"I like playing with ideas that invite people to think. I also like old-fashioned, upbeat themes and happy endings. Although life doesn't always seem that way, I believe that in the long term things get better. I don't think we're about to overpopulate the planet, blow ourselves into oblivion, poison ourselves into extinction, degenerate into Nazis, or disappear under our own garbage. For ten thousand years the power of human reason and creativity has continued to build better tomorrows, and nothing says it has to change now."
