Drexler described how molecular assemblers that could build objects atom-by-atom would eventually be used for everything from medicinal robots to environmental scrubbers that clean the air, water, and soil of pollutants.
Nanomachines will also lead to a new process known as nanoassembly, where everyday materials will be assembled at the molecular level to create “smart materials.” This could include products likethat apply themselves to your body.
The technology will become more commonplace and affordable since nanoassemblers will be used to create more nanoassemblers without the usual machining, pollution, or waste. In time, they will become household items, churning out products on demand and recycling ones that are no longer in use., conditions like heart disease, stroke, infectious diseases, and cancer will have become a thing of the past.
