As a very laptop-friendly SM, I cannot imagine running a show without paper.
Conversely, I have run shows without flashlights. (Tiny studio space + blue gel + station lights = I guess I might have used it to charge glow-tape, but hardly anything else.)
Theatres do need flashlights (otherwise latecomers would be tripping all over the place), but stage managers? Useful, but not mandatory. Paper, on the other hand...
