Today nanotechnology is still in a formative phase--not unlike the condition of computer science in the 1960s or biotechnology in the 1980s. Yet it is maturing rapidly. Between 1997 and 2005, investment in nanotech research and development by governments around the world soared from $432 million to about $4.1 billion, and corresponding industry investment exceeded that of governments by 2005. By 2015, products incorporating nanotech will contribute approximately $1 trillion to the global economy. About two million workers will be employed in nanotech industries, and three times that many will have supporting jobs.
~Mihail C. Roco, Senior adviser for nanotechnology to the National Science Foundation and a key architect of the National Nanotechnology Initiative link
(RR note: the $1 trillion figure is widely disputed)
