A couple of reasons for that. Knobs and switches provide better tactile feedback, allowing you to look at things other than the controls when you operate them.
Considering the sheer, overwhelming amount of information you have to take in with your eyes, diverting your eyes away from that information and to the controls in order to operate them is just a Bad Idea. That's why all-touch keyboards haven't been implemented already -- touch typing is easy, but not if you don't know which keys your fingers are placed on... you know... by feeling
the keys under your fingers.
