Some funny tweets about this, a few of the good ones: I'm a professor in a movie. I only reach the main point of my lecture right as class is ending, then I yell at students about reading/homework as they leave. I'm a computer geek in a movie, I can break into any system by typing random keys extremely fast and then shouting "I'm in!". All the while this is happening green text will be projected scrolling across my face. Usually hired by a team breaking in somewhere, once inside I can control lifts, doors, CCTV, etc all using elaborate 3D graphics showing where everything is. The fact manufacturers make such fancy graphics just for lifts and doors will not be discussed.
