Bill Gates is part of the world's elite brain trust but there's still one thing that makes the Microsoft founder feel "stupid."

During a Reddit "Ask Me Anything" session today, the global philanthropist said his one big regret in life has been not learning a foreign language.

"I feel pretty stupid that I don't know any foreign languages," Gates said. "I took Latin and Greek in high school and got A's and I guess it helps my vocabulary but I wish I knew French or Arabic or Chinese."

Gates said he hopes to follow the example of fellow tech titan Mark Zuckerberg, CEO of Facebook, in learning a second language.

"I keep hoping to get time to study one of these -- probably French because it is the easiest," Gates said. "I did Duolingo for a while but didn't keep it up. Mark Zuckerberg amazingly learned Mandarin and did a Q&A with Chinese students -- incredible."
