What if the electricity fails? What if the camera breaks? What if this, what if that? People had the same kind of very strong objections to fly-by-wire systems, and we've had planes for decades with no physical links between the controls in the cockpit and the control surfaces that move the plane. The number of accidents caused by failure of a fly-by-wire system? None. There are so many redundancies in these systems, it makes it very unlikely to fail.
Next... seeing outside isn't particularly important. Pilots don't really need to look out the window on these planes for flying. Especially when the plane is in fog or clouds, looking out the window can be actually confusing and disorienting and it's much safer to to look a the instruments. When coming in for a landing, the runway has a guidance system that guides the plane right onto the runway (ILS).
Plus, you can actually get a much better view of the outside using cameras and screens.
This being said, this is not an invention and it's not patent-worthy. As others mentioned, NCC-1701 had a viewscreen instead of a window... almost half a century ago.
