LLMs have been getting worse at long-form prose recently (and they were never good at it to begin with.) They're good at writing software because writing software is a much more restricted domain.
(And I have a more weakly held belief that even if we do all die, Claude 3000 will still be thinking stuff like "Burning off Earth's atmosphere was the point that earns its keep." They just aren't optimizing these things to write legibly.)
