The History and Potential of Nanotechnology
TLDR Nanotechnology, first proposed by physicist Richard Feynman in 1959, involves manipulating individual atoms on a small scale. It has the potential to revolutionize various fields such as material science, medicine, and energy, but is still in its early stages of development.
Timestamped Summary

K. Eric Drexler's book "Engines of Creation" introduced the concept of nano-assemblers, nanoscale robots that could create nano-devices and potentially replicate themselves, but also raised concerns about the possibility of a "gray goo" scenario where uncontrolled nanobots consume all life on Earth.
