I get the impression that the software scenarios where LLMs do the best on both reliability and time-saving are places where a task was already ripe (or overdue) to be be abstracted away: Turned into a reusable library; as as a default implementation or setting; expressed as a shorter DSL; or a template/generator script.

When it's a problem lots of people banged their head against and wrote posts about similar solutions, that makes for good document-prediction. But maybe we should've just... removed the pain-point.
