WHAT SCARES YOU ABOUT THIS? >> A COUPLE OF DIFFERENT THINGS. IN FACT, WHAT SCARES ME THE MOST IS WHAT -- I'LL CALL IT SOCIETAL CHOICES DO WE MAKE? WE DEFINITELY WANT THE BENEFITS OF THIS TECHNOLOGY AND WE WANT TO MITIGATE THE UNINTENDED CONSEQUENCES. >> Reporter: BUT NADELLA ALSO SEES THE POTENTIAL. >> STEVE JOBS HAS THIS BEAUTIFUL, BEAUTIFUL LINE WHICH IS "COMPUTERS ARE LIKE THE BICYCLES FOR THE MIND."
