The presentation of Edward Frenkel of Langlands Program is why I love maths: the magic of finding relations between different domains. Edward Frenkel is very good at expressing his fascination with the subject. The Numberphile version (https://www.youtube.com/watch?v=4dyytPboqvE) remains simple, but this is great to have such a presentation on this well-known popularization channel. The version of the Abel Prize Lectures (https://www.youtube.com/watch?v=b8e_HMEwKIY) is less simplified and give a little more information.
