We all knew that Ashton was a bit of a techie - he's invested in companies like Spotify and Airbnb and played Steve Jobs on the silver screen. But he also has more altruistic ventures.
He's also mounting a tireless crusade against child abuse.
At the Senate Foreign Relations Committee, Ashton talked about the tech non-profit company he co-founded called Thorn: Digital Defenders of Children which creates computer software to fight human trafficking - with a special emphasis on stopping child abuse.

A terrible thing that happens far more often than it should - and is hard to control.
The sheer volume of illicit child abuse material online means that law enforcement isn't properly equipped to sift through the thousands of people searching for this content to focus on the potential hands-on offenders and content producers. People using the Internet to share child abuse material are doing so with a low risk of getting caught.

Around the world, law enforcement seize child sexual abuse material for cases and review the content independently - but don't share that information. They have no way to determine if the images they find on hard drives are of children who have already been identified or if they are new victims and require further action.
Ashton is the father of two young kids with Mila Kunis, one aged only three months old and the older one is two years old. For him, these problems are a huge challenge that he's willing to dedicate himself to.

He said: "I've met victims in Russia, victims in India, victims who have been trafficked in Mexico... and all across our country. I've been on FBI raids where I've seen things that no person should ever see," said Ashton Kutcher at the meeting, his voice breaking.
"I've seen video content of a child that's the same age as mine being raped by an American man that was a sex tourist in Cambodia.
"And this child was so conditioned by her environment that she thought she was engaging in play.
"We had received a call from the Department of Homeland Security, telling us that a seven-year-old girl was been abused and that content was being spread around the dark web. He'd been abused for three years and they'd watched her for three years and they could not find the perpetrator. Asking us for help," he said.

"We were the last line of defence. An actor and his foundation were the potential last line of defence.
"That's my day job and I'm sticking to it."
One in five victims of human trafficking is a child, according to the NSPCC. Over 700 children were identified as potentially being trafficked last year in the UK. The most common countries to be trafficked from are UK, Vietnam, Slovakia, Romania and Nigeria.
