Claire is a very emotional woman who needs a good       .She finds this friend is a robot called Tony, who comes to help her in her home. He is        to her because he is so       and sympathetic. He becomes her best friend. She is        by his abilities but       by her feelings for him. She is disturbed because she thinks of him        a man even though he is not but is amused that other women        her and think they are having an        .Claire succeeds in overcoming her sense of failure, but in doing so she falls in        with Tony. His visit leaves her upset, frightened and hurt, which has replaced her sense of failure. She has been hurt by Tony because he is too nice rather        because he is not nice enough.

    The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

    I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to compete and then do better than their human ancestors. Once they do better than us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to improve environments. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.
