I'm not at all worried about AI taking over software development. In all likelihood, what you'll see instead are AI plugins in IDE editors which just assist in a much more advanced way than the intellisense we have now. Having machines code out the business logic is very much so something that would be less efficient than having a person do it.

Realistically, it just means that, rather than your coworker code-reviewing you and making a handful of comments, you get a machine to do that, and get two or so comments from your coworker about the business logic.

To answer your question: never.
