Eventually, many mechanical tools will fail. And sometimes, they fail in an unpredictable way. Polaroids cameras are no exception: old plastic cameras made in the 1970s that survived long summers in cars with no air-conditioning. Simpler objects, for simpler times. But even in an era with no Internet and no cellphones glitches could still occur, with the difference that all mechanical faults would be permanently recorded on shiny photographic paper.
