30 to 40ish in my experience. Current state of the art seems to lack thinking well about programming tasks with a layer of abstraction or zooming out a little bit in terms of what might be required.
I feel like as a programmer I have a meta-design in my head of how something should work, and the code itself is a snapshot of that, and the models currently struggle with this big picture view, and that becomes apparent as they make changes. Entirely willing to believe that Just Add Moar Parameters could fix that (but also entirely willing to believe that there's some kind of current technical dead-end there)
