The car manufacturers are using electric window operators now, since they found that it’s less expensive than a hand crank mechanical system.
But, this is way less important than a flight control system.
Using motors to move the control surfaces, the electrical control system and multiple computers is a very complex design, vs push rods or cable and pulley.!
Existing autopilots use servos to operate the cables, so why go to full fly-by-wire.
The FAA will be looking very closely at their system before approving the design.
