There seems a fair enthusiasm in the UI of these to hide code from coders. Like the prompt interaction is the true source and the actual code is some sort of annoying intermediate runtime inconvenience to cover up. I get that productivity can be improved with a lot of this for non developers, just not sure using 'code' as the term is the right one or not.
Yes, the code is still important. For example, I had tasked Codex to implement function calling in a programming language, and it decided the way to do this was to spin up a brand new sub interpreter on each function call, load a standard library into it, execute the code, destroy the interpreter, and then continue -- despite an already partial and much more efficient solution was already there but in comments. The AI solution "worked", passed all the tests the AI wrote for it, but it was still very very wrong. I had to look at the code to understand it did this. To get it right, you have to either I guess indicate how to implement it, which requires a degree of expertise beyond prompting.
