As we move over to more of a mobile device-centric world... I think the interaction model with devices is going to be much more voice-based.

I think I wanted to be a doctor. In Iran, the engineering and medical professions are worshipped. My father very much wanted me to be a doctor. I was certainly eager to please as a young man - as a kid, I should say.

When you go to a voice-based interaction, you can't tell people, 'Ask me this question and structure it in this way.' And if they ask a question, and you have a bad answer, first time, maybe they'll be okay with it. Third time, they're going to say, 'This is a complete waste of time. I'm going away.'

Where people work and their environment is becoming more and more important, especially for millennials.
