Trend Towards Miniaturization

Our manufactured systems have shrunk over time: radios, pumps, typewriters, motors, so that today an electric motor sixty microns or sixty millionths of a meter across or less than a hair's breadth wide, can still spin when properly electrified. But static electricity poses difficulties when manufacturing anything this small. To shrink something in the lab is difficult but not impossible, but manufacturing our something in large enough batches is the rub. Our technology, great that it is, still limits our building small. We can either fit small parts together to make larger pieces, or we can make flat things all of one piece on chips.
