Robert Downey Jr. makes Mark Zuckerberg offer on voicing 'Iron Man'-inspired artificial intelligence

Facebook founder Mark Zuckerberg has received an offer from a famous face for his personal artificial-intelligence assistant: Robert Downey Jr. Mr. Zuckerberg turned to fans on Thursday for suggestions on who might provide the voice work for his AI and soon heard from Marvel's "Iron Man." The famous actor, whose character Tony Stark interacts with a computer named Jarvis, said he would be happy to oblige -- for charity. "I'll do in a heartbeat if Bettany gets paid and donates it to a cause of Cumberbatch's choosing…that's the right kind of STRANGE!" Mr. Downey Jr. said on the CEO's Facebook page.
