Seriously, flying has a thinking side to it that AoA represents an essential part of and as a subject matter it is both fascinating and rewarding. The theory runs deep on this, well into high college level courses like low and high speed aerodynamics, aeroelasticity, aircraft design and optimization, hydrodynamics, flight dynamics, simulator design, computer flight modeling, model aircraft, glider and helicopter design, engine design, aerobatic and military flight, so many high level topics. To put one small instrument in the cockpit is not asking much if you are aware of how many things are dependent on it. It may not be required to watch AoA in some aircraft, but it matters in all aircraft whether the pilot thinks about what's going on or doesn't.
My two cents worth and to the quick (being that AOA was beat into and ingrained in me): It adds important adjutant information (as long as you get proper training and understand its purpose) in helping to avoid stalls. I feel GA pilots can benefit greatly in the proper use of this indicator in order to cut down on the over abundant and seemingly inevitable stalls that result from losing control inflight. It never affected my instrument scan etc.
