Molecular nanotechnology (MNT) manufacturing means the ability to build devices, machines, and eventually whole products with every atom in its specified place. MNT is coming soon—almost certainly within 20 years, and perhaps in less than a decade. When it arrives, it will come quickly. Molecular manufacturing can be built into a self-contained, tabletop factory that makes cheap products efficiently at molecular scale. The time from the first assembler to a flood of powerful and complex products may be less than a year. The potential benefits of such a technology are immense. Unfortunately, the risks are also immense.
