Eric Drexler

Eric Drexler is an American engineer and futurist best known for pioneering the concept of molecular nanotechnology and molecular manufacturing. He introduced the vision of nanotechnology as the precise, atomic-scale manipulation of matter to build complex structures and machines, outlined in his seminal 1986 work *Engines of Creation*. Drexler founded the Foresight Institute in 1986 to advance research and public understanding of nanotechnology's potential and risks.

Drexler's work synthesized ideas from chemistry, physics, and engineering to propose that future technologies could enable the construction of molecular assemblers—machines capable of building virtually any structure atom by atom. While some of his more speculative proposals have been debated within the scientific community, his foundational concepts have influenced nanotechnology research, synthetic biology, and long-term technological forecasting. He has remained a central figure in discussions about transformative technologies and existential risk, contributing to the intellectual foundations of the effective altruism and AI safety movements.

Eric Drexler is an American engineer and futurist who pioneered molecular nanotechnology in the 1980s. He introduced the concept of molecular manufacturing and atomic-scale engineering through *Engines of Creation* (1986), establishing the intellectual framework for nanotechnology as a transformative technology. As founder of the Foresight Institute, he has shaped discussions about long-term technological futures and existential risk.
