While this matches my experience, it's worth mentioning thar the act of breaking a task up into the correct chunk size and describing it in English is itself a non trivial task which can be more time consuming than simply writing the actual code.

The fact that it works is amazing, but I'm less convinced that it's enhancing my productivity.

(I think they real productivity boost for me is if I still write the code and have the assistant write test coverage based on diffs, which is trivial to prompt for good results)
