Mark Zuckerberg announced in May that he wants to be Tony Stark and is attempting to create an AI assistant to better run his home. Zuckerberg's personal project may end up using the voice of Iron Man. After announcing on Facebook that his ?AI Jarvis? is in need of a voice, Robert Downey, Jr. responded a few hours later, stating ?I?ll do in a heartbeat...". And Zuckerberg responded, "This just got real."
