[Question] What type of Master’s is best for AI policy work?

80,000 Hours recommends a few different flavors of Master’s as entry points into working on US-oriented AI policy: security studies, international relations, public policy, and machine learning.

Does anyone have opinions on which of these types of programs is the best to focus on?

(Clearly a large part of this revolves around personal fit, but perhaps some of these are much more relevant than others in a way that dominates personal fit considerations.)
