Intelligent Machines
1. Medical scientists are alreadyputting computer chips (芯片) directly into the brain to help people who have Parkinson'sdisease, but in what other ways might computer technology be able to help us?Ray Kurzweil is author of the successful book The Age of Intelligent Machinesand is one of the world's best computer research scientists. He is researchingthe possibilities.
2. Kurzweil gets computers torecognize voices. An example of this is Ramona, the virtual (虚拟的) hostess of Kurzweil'shomepage, who is programmed to understand what you say. Visitors to the sitecan have their conversations with her, and Ramona also dances and sings.
3. Kurzweil uses this technologyto help people with physical disabilities. One of his ideas is a "seeingmachine". This will be "like a friend that could describe what isgoing on in the visible world," he explains. Blind people will use avisual sensor (探测器 ) which will probably be built into a pair of sunglasses. Thissensor will describe to the person everything it sees.
4. Another idea, which is likelyto help deaf people, is the "listening machine" This invention willrecognize millions of words and understand any speaker. The listening machinewill be able to translate into other languages, so even people without hearingproblems are likely to be interested in using it.
5. But it is not just abouthelping people with disabilities. Looking further into the future, Kurzweilsees a time when we will be able to download our entire consciousness onto acomputer. This technology probably won't be ready for at least 50 years, butwhen it arrives, it means our mind will be able to live forever.
