I trust me more than my camera and once I have the good setting I don't have to change so often.
And also if I want something really precise or a special effect (speed, static, blur background) I can only rely on me. That's the challenge and that's why you can only do it with semi-pro or pro cameras.
It's like a driver with his car, he chose between adapting himself or adapting the car.
But It's sometimes so difficult we can prefer the comfort of automatic.
