单项选择题

On Feb. 15, 1965, a timid but sober-headed high school student named Raymond Kurzweil appeared as a guest on a game show called I’ve Got a Secret. He was introduced by the host, and then he played a short musical composition on a piano. His secret was that the music was composed by a computer.
Kurzweil then demonstrated the computer, which he built himself--a desk-size affair with loudly cracking relays(继动器), hooked up to a typewriter.
People were more impressed by Kurzweil’s age than by anything he’d actually done. But Kurzweil would spend much of the rest of his career working out what his demonstration meant. Creating a work of art is one of those activities we reserve for humans and humans only. It’s an act of self-expression; you’re not supposed to be able to do it if you don’t have a self. To see creativity, the exclusive domain of humans, seized by a computer built by a 17-year-old is to watch a line blur that cannot be unblurred, the line between organic intelligence and artificial intelligence.
That was Kurzweil’s real secret, and back in 1965 nobody guessed it. Maybe not even him, not yet. But now, 46 years later, Kurzweil believes that we’re approaching a moment when computers will become intelligent, and not just intelligent but more intelligent than humans.
Computers are getting faster and the rate at which they’re getting faster is increasing. So if computers are getting so much faster, so incredibly fast, there might conceivably come a moment when they are capable of something comparable to human intelligence. Artificial intelligence. All that horsepower could be put in the service of imitating whatever it is our brains are doing when they create consciousness--not just doing arithmetic very quickly or composing piano music but also driving cars. writing books, or making witty observations at cocktail parties.
It’s impossible to predict the behavior of these smarter-than-human intelligences with which we might one day share the planet, because if you could, you’d be as smart as they would be. But there are a lot of theories about it. Maybe we’ll merge with them to become super-intelligent cyborgs(半机器人), using computers to extend our intellectual abilities the same way that cars and planes extend our physical abilities. Maybe the artificial intelligences will help us treat the effects of old age and prolong our life spans indefinitely. Maybe we’ll scan our consciousness into computers and live inside them as software, forever, virtually.
The one thing all these theories have in common is the transformation of our species into something that is no longer recognizable. This transformation has a name: the Singularity. It’s not a marginal idea; it’s a serious hypothesis about the future of life on Earth.
