.
Say there was a Chinese artist in a room...
Their output does have intrinsic value yes...
