This reminds me of an old Roald Dahl story, "The Great Automatic Grammatizator". A man creates an electric computer that can write short stories in a few minutes (this being written in 1953, when electric computers were just becoming a thing), and starts churning out magazine submissions. Having made a name for himself as a writer (several names, in fact), he then upgrades it to write novels. Finally, he starts offering existing writers the chance to license their names to the machine's works. It's a good read.

Of course, the situation isn't quite the same, largely because unlike the story the magazine here can identify AI submissions, but the similarities are nevertheless interesting.
