It is all about haptic feedback, and low latency between action and outcome.

You can twist virtually with good precision. But, what is much harder is the feel, state of the knob, particularly when it is released and then gripped again.

Mechanically, the structure of the knob can take some energy input, and it serves as a mechanical pivot, or fulcrum, depending on how people use a knob.

Without all those physical things, people lack the complex frames of reference needed for fine, "thought is action" type control.

This is especially true in environments where gloves are worn.

In addition, the essential ship controls must work in rough weather, so you want something you can grasp to keep your hand steady. So long as airplanes have human pilots, I do not suppose the physical stick, rudder pedals and throttles are going away.

Yes. And state comms. Where that input device is matters.
