People in the US can now carry an artificial intelligence (AI) around in their pocket, where it waits patiently to be told what to do.
Siri, an iPhone application that understands spoken commands and uses the web to carry them out,is a byproduct from a US military project to develop an artificially intelligent assistant.
Many people's experience of a "virtual assistant" may be limited to Microsoft's annoying classic Mr. Clippy. But in the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop. It wasn't even stumped when I asked "do I need my umbrella today？" coming straight back with the local weather forecast.
A typical command might be: "Reserve a table for two at a good French restaurant in San Francisco." Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger.
In some ways Siri is just a fancy front-end to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what's new is the way it can interpret the intentions of its master or mistress and use those sites to put them into action.
Doing that requires the ability to actually understand the meaning of words you use, not just passing on keywords blindly, says Siri co-founder Adam Cheyer.
"Book a four-star restaurant in Boston seems pretty straightforward," says Cheyer, "until you realise that Book is a city in the US, and Star is also a city in the US, and there are 13 Bostons, and Star is also the name of a restaurant."
To cut through what Cheyer calls the "combined explosion of interpretations", Siri uses your location, and the history of the commands you've given. It knows that "book" is most likely a command verb, unless you happen to be near the city of Book.
Siri attaches probabilities to the interpretation of each word and cross-reference(参照) with your location and other data, some of which you must provide yourself.
According to the passage, Siri is most probably ______.
A．still at its experimental stage
B．very popular with iPhone users
C．a US military assistant software
D．an artificial intelligence software

But, while gizmos make a global network possible, it takes human cooperation to make it happen. Standage's insight in this regard adds depth to his technological history, he under scores the relevance to our own time of the struggles of Samuel Morse in America, William Cooke in England, and other telegraph pioneers. They made the technology work efficiently, sold it to a skeptical public, and overcame national and international bureaucratic obstacles. The solutions they found smooth the Internets way today.
Consider a couple of technical parallels. Telegrams were sent from one station to the next, where they were received and retransmitted until they reached their destination. Stations along the way were owned by different entities, including national governments. Internet data is sent from one server computer to another that receives and retransmits it until it reaches its destination. Again the computers have a variety of owners.
Then there is the social impact. The Internet is changing the way we do business and communicate. It makes possible virtual communities for individuals scattered around the planet who share mutual interests. Yet important as this may turn out to be, it is affecting a world that was already well connected by radio, television, and other telecommunications. The Associated Press, Reuters, and other news services would have spread the Stare report quickly without the Internet. In this respect, the global telegraph network was truly revolutionary. The unprecedented availability of global news in real time gave birth to the Associated Press and Reuters news services. It gave a global perspective to newspapers that had focused on local affairs. A provincialism that geographical isolation had forced on people for millennia was gone forever. Some seers naively hailed this as a force for world peace. They predicted that tensions over cultural and ethnic differences would relax as people interacted in real time. Visionaries say the same about the Internet. While communications can smooth this process, they don't automatically make it happen. As the experience of the past century and a half has shown, peace takes the will to make it work and sustained effort by all parties.
What does "the gem of late 20th century technology” refer to？
A．The telegraph.
B．Information theory.
C．Materials technology.
D．The Internet.
