When asked if "YouTube is equipped with enough people to filter and delete these content," Pichai said: "We have made progress through a combination of machines and humans. Today, in 99% of cases There is no problem. Our goal is to continue to expand the results, so that the proportion of bad content is far below 1%."

But Pichay also pointed out that it is not realistic to ensure that 100% of the content is positive. He said: "This is difficult for any large-scale system. For example, the credit card system is still fraudulent."

Pichay also said that he believes YouTube will do better and make significant progress. In the future, Google will also strengthen its implementation to solve problems as quickly as possible.
