Let's look at this scenario:

A simple poem by Li Bai:

床前明月光，疑是地上霜。
举头望明月，低头思故乡。

Artificial intelligence can definitely produce it, just by combining all the simple 汉字 to form a 5X4 matrices. But AI doesn't know which combination is of Li Bai quality. So the computer doesn't know when to stop.

If the parameters expressing the Li Bai characteristics must be input by human agents, then a human Li Bai already exists, thus the AI version of Li Bai is unnecessary.
