When I signed with Scooter Braun and I decided to go overseas to promote my song, the only concern was how should I communicate with the public and the audience with my language. Scooter and I talked a lot about that: should we translate or not? Finally we didn't, and I think that was a really good decision.

My wife looks at the person Park Jae Sang and the singer who goes up on stage, Psy, as different people.

Technology challenges us to look at our human values. We can try to use technology to cure Parkinson's or Alzheimer's, which would be a blessing, but that blessing is not a reason to move from artificial brain enhancement to artificial intimacy.

I was standing on the shoulders of other science fiction writers like William Gibson, who had written 'Neuromancer' on a typewriter before home computers even really existed, and Neal Stephenson who wrote 'Snow Crash' in the early '90s and imagined an online virtual world before the birth of the modern Internet.

Without competition, the spectacular development of technology that we have seen in the last one hundred years in this country would not have happened.
