I’d add to this insightful post that the reason AI has “line blindness” is because it cannot parse the ineffable. In the Cormac McCarthy excerpt, why is “sheetlightning quaked sourceless” better than the grammatical adverb “sourcelessly” or “sourceless sheetlightning quaked”? Because to put “sourceless” at the end more effectively evinces a sense of powerlessness in the observer than the other two options. Most of the time, emotional writing is not about people hugging or crying.
