I mean, right now the only thing at risk is the todo.app industry...
I've yet to see anything maintaining legacy apps, or generating line of business apps with requirements... even simple stuff, like departure needs to be before arrival, etc.
I do see a whole bunch of youtube videos about generating a whole codebase, but it's the kind of stuff that there's a hundred tutorials covering.
Let me know if you have a chance to try it out.
Here is a chat transcript [1] that illustrates how you can use aider to explore an existing git repo, understand it and then make changes. As another example I needed a new feature in the glow tool and was able to make a PR [2] for it, even though I don't know anything about that codebase or even how to write golang.
