I notice some shortcuts in comics. Drawing each frame is a lot of work. You see it in animation too where a character leaves the room and you just hear what they are up to. Of course some will use the same sets of frames over and over for things like walking. With computers that got even easier. Now there's the 'AI' tools to take on some tasks. We are seeing another sort of revolution in art right now and it may not all be good.
