A plane is not a tank
I won't deny that certain air conditions can create a rough ride, but that's the exception rather than the rule for flying commercial. So:
1) The ride in an airliner is quite a lot smoother than a ride in a tank.
2) Under normal circumstances, those displays don't change on an aircraft without a pilot's command. Yes, I do fully agree that unplanned changes to the displays would be confusing; but they're not likely to change without reason.
3) Depending on the system, delay is usually unnoticeable. It's not like they'll be flying the plane using those displays as physical controls--they're information displays.
4) Most pilots do not wear gloves while flying. Even if they did, there are capacitive-capable gloves available even for clean-room level use.
Keep in mind, digital display systems are already in commercial aircraft--which invalidates almost your entire argument.
