> Just look at the quality you get from asking teenagers (or even college students!) to prepare presentations. The counterpoint is that those teenagers suck because they missed out on years of practice because they were never given the opportunity to actually teach anyone anything meaningful before. You are also presuming a high-stakes situation where mistakes are costly and go uncorrected forever. That is not realistic. Well-educated teachers are still vital, and a lesson gone bad presents even more teaching opportunities than a lesson gone well.
