As real pilots will attest, there is nothing more annoying about cockpit instruments, EFIS and mechanical alike, than bloody fingerprints all over them!
I spend so many hours of my life cleaning the greasy marks off, I need to consider treatment for OCD......oh, wait.
Anyway, I can see the day large long haul aircraft have a windowless design, with an area reserved with skylight displays for all round clear vision. The pilot will sit in a central area, touch screen control displays and side stick for emergencies. They will be like a zoo for the passengers to look at. In a low central position. Curved displays all round, very Star Trek.
It will happen. Providing the redundancy and back ups are good enough, imagine the selectable screens with synthetic overlay or IR imaging as well. As all controls will be configurable, there will be no separate type ratings either.
Fortunately, I'll be long retired by then.
