what makes a good pilot is not good vision, or fine motor skills. Its the integration of the two: hand-eye coordination, muscle memory, a lifetime of experience and familiarization with the traditional controls on aircraft, not to mention a Darwinian process which has selected for those who excel at those skills. The stick may be shaped like a a wheel, but pilots yaw with foot pedals, something which I never fully got used to. Even in fly-by-wire aircraft, the designers often have to program fake control feedback to help tap these pilot reflexes. If you go into a stall or a spin, you can't type commands to the control surfaces, no matter how much you practiced it. Granted, zero-g vacuum maneuvers are fundamentally different, but the mind and body will adjust to that.

This new type of control system may be justified from an purely engineering point of view, it may even be superior, but it no longer takes advantage of the long lifetime of physical experience and training pilots already have in them the day they enter astronaut school. When a jammed thruster sent a Gemini capsule into uncontrollable 3-axis spins, it was Neil Armstrong's hands and ear canals that brought it under control, not frantic button and mouse pushing. Operating any machine relies on physical and manual skills picked up by long real-life experience, then refined on endless hours in a dedicated flight simulator. This is what is really meant by seat-of-the-pants flying. When an analog system undergoes failure, the body and brain adjust, adapt, recover. When a screen goes dark, the result is just instant, total disorientation. It may only be temporary,
but for a time you are helpless.

A purely digital user interface, even when working perfectly, does not take advantage of all that prior experience. Sure, you can probably control a bicycle with a keypad, too, but you'd have to learn to keep it rolling upright all over again, and you'd never be any good at it. We are monkeys, and we use, and coordinate, our hands and eyes and our perception of the gravity field when we climb trees. Its not a logical process at all.
