An attempt to modify the already generated specific piece of code or the program in general will produce an unexpected result. Saving some money on programmers but then losing millions in lawsuits or losing customers and eventually the whole business due to an expected behaviour of the app or a data leak might not be a good idea after all.
If you're pushing unreviewed, untested code to production, that's a bigger problem than the quality of the original code
And how do they build the knowledge and skill needed to review and test without being practiced?
* sounds like next quarters problem
* since everyone is doing it, sounds like it will be society who has to figure out an answer, not me. (too big to fail)
Not joking, I think those are the current defacto strategies being employed.
Here's a nice litmus test: Can your AI take your code and make it comply with accessibility guidelines?
That's a task that has relatively straightforward subtasks (make sure that labels are consistent on your widgets) yet is still painful (going through all of them to make sure they are correct is a nightmare). A great job to throw at an AI.
And, yet, throwing any of the current "AI" bots at that task would simply be laughable.
