It is worth noting that Dragon does have physical controls, they're just backups hidden under the panel below the screens for emergencies. This is on top of the redundancy offered by the screens, where if one screen fails, the same controls are accessible on the other ones.

Plus, since it's supposed to fly autonomously, there isn't a lot of physical control to be done. This isn't like with cars where there's an argument that tactile controls are easier to adjust without looking away from the road.

I am not an astronaut. I prefer knobs. As my comment said, I think of them as a feature. I think the average astronaut would put up with their lack of preferred control schemes to go into space.
