Nanotechnology
The advanced automation section has mainly focused on automation technologies using robotics and 'macro'-scale systems, as it describes systems that could be achieved with today's technology. However, even more sophisticated and capable technology using nano-scale devices (at the atomic and molecular scale) are likely to be feasible in the coming decades, that could ultimately give us a similar level of control over matter that we currently have over information using computers. See also related Diamond Mechanosynthesis.
This is likely to end up being a mixture of top-down engineering techniques related to current semi-conductor fabrication and micro-electro-mechanical systems (MEMS), true bottom-up molecular engineering and self-assembly, and derivatives from biotechnology . This is likely to give us systems of unprecedented precision, capability and small size that will further revolutionise manufacturing, power generation, agriculture and medicine.
Nano-scale devices that could be sent inside the human body as a medical intervention are being developed. Mice have already been cured of type-I diabetes with this method[1].
(However as interesting and capable as advanced nanotechnology is likely to be, it is not actually a requirement for the development of an advanced post-scarcity society, which can be achieved with today's technology).
