By the middle of the century, the inventor Ray Kurzweil suggests in his 2005 book The Singularity Is Near, human beings will live in perpetual clouds of nanobots, molecule-sized robots that spend each moment altering our micro-environments to our precise preferences. Over the longer term, he imagines that nanotechnology—the manipulation of matter at the molecular level—will let us change our shape and appearance, become immortal, and transfer our minds with ease between far-flung planets.
By contrast, the thriller writer Michael Crichton describes nanobots running amok in his 2002 novel Prey. With his signature mix of tech savvy and paranoia, Crichton imagines the tiny automatons forming "nanoswarms", clouds that visually mimic human beings in order to infiltrate and destroy us—sort of microscopic, sentient super-kudzu.
Both our hopes and fears regarding nanotechnology have been extreme from the beginning, if we take as the beginning K. Eric Drexler’s 1986 book Engines of Creation. Drexler, an engineer, described nanotech as the ultimate fulfillment of humanity’s dynamic, self-transforming tendencies: the ability to create whatever we want, whenever we want it, combined with an imperative to take this godlike new power to the stars and turn the universe into our playground. Drexler also described the dark twin of this vision: the "gray goo" scenario. Self-replicating nanobots, which proliferate by turning surrounding matter into copies of themselves, would go out of control, turning the entire Earth into themselves—the most homogeneous imaginable version of the apocalypse. In the words of a technophilic but precaution-prone acquaintance of mine, a computer programmer who has his wristwatch set to alert him if a tsunami approaches Manhattan: "The gray goo scenario should at least give one pause. "
Such disaster fears are already fueling calls for regulation, even with the technology barely out of the cradle. Nanotech-related products will soon account for $ 2. 6 trillion in sales each year, according to a London School of Business/Rice University study. The current applications are concentrated in products that benefit from highly efficient filtering or surface-application processes, such as microchips, car wax, and sunscreen. But down the road, the likely applications include molecule-perfect wound-healing, flawless cleaning processes, quantum computing, far easier bioengineering, much more efficient photon and electrical transfer, and much more. In a June 2007 press release, Consumers Union, publisher of Consumer Reports, noted that nanotechnology " promises to be the most important innovation since electricity and the internal combustion engine". At the same time, it called for more testing and oversight, warning that some nanotech applications "might pose substantial risks to human health and the environment".
It seems that nanotechnology______.
选项
A、facilitates manufacturing processes
B、provides us with a superb instrument
