Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include. "I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene. The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented reality, a technology already available on smartphones and tablets that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would _ showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you. "As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. "We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device that's hundreds and hundreds of dollars." Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones. "It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. "There's gonna be improvements to that, and this is a step there. " According to Sam Biddle, the smartphone-like glasses are _ . A) necessary for teenagers B) attractive to New Yorkers C) available to people worldwide D) expensive for average consumers

Well,maybe I don't have to worry about my laptop and kitchen appliances yet.After I use them I can always pull the plug.But in the future,machines might find a way to prevent us from switching them off.There's a scary thought! Professor Stephen Hawking warned a few months ago about the possibility that artificial intelligence could evolve and end up beyond human contro1.He suggested that machines could" _ the end of the human race". Maybe the problem with computers too clever for us is not that they are evil or rebellious.What could put us in danger is that they might be too efficient.That's what philosopher Nick Bostrom from the Future of Humanity Institute at Oxford University believes.He says that machines are indifferent to humans and in pursuit of their own goals,the destruction of people might be just collateral damage.A machine would not take pity on you. I'm glad my machines at home are"dumb".All my vacuum cleaner wants to take over is the carpet in my living room.Let's hope they don't create an appliance which wants to take over the world!
