4 Most Fascinating Moments From Prince Harry's Barack Obama Interview

The famous duo discussed the emotions Obama felt when he left the White House after President Donald Trump's inauguration, his views on social media, and his New Year's resolution in a BBC Radio 4 program broadcasted Wednesday.

Here are the four most fascinating bites:

Obama thinks social media is a tool that people use to focus on ideas that can reinforce their own views and warned against those who spend too much time on the internet.

"One of the dangers of the internet is that people can have entirely different realities," Obama said. "They can be cocooned in information that reinforces their current biases."

"The question has to do with how do we harness this technology in a way that allows a multiplicity of voices, allows a diversity of views, but doesn't lead to a Balkanisation of society and allows ways of finding common ground," he added.

Although Obama didn't mention Trump, who regularly tweets about policy as much as he does his personal feuds, he did suggest that face-to-face contact is a more effective way of finding common ground instead of lashing out at those with opposing views.

"Social media is a really powerful tool for people of common interests to convene and meet to know each other and connect, but then it's important for them to get offline, meet in a pub, meet at a place of worship, meet in a neighborhood and get to know each other," Obama said.

"Because the truth is that on the internet, everything is simplified and when you meet people face-to-face it turns out they're complicated," he added.

The moment Obama passed the torch to President Trump, the former president felt a sense of "serenity," even though there was a lot of work to be done to truly make America great again.

"I think it was a satisfying feeling that was mixed with all the work that was still undone, concerns about how the country moves forward, but you know, overall there was serenity there," Obama said. "More than I would have expected."

Although Obama didn't have time to finish everything he wanted to do, the former president believed his administration still ran a good race.

"One of the metaphors that I always used for the presidency is that you are a relay runner," he said. "There is the sense sometimes in any position of leadership that you, by yourself, do certain things and then it's over and I always viewed it as taking the baton from a whole range of people who had come before me. Some of whom had been heroic and some of whom had screwed up."

"But wherever you were in the race," he added, "if you ran hard, if you did your best, and that you then were able to pass that baton off successfully and the country was better off, the world was a little bit better off than when you got there, then you could take some pride in that. And I think we were able to do that."

But looking back, there are certain aspects of his presidency that Obama misses.

"Everything you do, every day you know can affect millions of billions of people, in some cases, and you have really smart, focused people who are there for the right reasons and who, over time, have built up trust and have learned to support each other and rely on each other - I miss that," Obama said.

Prince Harry lightened the mood with a speed round with simpler questions that may have revealed a lot more about Obama than the complicated ones.

Boxers or briefs? "We don't answer those questions."

LeBron or Jordan? "Jordan."

Aretha Franklin or Tina Turner? "Aretha is the best."

Kim or Khloe? "This one I have to defer on."

Prince Harry or William? "William right now."

"Suits" or "The Good Wife"? "'Suits' obviously."

The Rock or Chris Rock? "That's an interesting question. I like them both."

After Trump's election, horrifying mass shootings and destructive hurricanes, 2017 won't be remembered too fondly by many, but the man who ran on "Hope and Change" in 2008 is optimistic for 2018.

"If we take responsibility for being involved in our own fate, if we participate, if we engage, if we speak out, if we work in our communities, if we volunteer, if we see the joy that comes from our service to others than all of the problems that we face are solvable despite all of the terrible news that you see," Obama said.

Obama continued to reinforce that the world is more healthy, wealthy, educated and sophisticated than ever before by noting that just a few generations ago people like himself couldn't even imagine sitting in a hotel room like he was currently doing, much less serve the country in the way that he did for eight years.

"When you think about the strides that we made just in my life time, I have some grey hair but in the scale of American history, I'm a blink of the eye, you think about how much has changed and how much has gotten better, that has to make you more optimistic," he said.

As for Obama's New Year's resolution, the former president admitted that he doesn't believe in them, but strides to do a little better every day than the day before.
