In my view, AI is worst at crossing the rubicon from a 200-line script to a maintainable architecture of ~10kloc.

If you already have a decent architecture, adding a new feature is usually fine. If you have nothing and need it to write a 200-line script, that's usually fine. If you need it to figure out a maintainable architecture that will be easy to extend in the future... that;'s where the problems start.
