I honestly don't think we've had good LLMs and experience in using them for long enough to make that kind of call yet. How do you know what you're getting isn't just lots of tech debt, for instance?
I agree there appears to be a great potential where this becomes a force multiplier reducing the need for the more experienced engineers to sit on top. To other sibling comments, yes we need better methods for managing tech debt with these emerging tools but that doesnt make OP wrong.
