The promise of Nanotechnology takes decades longer to materialise than was originally anticipated. However, the rise of 'Micro Machines', complex, cheap, precision engineered devices, has profound effects. The economic impact of micro machine technology is that practically all device that can become smaller do so, using less material and less power. Whilst in this future fewer skilled craftsmen are required, the new profession of micro-machine designer comes to the fore. Computers are used extensively in refining the designs, but do not have the creativity required for the full task.
