GUANGZHOU Last year, AlphaGo, a computer program developed by Google to play the ancient Chinese board game Go, stunned the world by beating the South Korean professional player Lee Se-dol. Now, 19-year-old Ke Jie may be humanity's best hope of regaining dominance over the machines.
"Without doubt, he is the world's best Go player," Yuta Iyama, a professional player who was the first person to hold all seven major Japanese Go titles simultaneously, said of Ke, who in December won the 2016 Samsung Cup, his fourth international title.
