Open all the windows during takeoff and landing

Having the window open allows a passenger to see what s going on outside in a split second and it s not only because the window is opened. Say imagine if the plane crashes and the windows then just automatically open on its own leading way to a ray of bright sunlight coming into the passenger cabin. For a few seconds, all the passengers inside won t be able to see anything outside until their eyes adjust to the bright sunlight outside. That few seconds in the case of an emergency is crucial.
