Authors will probably evolve to use AI in their writing process. Maybe they'll write some key scenes and an outline, look at the options chatgpt spits out for the scenes they're having trouble writing, select and tweak passages. Maybe seeing the options will spark new ideas. Either way, AI can only work off of data that it was fed. I am actually really curious to see what an AI trained on extremely prolific writers like Terry Pratchett or Stephen King would come back with, but there will always be a need for an author's sense for good writing and the overall flow of the piece.

Presumably the same arguments about training sets and compensation will also happen with prose. For the record, I do think non public domain artists should be compensated in some way for having their work used in a data training set. Doubly so if it's a set that's exclusively their work (ie. telling AI to generate a painting in the style of Greg Rutkowski).
