Quick Summary

K. Eric Drexler is an American scientist known for his advocacy of nanotechnology. He earned the first Ph.D. in molecular nanotechnology from MIT. Drexler envisioned molecular machines, called "assemblers," that could manipulate individual atoms to build structures. He also proposed "replicators," capable of self-copying to construct larger objects. Drexler suggested these molecular machines could revolutionize medicine by acting as augmented immune systems or repair machines within cells, offering surgical control at the molecular level. His ideas have sparked significant discussion about the potential and ethical implications of nanotechnology.1
