Professors are terrible managers, leaders of supervisors. Their ego is greater than the vision they may potentially have for whatever projects they are doing. Their main aim is to use your labor as a resource to increase their fame, NOT TO HELP YOU GROW. in fact, because they feel threatened by your youth, talents, creativity and curiosity, they must push you down, so they can remain on top. I DO NOT recommend anyone with a degree of self-worth and thirst for their future to work for a famous professor at Stanford research facilities.
EVERYTHING ELSE - The commute, the lack of parking space, the cost to park, the work environment, the red tape, the politics, their ego.
