TSMC founder Morris Chang’s major worry: US-China decoupling

The one thing that comes closest to keeping Morris Chang, the tech king of Taiwan, up at night is decoupling of the world’s two largest economies, the United States and China.

“It looks like countries are mad at each other, and that worries me,” Chang, the 91-year-old retired founder of the Taiwan Semiconductor Manufacturing Company, said on Thursday at an Asia Society event in New York.
