My read from the interview is that he is just had no patience for how Kara was conducting the interview. My point is that the dismissive attitude he expresses is kind of funny and impressive considering all the pressure he (and his companies) are under.
At least from what you've quoted, I have a hard time seeing your point. Seems to be a fairly conservative conversation from a 47 year-old entrepreneurial billionaire physicist, and an interviewer. She asks questions and he gives her straightforward answers with no fluff.
While I would agree that he (clearly) doesn't play by the rules of mortals (how could you, and get to where he's gotten?), I'd hardly call this a matter of he just doesn't care about the interpersonal social status dynamics at play
