Design a machine, possibly including humans as "parts," to automatically turn those million pages. Maybe the machine is just a single human, serially, turning pages, but that's slow. There must be something better! How easy is it to design a reliable system, considering human/machine interaction and everything we know about human behavior and constraints like human attention, potential injury, dry fingers, etc.? How simple is the design?
