Bill Gates, founder of Microsoft, recently said in an interview with CNN that the U.S. tariff policy has created a lot of uncertainty, which will have a huge impact on all walks of life, and this uncertainty will prevent companies from carrying out normal investment activities. Bill Gates also believes that the U.S. technology blockade against China has had the exact opposite effect. Not only has it failed to restrict China's technological development, but it has also allowed China to achieve full-speed development in areas such as chip manufacturing.
