Speaking in an interview with CNN's Poppy Harlow recently, Google CEO Sundar Pichai said that YouTube is too big to completely repair the site's malicious content issues.
YouTube, owned by Google, has been burning for the past couple of years, as controversial content ranging from Sandy Hook's pioneers to supremacist content has existed despite the company's efforts to filter it out.
Harlow asked Pichai whether there would be enough people to filter through and remove such content.
"We have become much better at using a combination of machines and people," Pichai said. "So that's one of those things, let's say we get it right 99% of the time, you will still be able to find examples. Our goal is to take it to a very, very small percentage well below 1[ads1]%."  Pichai said Google probably can't get it to 100%.
"All major systems, it's tough," Pichai said. "Think of credit card systems, there's some scams in it … something when you run that scale, you need to think about percentages."
But Pichai added that he is "confident that we can make significant progress" and that "enforcement will be better." He also said that Google wants it to have addressed the issues before, since many of the videos have run in years
"It's a confirmation we didn't get it right," he said. "We are aware of some of the pitfalls here and have changed their priorities."
