As a teacher one of the most powerful comments from this was in talking about the measure of a person/mathematician: " Make personal evaluations, don't rely on numbers and try to use a more holistic approach." Highlighting for me that students should never become their assessment results, reduced to a number alone!

His point about needing good mathematics teaching at every level sounded very positive too, particularly combined with the "Learning recipes is not a good way to learn mathematics" - how true!

A fabulously interesting interview, thank you.
