These three visionaries changed the way we live our daily lives.

Bill Gates, co-founder of Microsoft, describes how, as a teenager, he first envisioned the potential for computers to become fixtures in our homes. Larry Page and Sergey Brin, founders of Google, talk about their accidental discovery of the algorithm that would allow us to search and make sense of the new world-wide web's information explosion. And they all talk about taking risks to embrace the future.
