Facebook's Zuckerberg unveils plan to build artificially intelligent butler

Mark Zuckerberg wants to build an artificially intelligent assistant in 2016 to help run his home and assist him at work, the Facebook Inc founder and chief executive said on Sunday.

Zuckerberg, who commits to a new personal challenge every year, revealed his plan in a Facebook post.

"You can think of it kind of like Jarvis in Iron Man," Zuckerberg wrote, referring to an artificially intelligent butler who appears in the Marvel comic books and movies.
