Chinese tech czar Jack Ma on Wednesday said there are no experts for tomorrow and all they know about is yesterday.
Addressing the World Economic Forum Annual Meeting here, the Alibaba executive chairman also told business leaders never to worry about competition and pressure.
"If you worry about pressure, don't be a businessman. Today, the great thing is everybody worries about everything," he quipped.
Replying to whether he encountered fear or doubts over the course of building Alibaba over the last 20 years, he said "There's no expert of tomorrow. There's only expert of yesterday."
Asked what kind of people he hires, he said, "When I hire people, I hire the people who are smarter than I am. People who four, five years later could be my boss. I like people who I like, who are positive and who never give up."
On the environment, he said, "If you think of Earth as a human, you're digging the oil and burning it, you're digging the coal, the bones. The Earth will have revenge."
