Yeah, I was the guy who asked questions non-stop to the teachers
No seriously, what I meant was, from my limited knowledge of ship warfare here, I just meant if you suddenly needed to turn the ship fast or something, I think it would be a lot faster to turn by pressing a control stick left or right or whichever way, and the ship turns automatically. Regardless of whether or not the wheel is mechanically connected to the rudder (s) (which yeah I know it isn't), the ship will only turn as fast as you can turn the wheel.
And by the term "modern warfare," I just meant with the new types of torpedoes and such out there, if you ever encountered a threat, you would want to be able to maneuver around as fast as possible, which having a big wheel to turn would prevent I would think. If you encounter an enemy submarine, you don't want to have a slow method of turning (if a Navy ship would turn from the submarine in a confrontation; I don't know how it would work).
And yes, a wheel on a ship is cool, but I asked this because I assumed the wheel as an inferior way to steer a modern navy ship the size of a carrier (I thought that, not saying it is true, but I assumed so since cruise ships don't use wheels these days). Also, the military is supposed to emphasize function over "coolness." Having a big gun on the front of a Navy ship I am sure is cool to, but if you seriousy don't need it, don't have it.
And yes, I also know the chances of a modern carrier encountering a submarine or anything is pretty slim, but military stuff is supposed to be made for when the going gets rough; like how all fighter craft, even if they should never see a direct dogfight with another aircraft because of their high-tech missiles, they still have a machine gun on them that can fire if such a thing occurs.
