I agree that high turnover is a real constraint. That’s why the answer isn’t “10 years of apprenticeship” but designing scaffolds that combine learning with contribution in a shorter timeframe. Things like short rotations, micro-credentials, or mentorship stipends let juniors add value while they’re still on the job. Even if they leave after a few years, the investment isn’t wasted — both sides still capture meaningful returns.
