I appreciate this sentiment and I'll add that, as a writer, I've encountered and experienced it myself and among creative friends.
The notion that a model can produce text, or images, that resemble our output is certainly dispiriting in some ways. But it also is empowering when you realize that what you create, and the way you feel when you do it, is independent of that.
I don't write to put machines in their place - I do it because I like it, and because I want to manifest my ideas in a way that is uniquely my own. I don't really care that a machine may produce a book. That book simply has no value to me and I hope that over time, as the novelty of this form of semantic reproduction wears off, others will share that estimation.
