I'd say the individual pieces work fine, as shown by GPT-4, but could always be better. This is something like making a list of things to do for marketing a product. Then for each list, making more detailed lists where needed, and using APIs to carry out actions. Self-improving code is quite similar in terms of process. The whole thing doesn't quite work together too well. But it's more of an integration problem now. This is still in its early phases (only a few months, or less), so I wouldn't say it can't happen.
