What is the main topic of the passage?

Today, I ask you to focus on the challenges of the Information Age. The dimensions of the Information Revolution and its limitless possibilities are widely accepted and generally understood, even by lay people. But to make the most of it, we must acknowledge that there are challenges, and we must make important choices. We can extend opportunity to all Americans or leave many behind.We can accelerate the most powerful engine of growth and prosperity the world has ever known, or allow the engine to stall.

Of course, concerns about deflation and slow growth are closely interlinked.If the American economy were to slide into deflation, with prices actually falling, hopes for a sustained economic recovery would be dashed.Once prices start to fall, consumers and businesses postpone all but the most essential purchases. What is the point of buying something now if it will be cheaper in a few months’ time? It is easy to see how quickly the economy could slide back towards recession. Japan, in or close to recession for much of the past decade, is now experiencing its fourth consecutive year of falling prices.
