In The Age of Spiritual Machines: When Computers Exceed Human
             Intelligence, Ray Kurzweil foretells a future where intelligent machines
             outnumber carbon-based life forms by the year 2099. While some of his
             claims may seem fantastic, Kruzwiel's credentials are impeccable, and many
             of his predictions for the late 1990s and early 2000s have come true.
             Thus, a close understanding and inspection of his ideas is warranted both
             by his credentials and track record. Perhaps one of the most important of
             the implications of Kurzweil's theories is upon human aging. Today, work
             on slowing the biochemical aging process is proceeding at a profound rate,
             and Kurzweil predicts that by 2020 nanotechnology will enable researchers
             to replicate DNA and proteins artificially, thus leading to the elimination
             of disease and even reverse aging. Other theorists argue that this could
             lead to a golden age for humankind, bringing about profound abilities for
             spiritual, emotional, and intellectual growth. At the same time, many
             other predictions based on Kurzweil's growth of computing technology are
             much more negative. Specifically, it is thought that new technologies will
             begin to make human labor obsolete, thus potentially leading to massive
             unemployment. Taken together, both Kurzweil's book and the implications
             that arise from it suggest a future that will be, at the very least,
             profoundly different from today, and present immense challenges for
             Kurzweil's qualifications for writing a book on artificial
             intelligence are impressive. Dr. Kurzweil has been active in the
             artificial intelligence community for decades. In 1975, he developed the
             first Charge Coupled Device (CCD) Flat Bed Scanner, and crated the first
             Omni-Font Optical Character Recognition Software a year later. In 1987,
             Kurzweil developed the Large Vocabulary Speech Recognition Software, and
             created a successful and precise mus...
