I think it could go either way depending on the product. For example in app/game/web development where code quantity > quality, hire more juniors who can bust out code with ChatGPT all day. But if you're developing software for medical devices, vehicle control systems, HFT, etc. Then nobody's going to let some college grad using ChatGPT touch it. You'd hire senior engineers who can be responsible for the reliable operation of the software and they can use ChatGPT for code review, test suites, etc.
