I don't know, I've always thought that junior problem was mostly non-technical, kids issues: overconfidence, love for shortcuts, sense of entitlement, arrogance, lack of communication and respect of colleagues, including fellow juniors and seniors, aversion to holy wars, lack of compromise and team discipline, disrespect to existing solutions, laziness in following-up post-delivery, negligent edge case checking, being opinionated about tooling, languages and whatnot. Very little of this can be fixed with AI, and many things can be easily amplified. I mean, one junior with AI vs one senior with AI might yield comparable results, but seven juniors with AI vs seven seniors with AI should fail pretty fast.
