> Why would "creating a novel" by a human not itself be text generation based on prediction on what are the next good choices (of themes, words, etc) based on a training data set of lived experience stream and reading other literature?
Unless you're Stephen King on a cocaine bender, you don't typically write a novel in a single pass from start to finish. Most authors plan things out, at least to some degree, and go back to edit and rewrite parts of their work before calling it finished.
Sure, but if we're talking about editing an entire book eventually the fine details do matter. That, and presumably human authors' abstraction/memories of their books are stored in some more compact form than language tokens. Though we can't be sure about that.
