Kim said a "good friend" had told him that about 25 years ago there was a heated debate inside the World Bank Group regarding investing in telephone poles in India.

Responding to a question he said robotics and automation was probably at its peak in China. "It's amazing what they're able to do with robots, and it's getting better and better and better. So things like weaving materials was something that it was thought that robots would not be able to do, but now they are doing it," Kim said.
"So, if you look around and say, well, are there other models -- that could be interesting? Well, again, if you go to China, not only do they have this heavily automated, heavily A.I.-dependent approach to heavy manufacturing, but they also have Alibaba and Tencent and WeChat, which is democratising access to capital, access to markets... access to marketing procurement -- even accounting," he said.
