B. F. Drexler

K. Eric Drexler is a scientist and engineer known for pioneering the concept of nanotechnology, which involves manipulating matter at an extremely small scale—billionths of a meter. He envisions future technologies where tiny machines, called nanobots, can build materials and devices atom by atom, potentially revolutionizing medicine, manufacturing, and energy. His ideas aim to enable precise control over materials and biological processes, opening possibilities for advanced healthcare and sustainable development. While his concepts are ambitious and sometimes debated, his work has significantly influenced scientific discussions on the potential and risks of molecular-level engineering.
