Google CEO Sundar Pichai recently said in an interview with Poppy Harlow of CNN that YouTube was too big to fully address the site's harmful content issues.
YouTube, owned by Google, has been criticized over the past two years. Controversial content, ranging from Sandy Hook's filming negations to supremacist content, continued to exist despite the company's attempts to filter it.
Harlow asked Pichai if there would be enough humans to filter and delete this content.
"We have used a combination of machines and humans much better," Pichai said. "So that's one of those things. Suppose we get the right answer 99% of the time. You can always find examples. Our goal is to raise this percentage to a very small percentage well below 1%. "
Pichai said Google probably could not reach 100%.
"All large-scale systems are difficult," Pichai said. "Think about credit card systems, there are frauds in all of this … when you run on this scale, you have to think about percentages."
But Pichai added that he was "confident that we can make significant progress" and that "law enforcement will improve on it". He also said that Google wanted to solve problems faster because many videos have been released for years.
"We recognize that we have not done things right," he said. "We are aware of some pitfalls and have changed priorities."
