Taiwan’s “digital minister,” Audrey Tang, a computer prodigy and entrepreneur who taught herself programming at age 8, says she’s a “civic hacker” who like a locksmith uses specialized skills to help rather than harm. Appointed by leaders hoping to better connect with young voters who helped sweep independence-leaning President Tsai Ing-wen into office last year, the 35-year-old Tang is using her expertise to more directly involve the public in policymaking, and to counter “fake news.”
