This is a good suggestion. I've read a few article about this Langlands programs, and just like the theory of everything for physics, there's just too many things to get good at before one can get a grasp of the subject.
By systems theory, you mean the "emergentism"? I've sit-in a class once in complex systems, and I was convinced by that time that, maybe, all the physical laws we have about have some collective origin. There is a need, now more than ever, a full understanding and ways of modeling systems that spit emergent behavior naturally.
Are we in the same line of thinking?
