I opened the video in the background and immediately recognized the person: the author behind the 3Blue1Brown YouTube channel. It has a long series of video regarding various mathematical topics which are rather accessible.
My favorite by far is a "proposal" for an alternate notation which makes much more sense and, if adopted, would make mathematics way less intimidating (Triangle of Power (2016), 3Blue1Brown - https://www.youtube.com/watch?v=sULa9Lc4pck ).
I'd give him a Fields medal (or at least an honorary mention of some sort) :-]
