问题     Do you want to live forever? By the year 2050, you might actually get your wish--providing you are willing to leave your biological body and take up residence in silicon circuits. But long before then, perhaps as early as 2008, less radical measures will begin offering a semblance (外表，伪装) of immortality.
    Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, plus all that you say and write, can be recorded analyzed and automatically indexed, and added to your personal chronicles. By the 2030s, it may be possible to capture your nervous system’s electrical activities, which would also preserve your thoughts and emotions. Researchers at the Laboratories of British Telecommunications have defined this concept as Soul Catcher.
    Small electronic equipment will pave the way for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro sensors under your scalp and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
    At first, the Soul Catcher’s companion system--the Soul Reader--might have trouble copying your thought in complete details. Even in 2030, we may still be struggling to understand the brain’s internal workings, so reading your thoughts and interpreting your emotions might not be possible. But these signals could be conserved for the day when they can be transferred to silicon circuits to rejuvenate minds as everlasting entities. Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.
    For people who chose not to live in silicon, virtual immortality could still ease the sense of futility (无用) that now haunts many people. Individuals would know their lives would not be forgotten, but would be preserved as a thread in a multimedia quilt that keeps a permanent record of the human race. And future generations would have a much fuller understanding of the past. History would not be dominated by just the rich and powerful, Hollywood stars, and a few elite thinkers.
The main idea of this passage is that ______.
选项 A、human beings long for an immortal life
B、people can live immortally as technology develops
C、there are many difficulties in making the Soul Catcher
D、the invention of Soul Catcher has great significance
答案B
