If an author were to outsource this communication to an algorithm, I'd never read anything from this author again.
It's betrayal, just like outsourcing a phone call to your mother to GPT-3.
It's a waste of everyone's time: The authors time to set up and train the rubbish generation, the CPU cycles and energy wasted, and the reader's time.
Writing is a fine art, and captivating the reader is hard work. The fact that you get bored when reading work by authors that set up the scenery thoroughly might be a sign that those authors stuck to some kind of template for story drafting. There are tutorials and bootcamps for novelists, just like we have coding schools and Create-React-App.
If you get bored by texts created based on templated story layouts, imagine how readers would feel being fed GPT-3 nonsense.
