Sense and sensibility

Scientists have advised against exaggerating AI's prowess after the Go victory. In the gaming field alone, AI researchers agree that computers, in their current stage, may not be able to beat humans in games that feature a high level of irrationality, including understanding of feelings and creativity.

"AlphaGo's learning and calculation prowess is based on formulas and data, but mahjong involves luck and emotions. To my knowledge, no AI is powerful enough to manage them," said Ren Yi, an expert on computer game AI and CEO of a Nanjing-based tech company.

Feng Jianfeng, chief scientist for a brain science and AI project launched by the city of Shanghai, also refused to bet on AI's definitive victory over human mahjong masters, as the game involves more human intelligence than calculation.

"AlphaGo's structure and arithmetic only emulates some primary functions of human brains, not including emotions, decision making, attention and creativity," Feng said. "It has just done something computers are very good at. It is a landmark and will greatly boost AI development, but AI still has a long way to go."

Feng's team is studying Alzheimer's disease with the help of AI, but defying public expectations of AI supplementing patients' declining brain abilities, Feng said what computers could do so far was helping make more accurate diagnoses by navigating through big data.

The disease affects tens of millions of elderly people worldwide and has no effective cure, though medical experts say playing games that activate brains could help with the prevention.

So for those worrying about the disease, the Chinese advice would be, instead of pinning hopes on AI, to sit with friends and enjoy a game of mahjong.
