Haha ehhh I think you're reading into this a bit too much. It is possible to love more than one thing - I love helping educate people and doing it at a scale that Khan Academy can provide. I also love building reusable JavaScript libraries. I also love building tools for Art Historians. They all shouldn't be to the exclusion of each other and, in fact, there's often overlap. Part of the fun in life is embracing that and trying to make the most of it!
