(2) Just as machines took over most of the heavy physical labor in the past, computers will take over more and more of our thinking tasks. The increasingly powerful problem-solving ability of the global computer system makes human fantasy shame. Today's supercomputers can calculate 1.4 trillion times per second, but scientists now expect an "ultra-high-speed" computing technology, which can reach a level thousands of times faster than today's fastest computers. Nowadays, new technologies that solve problems more effectively than using the original computing power emerge one after another.
