"People over the age of thirty were born before the digital revolution really started. We've learned to use digital technology-laptops, cameras, personal digital assistants, the Internet-as adults, and it has been something like learning a foreign language. Most of us are okay, and some are even expert. We do e-mails and PowerPoint, surf the Internet, and feel we're at the cutting edge. But compared to most people under thirty and certainly under twenty, we are fumbling amateurs. People of that age were born after the digital revolution began. They learned to speak digital as a mother tongue."
