Jack Ma: World leaders must make 'hard choices' or the next 30 years will be painful

Ma said the emerging opportunities -- and risks -- from artificial intelligence and globalization are two of the topics that keep him on the road. "This is why I'm traveling, talking to all the government and state leaders and telling them move fast. If they do not move fast, there's going to be trouble," Ma said. "So when we see something is coming, we have to prepare now. My belief is that you have to repair the roof while it is still functioning."
