William Kunz is a computer genius (天才). When he was just 11, Kunz started writing software programs, and by 14 he had worked out his own computer game. As a high school first-year student in Houston, Texas, he won first prize in a science fair for a program he wrote. In his third year, he took top prize in an international science and engineering fair for designing a program to analyze and sort DNA patterns. Kunz went to attend Carnegie Mellon, one of the nation's highest-ranked universities in computer science. After college he got a job with Oracle in Silicon Valley, writing software used by companies around the world. Three years later, Kunz is in his first year at Harvard Business School. He left software engineering partly because he earned much less than his friends who were going into law or business. He also worried about job security (保障), especially as more companies move their programming outside the country to lower costs.
