The point of eventual “all-code-is-written-by-AI” is that it really does not matter if your code is maintainable or not. In the end, most of the products are written to accomplish some sort of a goal or serve a need within a given set of restrictions (cost, speed and etc.). If the goal is achieved within given restrictions, the codebase can be thrown away until the next need is there to just create everything from scratch, if needed.
