One of the major teachers in town is an Italian guy who left his academic high level path for tango. The follower in my profile picture has been a visiting professor at MIT (not sure of the exact title). She never left her academic path for tango but has written about it and still at age of 80+ is my wildest follower; a valuable trait when we explore new areas of movements!
Very well written article. However, everybody doesn't want the same thing from tango. Some are afraid of close embrace and connection. Others use a milonga to fulfill their dream of being a show dancer, at least based on what they lead.
I agree that doing NOTHING but doing it WELL can be rewarding.
