These days I'm most interested in economics and politics because I believe that our most important problems right now are in this realm (eg. poverty, job automation, healthcare costs, housing prices, college prices). The Javascript framework wars are laughably insignificant compared to these problems, yet unlike web development, there aren't enough logically-minded people really tackling these problems. Unfortunately there's probably no job out there that I could realistically obtain that would pay me to work on these problems, thus I'm just saving money for retirement and learning on the side.
