Is nanotechnology the last technology?
The subtitle to K. Eric Drexler’s book “Engines of Creation” is “Challenges and Choices of the Last Technological Revolution”. The implicit assumption being no other technologies will follow with equivalent impact. Is that a reasonable assumption? Perhaps, perhaps not. At a smaller scale and larger energy range are nuclear technologies. Or additional dimensions. The exact physical laws for this scale have yet to be worked out in full detail. At very large scales (planetary and solar system size and up) there has only been speculation on possible technologies. The same is true for attainment of high relativistic speeds. Breakthroughs in these realms might lead to technologies as revolutionary as nanotechnology.
