In the 5 minute interview video, he mentions that the most exciting uses for math are learned in college and that grade school math is very dry because the students don't see what it can be used for. However, the article says that his focus is on pure math, which doesn't necessarily lend itself immediately to real world application. I'm wondering what his opinion is on how to encourage a love for studying abstract/pure math in spite of not seeing how it can be applied immediately.
