I guess the whole discussion (in 1963, in 2025), is about 'knowledge acquisition' (or lack thereof). He mentions the Brazilian students memorising 'stuff' without understanding - as a former Brazilian educator, I can tell you that when I was working there in 2010-2020, it hadn't changed, and, to my point, got worse in late years. I think a lot of students care about 'getting a diploma' without actually learning something, but my main concern is about fairness: how could I praise good students from 'devious' students altogether?
