Unless your company is investing in actually teaching your junior devs, this isn't really all that different than the days when jr devs just copied and pasted something out of stack overflow, or blindly copied entire class files around just to change 1 line in what could otherwise have been a shared method. And if your company is actually investing time and resources into teaching your junior devs, then whether they're copying and pasting from stack overflow, from another file in the project or from AI doesn't really matter.

In my experience it is the very rare junior dev that can learn what's good or bad about a given design on their own. Either they needed to be paired with a sr dev to look at things and explain why they might not want to something a given way, or they needed to wind up having to fix the mess they made when their code breaks something. AI doesn't change that.
