you can write prompt to clean unstructured text into structured text. that becomes the work area.
instead of asking gpt "write me some code in pyton that does x" you can just tell gtp "do x with the structured data in the work area and present a structured result"
gpt becomes the computation engine
granted it's super expensive and quite slow, today
but with a few plugins to take care of mechanical things and the token memory space becoming increasingly bigger, writing the programming step directly on there may be the standard. as soon as vector storage and reasoning steps gets well integrated, it's going explode.
