Ray Kurzweil, a pioneer of the current IT paradigm, discusses the roles of human beings in IT of the future. Kurzweil says unemployment in the U.S. is comparatively low, but jobs are being reallocated around the globe. National borders are not as important as in the past, because IT can work over the Internet. He says international competition is for the first time significant in types of work requiring education and skills, which is a trend that will continue. China has committed to building 50 Massachusetts Institute of Technology (MIT)-level educational institutions, and the result will be much intellectual property that will benefit all. In about a decade, says Kurzweil, routers and servers will be eliminated, as will desktop computers because new technologies will be tiny, almost invisible, and highly mobile. IT will concern itself with security, privacy, and protection, especially against malicious software. By the 2020s, millions or billions of nanobots will be inside the bloodstreams of humans and will extend cognitive abilities directly through a merger of biology with machines. Biotechnology is in its earliest stages, but over the next decade, most diseases that kill the large majority of people currently will be eliminated. Kurzweil says he slows the aging process by taking a specific diet and 250 supplements each day, which is part of an effort to reprogram his biochemistry. He says being natural is not desirable because biological evolution is not on the side of the human being.
